Identify the Cause of the Problem

If your BMW is displaying a drivetrain malfunction warning, it’s essential to identify the root cause of the problem. The drivetrain has an extensive system that includes various components such as the transmission, engine, and exhaust. A problem in any of these parts can trigger this error on your dashboard.

The following steps will help you diagnose the source of the problem effectively:

Check for Error Codes

The first step in identifying the underlying issue is to check if there are any error codes saved in the onboard diagnostic system (OBD-II). These error codes contain valuable information about the specific part of the drivetrain affected, making troubleshooting easier and more accurate.

  • You’ll need an OBD-II scanner to retrieve the codes from your vehicle. If you don’t have one, borrow or rent one from a local auto shop or purchase one online.
  • Connect the scanner to your car’s OBD-II port beneath the dashboard and switch on the ignition but refrain from starting the engine.
  • The scanner should display a list of error codes and their definitions. Write down or take a photo of the codes displayed.

Listen for Unusual Sounds

Unusual sounds coming from your engine or exhaust could indicate a serious drivetrain malfunction. Such noises include whirring, grinding, knocking, or buzzing sounds. The type and intensity of sound may help pinpoint the exact location and nature of the problem. To listen for unusual sounds:

  • Turn off any music or noise inside the vehicle.
  • Talk someone who understands what sounds they may encounter.
  • Start the vehicle and let it idle while observing any unusual sounds.
  • Rev the engine and listen for any irregular sounds during acceleration or deceleration
  • If you identify any irregular noise, visit an auto shop as soon as possible to prevent further damage

Perform Visual Inspection

A visual inspection of your BMW will help identify any noticeable signs of wear, leaks, or damages. Here is how you can inspect your car visually:

  • Park the vehicle on a level surface away from direct sunlight
  • Open up the hood and check for oil levels, cooling fluid levels, and transmission fluid levels.
  • Inspect the exhaust pipes for visible cracks or leaks.
  • Check belts and hoses for wear and tear or any discolorations. Replace them if necessary.
  • Examine all electrical connections for corrosion and dirt buildup that may inhibit proper functioning
  • Look for loose bolts, screws, or nuts in the drivetrain. Tighten them appropriately but without excessive force.
“Regular maintenance and timely repairs are crucial in ensuring optimal performance and prolonging the life of your BMW.”

The above steps should give you a better understanding of what’s causing your drivetrain malfunction error message. Some issues, such as low tire pressure or a dirty air filter, can be easily resolved with basic maintenance techniques. However, more severe problems like failing transmissions or damaged engines demand professional intervention. Avoid ignoring this warning light, as it could lead to costly repairs down the line.

Check the Transmission Fluid Level

To clear drivetrain malfunction in your BMW, checking the transmission fluid level is an essential step. A lack of proper lubrication caused by insufficient or dirty transmission fluid can cause various issues such as gear slipping, rough shifting, delayed engagement and overheating. Checking the transmission fluid is a relatively simple process that you can do yourself without any specialized tools or experience.

Locate the Dipstick

The first thing you need to do is locate the dipstick. In most cases, the transmission dipstick on BMW models made between 1990 and 2014 can be found on the passenger side of the engine bay near the firewall. However, newer models after 2015 don’t have a traditional dipstick but instead come equipped with electronic sensors that monitor the fluid levels. So before proceeding, make sure whether your car has a traditional dipstick or not.

Inspect the Fluid Color and Consistency

Once you’ve located the dipstick, remove it and wipe it clean using a lint-free rag. Reinsert the stick fully back into the tube until it clicks into place, then remove it again to inspect the fluid. The colour of the fluid should be bright red or light pink for fresh supply and gradually darken over time due to use. If the fluid looks dark brown or blackish color, this could be an indication that it’s getting old and dirty, and its ability to protect vital components is diminishing. The consistency of the fluid also matters: good condition fluid will have a bit of texture to it and will feel slightly thicker than water whereas if it feels gritty or sticky, there may be contaminants present.

Check the Fluid Level

The next step is to check the fluid level itself. While holding the dipstick steady, note the two marks on it; typically one initial/full mark and a low or add mark. The level of fluid should be between these two markings, typically in the middle-range area of the dipstick. If the transmission level is below the minimum line, that indicates that your car needs more fluid.

Add or Replace Fluid as Needed

Adding fresh fluid to your BMW’s transmission system can sometimes be complicated, so unless you are comfortable doing it yourself, it’s best to bring your vehicle into an automotive professional who has experience with BMWs. When adding new fluid, make sure to use the right type of fluid that meets your car manufacturer’s recommended standards to avoid any future problems. If the fluid seems dirty when you check it or smells burnt, then it may need to be replaced entirely. Replacing your transmission fluid may need advanced skills or equipment, so consult less experienced technician for advice before performing such services.

Checking the transmission fluid level is a simple process, but often overlooked by many car owners. Keep your BMW’s drivetrain running smoothly by regularly checking and servicing your transmission system, using only quality fluids and taking appropriate measures if any problem arises. Proper maintenance will not only ensure longer lifespan and durability of parts but also prevent unnecessary repairs, costs, and inconvenience.

Reset the Drivetrain System

If you own a BMW, at some point you may experience problems with the drivetrain. It’s a complex system that includes the transmission, drive shafts, axles, and wheels. If there’s an issue with any of these components, your car’s computer will likely trigger a “Drivetrain Malfunction” error message on the dashboard.

This is understandably concerning for drivers, but fortunately, it’s usually a minor issue that can be easily fixed by resetting the drivetrain system. Here are some steps to follow:

Turn Off the Engine

The first thing you need to do when trying to clear the drivetrain malfunction on your BMW is to turn off the engine. Make sure everything is switched off and left inactive. Doing so allows the vehicle electronics to stabilize before moving forward with repairs.

Disconnect the Battery

After turning off the engine, disconnect the battery cable from the negative terminal as this helps break all automatic operations that aren’t discontinued with just switching off the engine.

“Removing the battery terminal will act like a ‘hard reboot’ of the car’s computer,” says Keith Barry,’s contributing writer

When you remove the battery, wait a few minutes before proceeding to reset the system allowing enough time for the memory capacitors to fully discharge. This would make sure there’s no residual power in the electrical circuits, giving the vehicle electronics the chance to restabilize itself.

Reconnect the Battery

Once you’ve waited long enough, reconnect the battery properly, then start the BMW engine. Doing so reboots most indications, including those related to little errors like changing interior bulbs or brakes pads wear reminders in older models.

Start the Engine and Test

If everything with the battery was done in order, restart your BMW engine. The car should not indicate any more drivetrain malfunction errors is the problem was fixed with the resets.

“Sometimes when computers have glitches, a hard reboot will resolve them,” says Dave Shapiro, Northeast sales director for DealerSocket, an automotive software company which provides websites and auto dealer services. “We’re doing the same thing here.”

Resetting the BMW drivetrain system is generally doable by anyone who follows the right procedures. If successful repair did not occur from this process, it can be a sign of something more severe beyond one’s endeavor to fix it resulted, and professional inspection is highly recommended.

Replace Faulty Sensors

If you own a BMW and are having drivetrain malfunction, it could be caused by a number of different reasons. One common cause is a faulty sensor. If your car’s computer detects an issue with one of its sensors, then it may trigger the drivetrain malfunction warning. To clear this warning, you’ll need to replace the faulty sensor. Here’s how:

Use Diagnostic Tools to Identify Faulty Sensors

The first step is to use diagnostic tools to identify which sensor is faulty. This can typically be done using OBD-II (On-Board Diagnostics) scanning tools. These tools connect to your car’s computer and read any error codes that have been generated. Once you’ve connected the tool, you can run a diagnosis and it will tell you which sensor is causing the issue.

It’s important to note that some sensors may not generate error codes. In these cases, you may need to use more advanced diagnostic techniques such as oscilloscopes or multimeters to test the sensors directly. Alternatively, you could take your car to a professional mechanic who has specialized equipment for diagnosing sensor issues.

Remove the Faulty Sensor

Once you’ve identified the faulty sensor, the next step is to remove it from your BMW. Before doing anything else, make sure you disconnect the battery to avoid any electrical shocks.

To remove the sensor, you’ll likely need to access it from underneath your car. Be sure to wear gloves and eye protection when working on your car to avoid injury. Depending on the location of the sensor, you may need to remove other components before you can get to it. Carefully follow any instructions in your car’s manual or repair guide for removing the sensor.

Install the Replacement Sensor

After you’ve removed the faulty sensor, it’s time to install a replacement. Make sure you have the correct part number for your car and order a new sensor from a reputable auto parts store.

To install the replacement sensor, simply reverse the steps you took to remove the old one. Carefully connect the wires and make sure everything is properly secured before turning your car back on. If you’re unsure about any step in the process, be sure to consult your BMW’s repair guide or take your car to a professional mechanic.

“Replacing sensors is straightforward, but the complexity of the actual work will depend on the sensor’s location.” –

By following these simple steps, you should be able to replace a faulty sensor and clear your drivetrain malfunction warning. However, keep in mind that there may be other causes of drivetrain malfunction as well. If replacing the sensor doesn’t solve the problem, then you’ll need to investigate further or take your car to a professional mechanic who can help diagnose and fix the issue.

Inspect the Wiring and Connections

Visually Inspect the Wiring and Connections

The first step in clearing a drivetrain malfunction on a BMW is to visually inspect the wiring and connections. You need to check for any visible damage, fraying, or corrosion in all the electrical components of your vehicle.

A good place to start is by checking the battery terminals. Corrosion can build up on the lead plates of the battery and prevent it from delivering adequate power to the engine. If you find any rust or buildup, use a wire brush to gently clean it out, allowing your car’s electrical system to do its job correctly.

Another crucial component to check is the ground connection. Ensure that this cable is securely fastened because a loose ground could cause several issues with your vehicle, including a drivetrain malfunction error code.

Test the Wires and Connections with a Multimeter

If everything looks good upon visual inspection, then it’s time to use a multimeter tool to test the wires’ continuity and ensure they’re carrying an electrical charge when they should be. A digital multimeter is an essential tool in automotive troubleshooting since it measures voltage, current flow, and resistance.

You’ll need to follow the user manual instructions to connect the normal probes into different points along the wiring path while the circuits are turned off. When testing for continuity, you’ll listen for the multimeter beep to determine whether there’s a break somewhere in the circuit.

If you get an initial reading, switch the meter to read direct current (DC) and take further measurements as necessary. Testing requires patience and careful measurement skills, but the right readings indicate that each piece of equipment is working, indicating which parts are faulty and need replacement.

“A circuit functions only when voltage passes through all wires, so continuity checks are an important step in any troubleshooting process.” -Tom Denton

Drivetrain malfunction can often be traced back to wiring problems and intermittent faults that occur gradually. Therefore, it’s imperative to check each cable connected during the inspection for wire rotting or breakages that might have been missed earlier.

If you notice any damage on your BMW’s wiring, replace these faulty parts since they may cause bigger issues down the line. If a new part is out of the question, try to find suitable spares to make repairs where possible.


Due diligence pays off when it comes to interpreting complex BMW error codes like drivetrain malfunctions. Thoroughly inspecting car components, wiring looms, and connectors that serve sensors and engine management software can help restore driveability and avoid unnecessary trips to the repair shop.

It’s important to note that not everyone feels comfortable working with electrical connections on their cars. Therefore, getting assistance from a qualified mechanic is not a bad idea. Trying to fix significant electric faults without knowing what you’re doing could lead to further harm than good, resulting in more costly repairs in the long run.
