Ok, so e46fanatics is useless right now and can't find an answer to this...So car is throwing this code and my scanner comes up with "p1429 diagnostic module tank leakage heater malfunction"
I have searched and only found two threads on bimmerforums with no real answers. Any idea what is causing this and what the solution would be? One thread I found said could just be my gas cap being open? My cap isn't clicking when I close it, so i guess could someone also confirm if it does indeed click or not? Car has been parked all winter and I don't remember lol.
Thanks
