: Graham, If you take a few minutes and look through some of the posts on this board, you will see that Tim is here to help. You came seeking advice; he gave advice based on where the brains are on an E34 ('95 525i is under back seat, driver's left, at rear fuse panel). We don't know much about M3's here (nothing wrong with them, just not many owners of them here). Hope you found your answer. But don't jump all over us here. Nowhere do we claim to be ASE certified or factory-trained technicians; just people looking to save a buck like you. Good luck!
