What Type of Coolant Does Volkswagen Use?

Volkswagen Polo

When maintaining your Volkswagen, it’s essential to use the correct type of coolant.

Knowing the correct type of coolant your car requires can help avoid expensive repairs and keep your car performing well.

In this post we will cover the correct type of coolant for the different Volkswagen models and what you need to know when selecting coolant.

Coolant for Newer Volkswagen Models (Post-1996)

Starting in the mid-1990s, Volkswagen introduced new coolant formulas that are more environmentally friendly and offer longer service intervals. Here’s a look at the coolants recommended for newer VW models:

G12 Coolant (Pink or Purple)

In the mid-1990s, VW began using G12 coolant, which is pink or purple. G12 is an ethylene glycol-based, organic acid technology (OAT) coolant that’s free of silicates, phosphates, and other inorganic additives, making it ideal for modern engines with aluminum radiators. G12 coolant is designed for longer life, typically up to five years or 150,000 km, whichever comes first.

G12+ and G12++ Coolants

These versions are updated formulations of G12, offering even better performance and compatibility. G12+ (also pink or purple) and G12++ are backward-compatible with G12 and can often be used if G12 is not available. However, it’s still crucial not to mix G12/G12+/G12++ with G11.

G13 Coolant (Purple)

In recent years, Volkswagen introduced G13 coolant, a more environmentally friendly option that incorporates glycerin as a primary ingredient. This purple coolant offers similar properties to G12 but with lower environmental impact. G13 is compatible with all newer Volkswagen models, especially those produced post-2008. G13 is fully compatible with G12+ and G12++, and they can be mixed if needed.

Coolant for Older Watercooled Volkswagen Models

Older watercooled Volkswagen models—generally those produced before 1996—often have different cooling requirements compared to newer models. Here’s what you need to know:

G11 Coolant (Blue/Green)

Volkswagen’s G11 coolant, a blue or green liquid, was primarily used in vehicles from the 1980s to the early 1990s. It’s a silicate-based coolant designed to prevent corrosion in older engines. G11 is compatible with aluminum components and is best suited for engines without modern electronic cooling systems. G11 coolant typically needs to be replaced every two years or so.

Mineral-Based Coolants

For classic VW watercooled models, some enthusiasts prefer mineral-based coolants due to their compatibility with older engine components. However, it’s essential to ensure these coolants meet VW’s specifications. Using generic or incompatible coolants can lead to scaling and corrosion.

Consequences of Using the Incorrect Coolant

Understanding the correct types of coolant for your Volkswagen is essential to avoid serious risks to your vehicle’s engine.

Choosing a standard coolant instead of the recommended type can lead to several problems that may cause significant damage to your engine.

Here’s why using the right coolant is crucial:

  • Corrosion Problems: Metal, rubber, and plastic components may corrode, compromising the integrity of your engine.
  • Blockage Issues: Deposits might build up in the radiator core, leading to blockages that impair coolant flow and threaten severe engine damage.
  • Chemical Incompatibilities: Mixing different types of coolants can trigger harmful chemical reactions, jeopardising the entire cooling system.

Using the incorrect coolant isn’t a minor mistake; it can cause serious problems in your engine.

Factors Affecting the Cost of a BMW Engine Replacement

Several factors contribute to the overall cost of replacing a BMW engine, including:

  1. Engine Type: BMW offers various engine types, from four-cylinder turbos to inline-six, V8, V10 and even V12 engines. Generally, the more cylinders or turbochargers an engine has, the more expensive it is to replace.
  2. Parts and Labor: Labour costs can add significantly to the overall expense. Replacing a BMW engine requires specialised skills, and the complexity of the job often demands several hours of work.
  3. Condition of Replacement Engine: BMW engines can be purchased as brand new, rebuilt, or used. A new engine is the most expensive option but often comes with a full warranty. However, a brand new engine may not be available for all models, especially older ones. Rebuilt engines are more affordable and have some warranty coverage, while used engines are the cheapest but carry the highest risk and may lack warranty.
  4. Model Year: Older models generally have less complicated engines, making them more affordable to replace. Newer models often have advanced technology and more sensors, which can increase replacement costs.
  5. Where You Get the Replacement Done: Opting to replace the engine at a BMW dealership will likely cost more than using an independent BMW specialist.

Additional Costs to Consider

Aside from the engine replacement itself, there may be additional costs involved, including:

  • Diagnostics and Testing: Before replacement, diagnostics are essential to confirm that the engine is the only component needing attention.
  • Additional Repairs: If there is damage to other components, such as the transmission or cooling system, those may also need repairs. It’s common for other parts, like hoses, belts, and seals, to be replaced alongside the engine, adding a few hundred dollars to the final bill.
  • Towing: If your BMW is not drivable, you’ll need to factor in towing costs, which vary depending on distance but generally range from $50 to $200.
  • Certification: If you choose a larger or more powerful engine, you’ll need LVVTA certification, which adds approximately $700 to your expenses and additional time to go through the process.

What Kind of Engine Oil Should You Use In Your Volkswagen?

White Volkswagen Golf Mk8

Looking to change the oil in your Volkswagen?

In this blog, we are going to cover the recommended oils for different Volkswagen models so that you can pick the right one for your car.

Recommended Engine Oils for Modern Volkswagen Models

Depending on your Volkswagen’s make, model, and year, you may need a different type of oil. Here are some recommended options based on common modern Volkswagen models:

1. Volkswagen Golf, Golf GTI & Jetta

Recommended Oil: 5W-30 for turbocharged engines; 0W-20 for non-turbocharged models, meeting VW 502.00 or VW 508.00 specifications.

Volkswagen Passat

Recommended Oil: 5W-40 or 5W-30, meeting VW 502.00/505.00 specifications.

Volkswagen Tiguan

Recommended Oil: 5W-30, meeting VW 504.00/507.00 specifications.

Volkswagen Touareg

Recommended Oil: 5W-30 or 5W-40, meeting VW 502.00/505.00 specifications.

Oil Recommendations For Older Watercooled Volkswagens

For older water-cooled Volkswagen models, such as those from the 1970s to early 1990s (like the Volkswagen Golf & Jetta Mk1-MK4), the recommended oils often differ from modern models because of their specific engine requirements. Here are some general recommendations to ensure optimal performance and protection for these classic water-cooled engines:

1. Viscosity Recommendations

  • 10W-40 or 15W-40: These viscosity grades are generally recommended for older Volkswagen models, especially in moderate climates. They offer balanced protection, providing sufficient thickness to lubricate older engines, which may have slightly looser tolerances than newer models.
  • 20W-50: This is suitable for warmer climates or high-mileage engines that may experience higher oil consumption or have slightly worn engine components. The higher viscosity can help reduce oil leaks and maintain stable oil pressure.

2. Mineral Oil vs. Synthetic Oil

  • Mineral Oil: Older Volkswagen engines were originally designed for mineral oil, so if your vehicle is in mostly original condition, sticking to a high-quality mineral oil (such as 10W-40 or 15W-40) can be a good choice.
  • Synthetic Blend: If you’re looking for improved performance and protection, a synthetic blend is often suitable for older engines, providing better heat resistance and protection against deposits.

Understanding VW Engine Oil Specifications

Volkswagen has developed specific oil standards to ensure optimal engine performance. Here are some common VW specifications and what they mean:

  1. VW 502.00 / 505.00: Designed for gasoline engines, this specification is recommended for older models and provides protection under a variety of driving conditions.
  2. VW 504.00 / 507.00: Common in newer Volkswagen models, these specifications are optimised for extended oil change intervals and offer low sulfur and phosphorus levels, making them suitable for turbocharged engines and helping to protect the vehicle’s emissions system.
  3. VW 508.00 / 509.00: These specifications are designed for the latest Volkswagen engines, focusing on fuel efficiency and emissions control. Oils meeting this standard are usually low-viscosity oils like 0W-20.

Why Synthetic Oil Is Preferred for Volkswagen

Volkswagen engines typically require synthetic oil due to its superior performance benefits. Synthetic oil offers:

  • Extended Oil Change Intervals: Synthetic oils don’t break down as quickly as conventional oils, allowing for longer intervals between oil changes, which aligns with Volkswagen’s recommended maintenance schedule.
  • Improved Fuel Efficiency: Synthetic oil reduces engine friction, which can improve fuel economy slightly compared to conventional oil.
  • Better Performance in Extreme Temperatures: Synthetic oils remain stable in both high and low temperatures, making them ideal for Volkswagen engines that may face a variety of driving conditions.

Importance of Viscosity Grades

The numbers on the oil label, such as 0W-30 or 5W-40, indicate how the oil behaves at different temperatures.

For example, a lower viscosity oil like 0W-20 flows more easily in colder conditions, improving performance during chilly starts. Conversely, a higher viscosity oil such as 5W-40 offers better protection at higher temperatures.

Volkswagen recommends specific viscosity grades for each model to ensure optimal engine performance and longevity. Using an incorrect viscosity can lead to increased wear or even engine damage.

Additionally, consider your local climate when selecting oil—5W-40 works well up to 50°C, whereas 0W-20 is better suited for cooler conditions.

Effects of Incorrect Oil Use

Using the wrong type of engine oil in your Volkswagen can lead to serious problems.

For starters, if you don’t use the recommended oil grades, you might invalidate your vehicle’s warranty.

The incorrect oil viscosity results in inadequate lubrication, which increases friction and wear, potentially damaging your engine. This could cause parts such as camshafts and bearings to wear out early, leading to costly repairs.

Additionally, using unsuitable oil can reduce your fuel efficiency, affecting your spending each time you refuel. Low-quality oil often causes sludge to build up, which can choke your engine’s performance.

This not only reduces efficiency but could also cause your engine to overheat, posing a risk of severe damage.

It’s essential to choose the correct oil to maintain the health of your VW.

Recommended Oil Change Intervals

For most models, it’s recommended to change the oil every 16,000 kilometres or once a year, whichever comes first. If you’re using synthetic oil, this 16,000-kilometre interval is typically adequate.

However, if conventional oil is used in your engine, consider changing it every 8,000 kilometres.

Always monitor your oil level and quality, and adjust your oil change frequency based on your driving habits and the environment. Regular changes prevent sludge accumulation, protecting your engine from wear and maintaining its performance.

How to Check Transmission Oil on a BMW

Checking BMW Transmission Oil

Need to check the transmission oil in your BMW?

Depending on which BMW you have, there are different procedures you need to follow.

In this blog, we will cover how to check the transmission oil of models both with and without a dipstick for the transmission.

How to Check BMW Transmission Fluid Levels

Here are the procedures you need to follow for checking the transmission fluid level on your BMW.

Regardless of which transmission you have, you will want to warm up the fluid, ideally by driving the car for a short trip.

For Transmissions With a Dipstick (Older Models)

  1. Find the transmission fluid dipstick, which is usually located near the oil dipstick under the bonnet.
  2. Remove it and check the fluid—it should be clear with a light pink hue. If it appears dark or has a burnt smell, it may be time to change it.
  3. Clean the dipstick, reinsert it completely, then remove it again to check the level. If it’s below the Full mark, use a funnel to add the correct type of transmission fluid.
  4. Regularly checking this each month can prevent future problems.

Sealed Transmission Procedure

Sealed transmissions in BMWs need a particular method for checking as they don’t have a dipstick.

You must go to a professional who can access the fluid through service ports. Only qualified technicians should manage this task to prevent damage to your system.

Although these transmissions are sealed, they still need regular maintenance. If you hear unusual sounds, experience hesitation in changing gears, or face delays when accelerating, these might indicate that the fluid levels or quality are affected.

It’s advisable to have these checks carried out during regular service visits. This ensures your transmission works well and prolongs its life, keeping your BMW in excellent condition without unnecessary complications.

Manual Transmission

Manual transmissions typically do not have any way to check the fluid. The only way to check the fluid is to drain and refill the gearbox.

How Often Should You Check Your Transmission Fluid

Under normal conditions you shouldn’t need to regularly check your transmission fluid.

The only reason to do so would be if you notice leaking and need to make sure you have enough fluid in the transmission.

BMW transmissions have “lifetime” fluid, though this should be changed around the 100,000kms mark.

Need Your BMW’s Transmission Fluid Changed?

As BMW service specialists in Auckland, we can carry out all transmission servicing on your BMW.

To get your fluid changed, speak to us today by calling 09 441 3635 or emailing service@dodsonmotorsport.com.

How to the Check Oil Level On a BMW

BMW Engine

When maintaining your BMW, it’s essential to check the oil level regularly to ensure your engine operates efficiently.

However, it might not be as simple as it may seem, since newer BMWs do not have a dipstick.

In this blog, we will explain the process of checking the oil on your BMW for both models with and without a dipstick.

How to Check and Top Up Oil On BMWs

On BMWs With a Dipstick

Here is the process for checking the oil on your BMW which has a dipstick:

  • Park on Level Ground: Make sure your vehicle is on a flat surface for a correct reading.
  • Use the Dipstick: After letting the engine cool, remove the dipstick (usually a red or yellow handle). Clean it off, put it back in, then take it out again to see the oil level.
  • Add Oil if Needed: If the level is low, check your owner’s manual for the recommended oil type. Use a funnel to slowly add oil, checking regularly so you don’t put in too much.
  • Recheck and Replace Cap: After adding oil, check the level again and ensure the filler cap is tightly secured.

On BMWs Without a Dipstick

For BMWs without a dipstick, you will need to check the oil level through the iDrive system. Here’s how you do this:

  • Turn on the ignition (without starting the engine).
  • Go to the iDrive system (BMW’s infotainment system).
  • Navigate to “Vehicle Info” or “My Vehicle,” then select “Vehicle Status.”
  • Look for “Engine Oil Level” and select it.
  • The system will measure the oil level electronically and display the result.
  • If you need to top it up, do so and then repeat this process.

How Often Should You Check the Oil?

Your BMW’s performance and longevity depend on regular oil checks, ideally done at least once a month.

Before any long journeys, it’s essential to check your oil to avoid unexpected engine problems. If you’re driving an older model, you might need to check your oil more frequently, as these cars can lose or burn oil quicker.

Regular monitoring of your oil level not only keeps your engine running smoothly but also ensures you’re on track for necessary oil changes, typically every 10,000-15,000 kilometres.

It’s important to know the differences between engines; for example, the M54 is known for its reliability, while the N52 may require more frequent checks of its electrical components and oil levels.

Additionally, high-spec Coupé models, though rarer, have increased in market value, making them a potentially good investment.

Check the Maintenance History

When reviewing the maintenance history of a BMW Z4, focus on service records that show routine checks and repairs, particularly for engines such as the M54 and N52, which are known for certain problems.

It’s vital to check for regular oil changes—look for them every 16,000 km as suggested. This regular maintenance ensures that the engine has been looked after and prolongs its life.

  • Regular Oil Changes: Look for clean, amber-coloured oil at the correct levels, which helps maintain engine efficiency.
  • Documented Repairs: Ensure there’s a detailed log of repairs, such as the replacement of a faulty DISA valve or an electric pump, demonstrating proactive maintenance.
  • Soft Top Care: Check that the convertible roof is well-kept, free from water damage and operates smoothly.

A high mileage isn’t necessarily a problem if the car has been consistently well maintained.

Notable Z4 Issues to Look For

Roof Mechanism Failure (Convertible models)

The electric roof on the Z4 can sometimes fail due to water damage to the motor. This is often caused by blocked drainage channels, leading to water ingress into the motor compartment.

Steering Issues

Some Z4 owners report problems with the electric power steering, particularly stiffness or “sticky” steering, especially noticeable at higher speeds or during warm weather. This can be due to faulty steering column components.

Engine Oil Leaks

Oil leaks from the valve cover gasket or oil filter housing gasket are common, especially as the car ages. If not addressed, this can lead to oil loss and engine damage over time.

Cooling System Problems

Like many BMWs, the Z4 is prone to issues with the cooling system, particularly the water pump and thermostat. Plastic components in the cooling system can become brittle over time and may crack or fail, leading to overheating.

Why You Must Use the Right Diff Oil In Your BMW F80/F82 M3 & M4

BMW F80 M3

The BMW F80 M3 (sedan) and F82 M4 (coupe) use a limited-slip differential (LSD). These differentials require special oil to the specific design of the LSD.

If the wrong oil is used, the LSD units will wear out prematurely, and it’s not a cheap or simple fix.

In this blog post, we will cover this in more detail and tell you which oil you need.

What Oil Should You Use For the F80/F82 LSD?

The correct oil to use on the F80/F82s is BMW’s proprietary differential fluid specifically formulated for these vehicles, known as BMW SAF-XJ + FM Booster (with the “FM” standing for Friction Modifier).

The rear differentials in these vehicles need this specific type of oil, which includes the friction modifiers to ensure smooth operation of the clutch plates in the LSD.

What Happens If You Use the Wrong Oil?

If the wrong oil is used—such as regular gear oil without the proper additives—the friction characteristics inside the LSD can be altered, leading to increased wear of the clutch packs and the mechanical components. This can cause premature wear, noise, or even failure of the differential.

Here’s why using the correct oil is critical:

  1. Friction Modifier Additives: The special oil for BMW LSDs includes additives that reduce friction between the clutch plates, ensuring proper lock-up during cornering and smooth disengagement when it’s not needed. Without this, the LSD can bind or slip incorrectly, leading to uneven wear.
  2. Heat Dissipation: The right oil also helps dissipate heat effectively, which is crucial for the longevity of the differential. Overheating can lead to early failure of internal components.
  3. Expensive Repairs: Replacing or rebuilding an LSD is not a cheap repair, often costing thousands of dollars, especially when you factor in labor costs. Avoiding premature failure through proper oil maintenance can save significant costs.

Are BMWs Reliable After 100,000 Kilometers?

BMW E39 With Over 100,000 KMs

Are you considering buying a higher mileage BMW and want to know how reliable they are after 100,000kms?

Some owners report that their well-kept BMWs are very durable, while others warn of expensive repairs that might be needed after this distance.

In general, BMWs tend to be reliable cars, and if they are looked after they can go well past the 100,000 KM mark, often even past the 200,000 KM mark or more without major issues.

There are a number of factors that will impact how reliable a BMW is likely to be, especially in the higher mileage range. In this post, we will cover what you need to know regarding BMW reliability past the 100,000 KM mark.

How Long Do BMWs Last?

Many BMWs often exceed 100,000 kilometres without losing reliability, as long as they’re regularly maintained.

Many people consider cars over 100,000 km on the odometer to be close to the end of their life, but with BMWs, this is not the case.

Typically, a vehicle covers about 20,000 km each year, so reaching 100,000 km is quite normal and doesn’t usually mean a drop in performance.

On top of that, it is not uncommon to find BMWs past the 100,000 KM range and well into the 200,000 KM range, especially in the older generations like E30s, E36s and E46s.

Maintenance Importance and Service History

When evaluating the reliability of a BMW after it reaches 100,000 kilometres, it’s essential to examine the service records carefully.

Regular maintenance and replacement of parts that are known to fail can significantly prolong the life of your car and prevent serious engine issues.

If you are considering buying a higher mileage BMW, make sure to look for service records. A well-documented history can be a significant advantage, showing that the car has been well maintained. This will also help you with resale.

Some BMW models have specific parts that commonly fail, so looking for one that has had these replaced is a good idea.

Cost Considerations

One thing to consider is that as your BMW gets older, serious repairs may be needed more often and can become quite expensive, especially with the engine or electrical systems. This is especially true for M models that have specific engines.

Deciding whether to continue repairing your BMW or to replace it can be difficult. In some cases, the cost of significant repairs could exceed the current market value of the car. This is an important factor to consider, especially when repairs become a regular need rather than a rare occurrence.

Additionally, consider the costs associated with parts and insurance. BMW parts are typically more expensive than other car brands and may not always be readily available, which adds to the overall cost. Insurance premiums can also be higher for hem.

It’s crucial to carefully consider these factors. A well-maintained BMW might still offer value, but you need to be ready for the potential financial impact of its upkeep as it gets older.

Recommendations For Buying a Second-Hand BMW

When you’re considering a second-hand BMW, it’s crucial to examine the car carefully for any signs of wear or significant repairs, especially if it’s done over 100,000 kilometres.

It pays to research the specific model that you are wanting to buy to find out the particular flaws it may have.

In some cases, buying a higher mileage car can actually be a good thing, because the common failure items will have been replaced.

Knowing this will help you buy a car that is less likely to give you problems.

Conclusion

BMWs can indeed be reliable after 100,000 kilometres, but you should look for one that has been properly maintained.

Always check the service history and consider the costs of ownership before buying. Also research the specific model to know what to look for.
