2.5si rough running & engine light

[thorpyuk]

Hi all,
Jumped in the car this evening to come home & on starting the engine noticed that the car was vibrating slightly.
I pulled off and the vibration got slightly worse with the revs, and the check engine light came on. Turning the engine off and on again doesn't help either.
It doesn't seem rough enough to be down a cylinder, and I managed to limp her home. Does anyone have any ideas? Anyone had anything similar?
Thanks guys :/

Coil pack?

A simple hook up to a diagnostics coder will tell you for sure...

Thanks woody, i'm getting it checked out tomorrow. The symptoms do indeed sound like a coil pack just like this topic - http://z4-forum.com/forum/viewtopic.php?f=3&t=23790

Should i have them all changed? Someone in the topic above seems to suggest that there's some sort of service bulletin about changing the packs - anyone shed any light on that?

Should i get all the plugs changed too? Car is on 75k miles...

Diagnostics came back with 'Misfire number 4 cylendar' - anyone know which direction they go? Does indeed sound like a coil...

That's good then, a cheap fix

Coil replaced & all fine Have ordered myself a D900 code reader - looks like a sound investment for the money!
