Hello,
I just bought a jeep patriot with Mercedes engine OM651 2.2. The engine is knocking very bad while accelerating. The performance is not so bad. I don't know the service history of the car.
Read Codes
P032600 /KNOCK SENSOR 1 CIRCUIT - PERFORMANCE
P032B00 /KNOCK SENSOR 3 CIRCUIT - PERFORMANCE
P0A5B00 /GENERATOR CURRENT SENSOR CIRCUIT - LOW
I believe is the timing chain a tooth wrong or chain tensioner.
OM651 chain is behind engine and must take out the engine to check.
Any ideas?
