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.

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.

When considering a BMW Z4, you’re choosing more than just a car; you’re opting for a blend of luxury and performance.

With the Z4, there are a number of things to look for to find the right model for your needs.

In this blog, we will cover all the different things you should look out for when looking to buy a BMW Z4.

Z4 Model Specifications and Options

The BMW Z4 offers a variety of engine choices to match different performance needs. Options include the 2.0-litre N46 four-cylinder engine and more powerful six-cylinder versions such as the 3.0-litre M54 and N52.

For increased performance, consider the sportier M models, which improve both handling and power.

Models updated after 2006 also bring new technology and a facelift, raising the overall driving experience.

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.

Suspension Wear

The Z4’s suspension, especially the rear suspension components like the control arms and bushings, can wear out prematurely. This can lead to uneven tire wear, poor handling, or clunking noises from the rear.

Electrical Issues

Some owners report issues with electrical systems, including the central locking, windows, and dashboard warning lights. This can be caused by aging wiring or faulty sensors.

HPFP (High-Pressure Fuel Pump) Failure

In models equipped with the turbocharged engine (particularly the N54 engine in earlier versions), the high-pressure fuel pump is known to fail, causing stalling or rough idling.

Vanos (Variable Valve Timing) Issues

The Z4 is also known for having problems with the Vanos system, especially in the earlier models. Symptoms include rough idling, power loss, and poor fuel economy.

ABS and DSC (Dynamic Stability Control) Failures

Some Z4 owners have reported issues with the ABS pump or DSC module, leading to the ABS warning light coming on and reduced braking performance.

Battery Drain

Due to electrical issues or parasitic drain, the battery in the Z4 can sometimes deplete faster than expected, leading to difficulties starting the car.

Conclusion

If you are considering buying a Z4, we can perform a pre-purchase car inspection for you to give you insight into it’s true condition.

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 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.

So you’ve got a BMW E46 M3, one of the most enjoyable drivers’ cars ever made. But to ensure your car runs well, you need the right engine oil.

There are many options available, from various brands to different grades, but only a few suit the specific needs of the BMW E46 M3.

So, which is the correct oil for your BMW E46 M3? Keep reading to find out.

BMW’s Recommended Oil for E46 M3

When it comes to your E46 M3s, you need to use a specific grade of engine oil in order to ensure the engine is maintained correctly.

The specific oil recommended by BMW for the E46 M3 is the Castrol TWS 10W-60.

BMW partnered with Castrol to make an oil specifically for their M engines, so it is crucial to use this exact oil on your M3 if you want to maintain it correctly.

It’s important to note that not any 10W-60 will do. This specific TWS oil has additional additives crucial for the M3s engine, so it must be the 10W-60 TWS oil.

Do You Have to Use This Specific Oil On the E46 M3?

The short answer is yes, if you want your engine to last.

These motors are made with much tighter tolerances and are under higher strain due to being high performance.

This oil was specifically designed for use in these motors to maintain them as long as possible in top condition.

If you use a different oil, whether it’s a different weight or contains different additives, you are risking increased wear on your engine.

If it’s time to service your E46 M3 and you want someone you can trust, give us a call today on 09 441 3635 or email us on service@dodsonmotorsport.com. We specialise in BMW Servicing in Auckland and will ensure your E46 M3 is serviced correctly with the right oils.

You’ve bought a high-performance car and naturally, you want it to stay in top shape. A vital part of this process is knowing when it needs servicing. 

In this blog, we will cover the service interval for the BMW M2 and the specific information you need to know about servicing your M2.

The Recommended BMW M2 Service Interval

The first service on the BMW M2 needs to be done after the “break-in” period of 2000 kilometres.

After that, the recommended service interval for the BMW M2 is once a year or every 15,000 kilometres, whichever comes first.

If you’re unsure about when your service intervals are due, you can check the manufacture date sticker inside the driver’s door. 

Remember, these intervals can vary depending on several factors including the type of driving.

Impact of Driving Style on Service Schedule

Your driving style can greatly influence how often your car needs servicing. 

Low stress driving with lots of highway cruising can extend the need for servicing, though it is still recommended to keep to the schedule mentioned earlier.

What you do need to make a note of is high stress driving, such as track days or regular spirited driving will require more regular servicing if you want to keep your engine in good condition.

Which Oil You Should Use On the BMW M2

The recommended oil for the BMW M2 is a 0W30, however, it must be an LL-01 or LL-01FE approved synthetic oil.

With a performance engine such as the M2’s, it’s even more important to use the correct grade oil in order to maintain it’s condition. So make sure you get the right oil if you are doing the oil change yourself.
