Hi good people,
First of all, am a new joiner here and i hope I will find solutions to the issues am currently facing.
I did an engine swap from B8 with engine code CDNC to CDND after my previous engine seized few months after rebuild. I only swapped the motor and kept the old ECU, old Harness, and the crankshaft position sensor. The engine run well for few days and now had the OBD Code Fault p072600, and sometimes p179F00 or p17D800, Torque Limitation Due to Clutch Temperature. I didnt have these fault codes before. Sometimes, the motor just stops, and cant engage the gear. Stuck on neutral/parking.
I have tried to swap the harness to use the one that came with the CDND motor, but that dont seem to work on my old ECU.
My question is, could it be that the CDNC speed sensor with 2 pin and the new motor, CDND, are not compatible? Am I looking into getting a new CDND ECU just to make this work? Or can a software update of the old ECU solve this? Anyone who has this knowledge or has done the swap, kindly help. I will appreciate
