Fault codes n20 328i
Hey,
Struggled to find anyone who has had this issue via google so thought I would ask here. Codes; - 420665 - 8044B0 What it could be? Everything works fine (paddle shifters, speed limiter, volume buttons, etc..). Tried to clear the fault codes and they appeared again after a few minutes. I have new agm (oem battery). What can I do next? |

Hey, I had the same problem and same error codes - which were a real mystery for me as shifters worked well. I've found out that it might be related to a clockspring wires or even FEM which are quite expensive in comparison to just puddles. Luckily after paddle shifters replacement codes are gone. I've cleared errors and tested it for a while everything works perfectly fine.
P.s. Airbag removal is a pain in the a** so if you've never did that and you want to try to change PSs prepare for a real battle. Good luck guys! |
