Hi all. I`ve had this problem with my car for a while. BMW took a loo at it and replaced a suspect DME relay but the problem still exists. Its going back to the dealership(M3 specialist) I got my car from, and from what I`ve told them so far they suspect the ECU is buggered. They will swap it with one from another M3 to see if it is that.

Question. Do I *NEED* to have a BMW M3 chip fitted, or can a superchip (or something similar) be dropped right in instead? Im not sure about doing this yet but if a superchip is 200 UKpounds and a BMW chip is 400 UKpounds I think I`d go for a superchip or something similar instead to get the extra bhp. Another part of me says I should keep it original and fit the BMW replacement part.


of course this is assuming it is the ecu that is the problem here.

Who's the dealer? I hope its not Munich Legends for your wallets sake. My Evo III had a misfire at 5,500 rpm. I got them to check it out during an inspection II. When I picked the car up they hadn't fixed it but moved the misfire up to 6,000 instead and introduced me to the driving delights of a sticking throttle (how kind!). After giving them 1,000 stg and being unable to trail throttle at 145mph on the M25 I decided to give Kevin Bird (Uxbridge) a chance. Okay, so he charges double the labour rate but he does know how to fix them.

PS I should have let the car max out but it was almost rush hour!!!
