Im in the process of changing my spark plugs and ignition coils in my 06 323i and as I took the last one out it was filthy with what looked like rust. What would have caused this and should I clean the slot that it goes in I assume? What would be the best way to go about that?

cheers

Well, that's mighty odd, and I notice deposits all around the area. Something's evaporated there; I'm inclined to agree with 2NASpec - better check for coolant leak.

no coolant loss or any leaks as far as I can tell... just picked up the car a couple of weeks ago and it just started to have a rough idle and while at high rpm will sometimes give me a liitle hiccup and I can tell its missing some power. Will occasionally get a rotten egg smell but nothing really sweet. Also no smoke or steam from exhaust. With the rough idle I thought changing plugs and ignition coils would help but it didn't change a thing. I changed all 6 plugs and just the one ignition coil that was filthy. Should I have changed them all? I read something else in another forum saying it could be a faulty throttle body or valvetronic motor... any thoughts?
