How To Fix Drivetrain Malfunction On BMW

BMW is an ultimate performance machine, which gives an unforgettable experience while long driving. But, as with any other car the BMW also faces some issues, and one of them is the drivetrain malfunction.

The drivetrain is an important system in a vehicle, which transfers the engine power to the wheel. This Drivetrain Malfunction error indicates any malfunction in the drivetrain or on any related component.

If you have also encountered the same issue don’t worry, I’ve got you, in this guide we’ll discuss all the symptoms, causes, and potential fixes.

What is a Drivetrain Malfunction On BMW?

As described above the drivetrain malfunction is the simple indication that the Engine Control Module (ECM) identifies there is something wrong in the drivetrain system or any component related to this system.

Causes of BMW drivetrain malfunctioning?

There can be many causes that will eventually lead to the drivetrain malfunctioning, starting from the spark plug and fuel injector to low-quality fuel. Here are the most common causes of the drivetrain malfunctioning:-

  • Faulty Spark Plug
  • Ignition Coil malfunction
  • Fuel Pump Issue
  • Clogged Catalytic converter
  • Fuel Injector Issue
  • Using Low-Quality Fuel

Everyone’s vehicle has driving & maintenance conditions, which can cause different reasons for different malfunctioning. Above are the most common issues for this error, but you could have different causes for your vehicle so it’s better to get your vehicle diagnosed before processing the fix.

After seeing the drivetrain malfunction error you should fix this problem as soon as possible, cause otherwise this can further damage the performance and safety of the vehicle. So, now let’s discuss the process to fix the drivetrain malfunction on your BMW.

To fix this malfunction there are two ways to do that first to do it yourself(DIY) and seek professional help. So, first, let’s discuss about the DIY process.

1. Identifying The Warning Errors

Before fixing any problem you should first know that there’s any problem exists. BMW is equipped with one of the best diagnostics systems, which find out any major and minor problems.

To identify the drivetrain malfunction you should check for the drivetrain malfunction error on the dashboard, where a drivetrain malfunction warning or check engine light will show up.

You will also experience poor performance, unnecessary vibrations, and noises, which can be signs of this error.

2. Troubleshooting BMW Engine

While driving if you suddenly get a pop-up showing a drivetrain malfunction error, then try to do a troubleshooting the engine.

To do that, turn off the engine and let the engine set off for 5-10 minutes, then turn on the engine to see if the drivetrain malfunction error is resolved. Sometimes the software can show the wrong error, but after a quick troubleshooting, it should be fine. However, if the error still persists then do the next following steps.

3. Scanning the Fault Codes

The BMW uses an advanced diagnostic system, which identifies and shows any malfunction codes. By using an OBD-II scanner we can easily retrieve the fault codes and know the root cause behind the drivetrain malfunction error.

These codes can give valuable information about the specific problems. If the scanner can catch the code and give a specific reason for the error, then you can simply replace the component on your own or you can have any professional do it for you.

In the car, the DME (Digital motor electronic) stores all the codes for the engine, and the EGS(Electronic gearbox)/AGS(Adaptive gearbox)stores transmission codes. To use the scanner follow the step-by-step process:-

  1. First find out the OBD-II diagnostic port, which is located under the dashboard on the driver’s side.
  2. Now plug in the scanner, and turn on the ignition, but don’t turn the engine.
  3. Now this will connect the scanner with the vehicle, you can choose your vehicle model & select the DME & EGS/AGS for the codes.
  4. Now you can read the codes & get the specific information about the error.
  5. If you’ve got the reason behind the malfunction, you can now simply replace the component.
  6. After replacing the component restart your vehicle and with the OBD-II scanner remove the error.

But, if you can’t identify any issue with this step then read along, I’m going to show you another way to figure out the problem.

4. Transmission Fluid Checking

The drivetrain issue can occur because of a low level of transmission fluid. First, locate the transmission fluid dipstick near the engine, then check if the fluid is on the appropriate level and not dirty or cloudy.

If the fluid is low and dirty you have to replace the fluid, then check if the error is solved.

5. Update the Engine Control Module (ECM)

The ECM is a very important component in your vehicle, which controls the drivetrain system.

Any problem in the ECM can lead to drivetrain malfunction, so the ECM should be up to date to prevent this type of issue.

If the fault codes discover an issue with the ECM, then it should be reprogrammed or replaced.

6. Inspect For Any Leaks

You should also inspect for leaks, it can also be an indicator for the drivetrain malfunction. Mainly if any leakage occurs on the drivetrain system it will show a drivetrain error.

So, you should check under the vehicle for any fluid leakage, this basically occurs on the transmission, axle, differential, etc.

If you find any leakage you should replace the part as soon as possible to further damage the vehicle, and it will eventually correct the drivetrain malfunction issue.

7. Fill Quality Fuel

The drivetrain issue can also occur when you use low-quality fuel for a long time, which results in power loss in the vehicle. You should always use high-octane fuel to maintain/better your engine performance and stay away from the drivetrain malfunction issue.

High-quality fuel helps the engine to perform more smoothly and efficiently, maintaining the engine’s performance and reliability.

So, always opt for quality fuel rather than cheap low-quality fuel, it’s gonna save you money in the long run.

8. Check Transmission and Clutch

Transmission is an important component of the drivetrain system, so check for any hesitation, or roughness while shifting gears. Then it indicates any issue with the transmission or clutch.

If it is the situation you need to fix or replace the necessary component.

Seek Professional Help

Now if you’re not a DIY guy, and don’t have the time to diagnose & fix your vehicle, then you should absolutely seek professional help.

While some drivetrain malfunctions can be fixed by some of you DIY enthusiasts, some issues need the expertise of a professional technician. You may be unable to find or fix the drivetrain malfunction, in this case, you should contact your nearby BMW dealer or any trusted auto shop.

The professional auto shops have specialized tools and scanners which is used to do a full vehicle diagnosis, and they will identify the exact cause of the error.
