2011 C350 ODB2 reads misfirecylinder 3 check engine light on
We recently purchased a 2011 C350. The check engine light came on then went out after I checked fuel filler cap - likely co-incidence. Engine light back on, OBD2 code reads misfire cylinder 3. 58,000 miles on car, replaced plugs, also swapped coils between cylinder 1 & 3. Check engine light still on, still reads misfire cylinder 3.
Any thoughts? I will be taking car in for B service and thought I'd get some information beforehand.
Thanks. I like the information I see here, I use forums for information when working on my Boxster and I will be using this one going forward for my wife's MB.
I think maybe you have issues with fuel injection or direct injection??
