Component
POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM)
What Happened
Your vehicle's transmission control module, which helps the automatic transmission work properly, might have a problem with its cover. The cover might not have been made correctly, which could cause oil to leak into the module.
Risk if Unfixed
If oil leaks into the control unit, it can cause the transmission gears to seize, leading to a sudden loss of power and potentially increasing the risk of a crash.
Free Fix
You can have the transmission mechatronics module and fluid replaced for free at a dealership. You'll receive a letter with instructions, but you can also contact BMW customer service at 1-800-525-7417 for more information.
