Customer Question

I have a 2004 BMW 325I with the SMG transmission. The transmission warning light (!) comes on often. Normally after I reverse the warning light comes on when I attempt to shift into the D mode. I must then turn the car off and wait fir the light to go off before I can restart and proceed. Now I'm getting a service engine warning which is offering a code P0700.

hello, what question would you like answered about this?

Customer: replied 1 year ago.
What do you think the problem is? The smg pump and relay were replaced 1000 miles ago.

I think the problem is most likely a failed SMG control unit, or mechanical gearing issue

unfortunately the smg transmission cannot be diagnosed with a p code reader, so the actual BMW faults will need to be scanned and proper test plans run as suggested with a BMW factory scan tool or equivalent
