I'm assuming that this code is caused by using a slightly different control unit with a different p/n. I've been searching for a used unit with an exact p/n match but haven't found one yet, so I might end up shelling out $560 to the stealer for a new ZAE control unit. What a PITA!
PM me the ZAE unit number you need. I may have one from my 95 325i that is the same.
