We've just made it 140 miles of trouble free motoring. The last 5 miles we got caught in a small traffic jam then off again. Now I've got a misfire and the engine light is flashing. I'm in rural Dorset so if anyone has got any comment I'd really appreciate it.

 

There's no overheating or other symptoms. When it's given some revs it goes OK (I checked if the brake servo hose hadn't popped off).

 

I did drive through a lot of surface water on the M3 but no suggestion of problems then. Just after we waited then pulled away again the misfire occurred.

You could try telling us what the fault code(s) are, rather than expecting us to be psychic.

I strongly suspect a failing coil pack if it's a BBZ engine.

Sadly being on holiday I have no reader or access to one. It's relaxing at home 🙄. I nearly packed it too...

Cheers. Do they need coding to the car or just replace? If coding is needed I'll order one and call at a garage. 

Just replace. Nothing to code.

Thanks Pete. On inspection the epoxy shows heat damage on all four. I've just ordered from Amazon and it will arrive tomorrow. I'll update here if it fixes it.

Ok quick update. My OBD2 reader arrived today and showed cylinder 3 misfire so fitted the new coil pack there. Hopefully this will solve the problem. 🤞

 

Thanks for the help.

Took it a good drive and went better than for a long time plus no misfire so coil pack confirmed 👍
