Troubleshooting BMW Drivetrain Malfunction Drive Moderately Warning

At our garage, we help car owners diagnose BMW vehicles that show drivetrain malfunction on the instrument cluster, and in this guide, we go over common issues that can cause this warning. If your BMW is showing drivetrain malfunction, don’t panic! Drivetrain malfunction means BMW is having a problem with either the transmission, driveshaft, or differentials. One of the most common causes of drivetrain malfunction is due to the 12-volt vehicle battery being too old and no longer holding a charge, so before you do anything else, check the vehicle battery first. If a new battery doesn’t fix the issue, you need to look at various issues, such as low transmission fluid levels, a faulty transmission control module, or a problem with the differential. We will also show you how to use the YOUCANIC full system scanner to diagnose the specific cause of the malfunction as soon as possible, as driving the vehicle with a malfunctioning drivetrain can cause further damage and make the repair more expensive.


Fix Drivetrain Malfunction on BMW

BMW drivetrain malfunctioning message indicates a drivetrain problem that can be triggered by something as simple as a weak car battery. This error is detected by the Engine Control Module – also known as Digital Motor Electronics – DME. To fix drivetrain malfunction try this: Park in a safe spot, turn off the engine, and wait for five minutes with the ignition turned off. You can take this a step further and disconnect the battery negative terminal. Do not keep any lights, cooling fan, or radio on during this time. In many cases restarting the car or disconnecting the battery will clear the error and allow you to drive the car again. If you restart the engine and the transmission has already switched to limp mode, you can carefully drive the car to a repair shop or home but keep in mind that the maximum speed will be limited to 40 mph. Be cautious while driving, as the malfunction may recur or cause additional issues.

BMW Drivetrain Malfunction Common Causes

As mentioned earlier, one of the most common causes that we see triggering BMW drivetrain malfunction is due to a weak 12-volt battery that may need to be replaced with the second most common being an engine misfire, typically caused by a bad spark plug or ignition coil.

Drivetrain Malfunction message on BMWs may appear:

  • under heavy acceleration,
  • going up on a steep incline,
  • taking off from a stop sign,
  • trying to pass another car,
  • when you first the engine,
  • when it is extremely cold outside.

Drivetrain Malfunction Drive Moderately can show up any time as you drive or at start-up but is more likely to pop up during cold weather if you have an old battery or come on under extreme driving conditions.

Driving is not recommended if the engine is shaking and there is reduced power or limp mode. Call your dealer or mechanic. Do not ignore a drivetrain malfunction warning. Get the BMW serviced as soon as possible. Even if the drivetrain error disappears, you should still have your BMW diagnosed, as it is highly likely to return.

Most Likely Causes of BMW Drivetrain Malfunction

Drivetrain malfunction warnings can come up for several reasons, from a weak battery to an engine misfire. Most likely, your issue will be due to one of the issues below. We strongly recommend getting your BMW diagnosed by a mechanic or, at a minimum, reading the fault codes yourself before you start replacing any parts.

1. Spark Plugs

Worn spark plugs are often the cause of drivetrain malfunction in BMW vehicles. When you change the spark plugs, replace all of them simultaneously.

2. Ignition Coils

Ignition Coils

A failed ignition coil can cause engine misfire and BMW error message drivetrain malfunction on iDrive.

If you are getting a cylinder misfire for one particular cylinder, there is a chance that the ignition coil to that cylinder is defective. Let’s say you get cylinder one misfire.

Swap the ignition coils for cylinder one and cylinder 2. Clean the codes with an OBD-II scanner. Run the car until the check engine light comes back on. You have a bad ignition coil if the code moves with the coil.

3. High-Pressure Fuel Pump

HPFP

BMW drivetrain malfunction can also be caused by a fuel pump that does not generate the required fuel pressure, especially if the error message is coming up when accelerating.

The fuel pump may fail to create enough pressure, especially when there is a high demand from the engine.

4. Catalytic Converter

Catalytic Convert

A clogged catalytic converter can also cause a BMW drivetrain malfunction error message.

Catalytic converter failure is more likely to happen in high-mileage vehicles where the catalytic converter clogs and restricts the exhaust gases.

5. Low-Quality Fuel or Octane Rating

Catalytic Convert

This problem can be caused if you recently filled the car with low-octane gasoline. Use premium gas on your BMW, 93 or higher octane. If you accidentally used a low octane, consider adding an Octane Booster to the fuel tank to increase the octane level of the gasoline.

6. Clogged Fuel Injectors

One or more damaged fuel injectors can cause BMW to drive with moderately reduced power. If your mechanic determines that the fuel injectors are faulty, replacing them simultaneously is recommended (but not required).

Other possible causes of BMW drivetrain malfunction include a blown head gasket, mass airflow sensor, turbo issue, and fuel injectors. While it is impossible to know what caused the BMW drivetrain to malfunction in your car without reading the codes, this error is due to an engine misfire in most cases.

Conclusion

BMW Drivetrain Malfunction Drive Moderately

BMW drivetrain malfunction on a BMW can come up for a number of reasons ranging from a weak 12-volt battery to a faulty high-pressure fuel pump. Sometimes drivetrain malfunction is due to a simple software glitch in the DME that will reset by simply disconnecting the battery for a few minutes and restarting the engine, other times the vehicle needs to be repaired to clear the drivetrain malfunction drive moderately permanently. Use a full system scanner to run a full diagnostic check on the vehicle to find out what is causing the drivetrain malfunction on your BMW.

  1. I have a 2017 328D and had the Drive Moderately Maximum drivetrain output not available. Consult the service center notification come on. 78K miles on the car. I noticed that it would come on at around 200 ft pounds of torque. It would clear on its own after a bit. After a day of this, I noticed the check engine light came on and stayed on. The drivetrain notification would come and go. The car rode fine. Was able to do whatever speed I wanted. With the engine light staying lit and the notification coming and going, after a few days I brought it to the dealer. Here is what they found:

    HOOKED UP BATTERY CHARGER AND PERFORMED VEHICLE TEST. FOUND FC# 244C00 CHARGING PRESSURE CONTROL CHARGING PRESSURE TOO LOW, FC# 244D00 CHARGING PRESSURE CONTROL CHARGING PRESSURE TOO HIGH, FC# 25CE00 CHARGING PRESSURE SENSOR SIGNAL TOO HIGH, FC# 290900 AIR MASS SYSTEM MEASURED AIR MASS TOO HIGH AND FC# 25D400 EXHAUST BACK PRESSURE SENSOR BEFORE TURBO CHARGER SIGNAL TOO HIGH. PERFORMED INSPECTION OF TURBO CHARGER AND FOUND CONTROL ROD FOR WASTE GATE MISSING. REMOVED LOWER ENGINE SPLASH PANELS AND FOUND MISSING CONTROL ROD. DETERMINED CLIPS FOR CONTROL ROD HAS BROKEN AND CLIP FELL OFF. RECOMMEND TO RE-INSTALL CONTROL ROD AND SECURE WITH CLIPS TO START.

    Essentially the control rod between the turbo and waste gate fell off as the retaining clips broke. Luckily the tech found the control rod on splash panels. That control rod and clips cannot be ordered. They would have had to order a turbo. He was able to source c-clips to hold the control rod onto the shafts. $577 later all is good!!!! Could only imagine what the cost of a turbo would have been.

    I have a 2015 BMW 320i and last week on the freeway the car message came up drivetrain malfunction, drive moderately. I drove it home slowly and I have not taken it to BMW dealer yet but a mechanic told me that I need a new turbocharger for the car, is that true? does that message mean I need a new turbocharger? no check engine light came up and when I got home and parked the car for a while the message disappeared.

    1. It’s fine sometime the car senses things that aren’t dangerous and gives you the message, even if the message persists sometimes it’s very minor and just needs to be reset.

    I have a 650I w/53700 miles on it. My warming about the Drivetrain Malfunction happen yesterday. I immediately drove to and dropped the car at the dealer.

    My question: BMW just pulled my engine less that 4000 miles ago. There was a recall to do a valve job on the car. In order to do the recall work my engine needed to be removed. Could that be in relation to this drivetrain malfunction now? I find it odd that this is happening pretty close to the major recall work. Please advise me on your thoughts.

    I had this exact problem and it went on for about 1 year beginning about 75,000 which was 300 miles after the warranty ended. I have a 2014 BMW X3 and I got stranded on the freeway, towed it to BMW and they had the car for 3 weeks. Replaced the spark plugs and 1/2 of the fuel injectors. Got it back and in less than 12 hours, I was stranded again, same problem. Towed back to the dealer who replaced the rest of the fuel injectors and the coils. It was fine for a year and then I received the drive train malfunction error multiple times over 3 months but the warning would come on sporadically and then the warning would randomly go off.

    This time I took it to my BMW mechanic (not the dealer), and he tested and replaced the battery because it failed all tests – seriously in a 4 year old car… Got it back and the drivetrain malfunction came on again, this time as I was going out of town on a long road trip. Back to the mechanic and this time they worked on troublehooting with BMW and they figured out that it was the turbo waste gate. Replaced the part and it runs like a top. Too bad, it took so long to figure this out.

    This car has been a huge disappointment and I’ve been a BMW owner for 20 years. Ask your mechanic to check the turbo waste gate before you do all of the other expensive repairs.

    I recently got an oil leak fixed on my BMW 535i which required the mechanic to remove a lot of parts from under the hood. After the oil leak was fixed I got an error message: DRIVETRAIN MALFUNCTION: DRIVE MODERATELY. MAXIMUM DRIVETRAIN OUTPUT NOT AVAILABLE. CONSULT SERVICE CENTER.
    This occurs every time I accelerate to pass another car or accelerate on the freeway. This error NEVER happened prior to getting the oil leak fixed. I am concerned that the mechanic may have forgotten to connect something or knocked a sensor out of place. The error comes and goes and I do not have any shaking or anything. The car drives normal.

    Hello, I recently installed a high flow catted down pipe (200 cell), a charge pipe, an intercooler, and a jb4 tune . Now every time I drive the car for more than 5 minutes I get the “Drivetrain malfunction: drive moderately. Maximum drivetrain output not available. Consult service center”. I am wondering if this is most likely because of the downpipe installed or if I need to upgrade my spark plugs for the higher power the engine is now making?
