Hey guys.
2004 BMW Z4 3.0i w/ SMG Transmission. Currently in limp mode and have the following codes. All hard coded, nothing can be cleared.
Back story: I got the SMG Pump replaced TWICE. The first time around the pump worked, no codes. But then the pump failed. Second time around, with a brand new pump again. No codes, drove for a day. The next day, INTERMITTENT limp mode. The next day, stuck in limp mode.
OFTEN, 1st gear would throw me into Reverse - SCARY when taking off on a green light
Maybe it was not flashed/re-taught properly? Alternator? Regulator? TCM? Battery?
I've had the battery tested, and replaced twice with new batteries.
IF it is the alternator/regulator, please visit my other thread:
