M5 misfire
Hi, my 2013 F10 M5 has an intermittent misfire. Luckily I have an extended warranty.
Its been to Ryebrook Worcester 5 times now. Its going back on 19th.
What should you expect them to do in terms of obvious work and i will ensure that they've done those things.
I know they have changed a coil and the ECU. I suspect they should change all coils and all plugs for starters?
Thanks
Max
