Thanks

Thanks for the advice I will look into it.

Not a bmw specialist but tells me he has computer to scan for faults, guess you are right though, probably best option, just thought someone else may have encountered this problem and know what it is.

I have a 1998 540i e39, it sometimes seems as though the ignition sticks when I try to start it, when this happens it will idle roughly for a little while then cut out, generally if I leave it for a bit it may start OK, then after driving for awhile (tonight about 15kms) it will backfire a number of times, the problem comes and goes, I have taken it to the mechanic twice and so far he has replaced one of the coils and the ignition, but still the problem is there. I recently purchased and used a srs light reset tool and the problem only seems to have cropped up after that, can anyone offer any advice?
