Misfire on cylinder 4.
Goes into MB who replace all 6 spark plugs.
Car returned, all is well for a few days.
Misfire returns.
Return car.
Further testing done. Coilpacks fine. Injectors fine.
Car returned with faults all cleared and car running as it should.
This was 2 weeks ago, car running absolutely fine until today.
Misfire has returned.
Car will go back on Monday.
In the mean time, any thoughts?
