A transmission malfunction error code came on in my car.
Hello. You will need to know if your BMW appears to be running normally, or if there are noticeable problems. If there are problems, take it immediately to a qualified technician to diagnose before more damage can happen. Regardless, you should have the OBD II scanned, and then reset the fault codes. Then drive the vehicle again to see if the fault code comes back. If it comes back, have a qualified transmission specialist diagnose it further. If the code does not come back and the vehicle seems to run normally, then a transmission sensor may have momentarily read something out of parameter, and now shows normal operation.
