Resetting Drivetrain Malfunction on BMW

If you own a BMW, chances are high that you have come across the ‘drivetrain malfunction’ warning. This warning appears when there is an issue with the engine, transmission, or any other part of your car’s drivetrain.

The presence of this warning light can cause immense stress and panic among drivers. Fortunately, it is possible to reset the drivetrain malfunction warning without visiting a mechanic. In this article, we will discuss various ways to reset the drivetrain malfunction warning on your BMW.

Check Engine Light Reset

Troubleshooting/checking the check engine light can be crucial in resetting the drivetrain error code on your BMW. Check for any codes stored in the OBD (On-Board Diagnostic) system, if present. The OBD-II system generates these trouble codes whenever it detects a problem in the vehicle. You can use a diagnostic scanner to access the OBD-II system and read codes generated by the car. A few popular examples include BlueDriver Bluetooth Professional OBDII Scan Tool, Autel MaxiCOM MK808TS Diagnostic Scanner, Innova 3100j CanOBD2 Diagnostic Tool, etc.

If the codes reflect issues with drive train sensors such as mass airflow, crankshaft position /camshaft position sensor, oxygen sensor, temperature sensor, fuel injector circuit, etc., then resetting the check engine light may clear the drivetrain malfunction errors from storage as well. There must not be any active/faulty-code if you want to attempt an ECU (Engine Control Unit) reprogramming/replacement.

Resetting the Transmission Control Module(TCM)

The TCM controls the automatic transmission system’s gear shift function and also feeds essential information for the operation of the Analytical Dynamic Engine Control module (DME/ECU). Sometimes resetting the TCM may clear drivetrain malfunction codes from storage especially in following scenarios;

• Transmission sensor calibration errors may cause improper function of gears.
• Electrical connectivity faults between the transmission and DME due to poor wiring, loose harnesses, or corroded pins can cause transmission errors, which eventually affect other engine subsystems.

To reset the TCM, turn off the ignition and remove the key completely for at least 30 seconds. After the time has passed, reconnect the battery using the negative cable. This will allow enough time for the capacitors inside the control module to discharge fully for clearing any logged error codes/miscommunications.

Reprogramming the ECU

The Engine Control Unit is responsible for controlling various systems like fuel injection, throttle response, and the charging system. When there are issues with this component, it often leads to drive train malfunction warnings on your BMW vehicle. It’s best if you have verified that the issue isn’t something wrong with a fixable component such as spark plugs, air filter, etc., before attempting an ECU replacement job yourself.

You must always consult with a manufacturer-authorized mechanic/dealer center when replacing or reprogramming an ECU; all settings & configurations must be carried out strictly according to manufacturer specifications, equipment/software programmers updates, and safety protocols full of cautionary programming precautions. Any wrong-doing while proceeding with ECU repair can cause complex system errors.

Resetting the Battery

An easy way to reset most vehicle electronic components without any specific scanner tool needed is by disconnecting /isolating the car’s battery cables for some time. If none of the above works, try resetting your BMW’s battery by following the steps outlined below:

• Start by turning off all electrical components in your vehicle like radio, air conditioner, etc.
• Open the hood and locate the negative terminal/disconnect first cable from it. Then move over to the positive cable only if required delicately troubleshoot certain issues e.g., a malfunctioned ECU module or onboard computers that gets permanently deleted due to continuous power consumption.e
• Leave both cables disconnected for around 30 minutes before reconnecting them back.

When you connect the battery back up after this, the drivetrain warning light should no longer appear on the dashboard of your BMW. But if the underlying issue still persists, resetting these temporary solutions can just make the problem reoccur again rather than solving anything and cause an expensive repair job instead.

“Modern cars are akin to rolling computers, and the same way malware infects laptops and desktop systems is also possible inside your car.”

If you’re unable to reset any of these modules; it’s crucial access codes/code-readings that will help identify specific devices/settings affecting drivetrain configurations through OBD2 scanner tools/external diagnostic services – DON’T RESTORE your Bimmer using traditional procedures well described on general public forums/posts with non-OEM/SMS parts or softwares.

Preventative Measures to Avoid Drivetrain Malfunction

Drivetrain malfunction in your BMW can be frustrating and costly. However, it’s possible to avoid such issues with regular maintenance checks, proper driving habits, using high-quality parts and fluids, and timely oil changes. Here are some effective preventative measures you can take:

Regular Maintenance Checks

Regular maintenance is critical for avoiding car problems, including drivetrain malfunction. It involves checking various components of the vehicle regularly to ensure that everything is working optimally. Check the belts, hoses, spark plugs, air filters, fuel filters, battery, ignition system, and other systems according to your BMW owner’s manual or as recommended by a certified technician.

Avoid ignoring warning signs like odd noises, decreased performance levels, and burning smells that indicate an issue with your engine or transmission. Fix any defects early on before they become major, expensive problems. Schedule professional maintenance checks religiously if you’re unsure about how to go about the checks yourself.

Regular Oil Changes

Your BMW needs clean oil flowing through its engine to prevent damage and minimize wear. Dirty oil and clogged filters lead to faster breakdowns and drivetrain malfunctions. Aim to change your motor oil every 5,000 miles or six months, whichever comes first, depending on your BMW model and usage frequency.

Better yet, adopt synthetic oils instead of conventional ones, especially for newer BMW models. Synthetic oils’ advanced properties provide better protection and corrosion prevention. They also handle higher temperatures and pressures than traditional oil blends.

Using High-Quality Parts and Fluids

The quality of the replacement parts and fluids plays a significant role in preventing drivetrain malfunction. Using low-quality aftermarket parts compromises your BMW’s reliability and durability. They may not fit correctly, erode quickly, or cause leaks if you’re lucky.

Invest in OEM parts that provide the same quality, function, and safety as the original components. Remember to use recommended fluids and lubricants from reputable manufacturers. Cheap substitutes can contain impurities and have less resistance to heat and friction than premium products, leading to malfunction problems.

Proper Driving Habits

The most immediate solution for avoiding drivetrain malfunction is practicing safe and consistent driving habits. Avoid sudden acceleration, jerky stops, whip-around cornering, and inconsistent speed changes. Sudden movements impact your BMW’s transmission and engine systems’ performance—the more abrupt they are, the more significant damage it causes.

Keep your vehicle up to speed but don’t exceed its limits. Don’t overwork your car with heavy loads beyond its payload capacity, and avoid towing too much weight unless your BMW model supports it. Additionally, observe your BMW’s shift patterns according to how fast or slow you drive; this ensures no undue stress is placed on the drivetrain (transmission, clutch, and differential).
