I recently completed A dct swap into my E90 n54 but have 2 codes that seem to be my last issue. the car is coded and the shifter works great but the trans is in limp mode due to 2 codes I assume because of wiring in the trans harness i had to re pinning my auto trans harness because At the time i didn’t have the 335is harness and attempted to make that auto harness work..
I successfully swapped over the Dsc module and Dsc sensor and coded that to the Car.
The swap came complete with shifter with all appropriate modules connectors, n55 dct trans, n55 dct diff etc..THE ONLY THING I DIDNT HAVE WAS THE HARNESS. which i did attempt to reppin my auto one but i think it’s causing the issue..
I went ahead and just bought a 335is harness and it arrived a day ago and am in the process of installing it. I’m hopping it was an incorrect wiring issue and that this OEM harness fixes my issue. I am in the process of installing the harness since i have to drop the trans to reach the connector.. I’m posting the codes that where present before the installation of 335is harness below... any insight is greatly appreciated..I don’t mind sharing contact info. I’m so close to completing the swap!!
