BMW weld seam of the integrated transmission control unit's cover may not have been manufactured properly, which could allow automatic transmission oil to leak into the transmission control unit.
The short version
BMW of North America, LLC reported a problem with the automatic transmission control module (tcm/pcm/tecm). Here is what owners need to know.
The weld seam of the integrated transmission control unit's cover may not have been manufactured properly, which could allow automatic transmission oil to leak into the transmission control unit.
Transmission oil that leaks into the control unit can lead to a seizure of the transmission gears, causing a sudden loss of drive power and increasing the risk of a crash.
Take it to a dealer — they will replace the transmission mechatronics module and the automatic transmission fluid, as necessary, free of charge.
