WK2 Petrol Penstar Check Engine Light, Misfiring and Compression Fluating
I have a 13 petrol WK2 Jeep.
It’s has developed a check engine light.
The error code come back cylinder 1 misfire
Compression 40% lower on cylinder 1 and 3
Any ideas?
Coils, sparks, leads, electronic all checks out fine
Typical symptoms of early Pentastar left hand cylinder head problems, caused by burnt out valve seats.This problem was/has been fixed under warranty by FC.Notify your nearest dealer or FCA asap.Do your homework by googling this problem.
Is best to get it checked & if the same problem as the TSB ask if they will cover it.
Cylinder numbering as per the service manual is:
Left side (passenger side) of engine block from front to rear of engine 2,4,6
Right side (drivers side) of engine block from front to rear of engine 1,3,5
