Mini Cooper check engine light

Mini Cooper Code P1611

posted by Mark S.

This week a customer brought to us his 2005 Mini Cooper S with the check engine light on. Upon inspection we found code P1611. The transmission was in limp. P1611 which is defined as Serial communication w/transmission ecu. First thing we did was unplug the connector at the transmission and found that fluid had leaked through. We replaced the wire harness with a new one and cleared the code. Upon start up we attempted to engage the transmission into gear. Again the P1611 code came right back. Further research we found that the 5 amp fuse in the drivers kick panel marked f-13 was bad. The fuse also controls the reverse lights and transmission communication. Once we replaced the fuse all was well. Code gone and transmission shifts great.
