2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 421



- Valve lifter Faulty



(Intake valve has not switched to the other lift or has not switched quickly enough)



- Mechanical fault Valve drive



- Compression too low



(e.g. Cylinder lining damaged, Valve-seat ring Faulty ...)



Fault setting condition(s) (See [Information])



- Diagnosis detects uneven running for the specified cylinder.



- Uneven running is calculated from the expected and actual crankshaft acceleration due to combustion.



- Uneven running is interpreted as a misfire or valve lift fault, depending on type.



INFORMATION



- It is possible that only one cylinder (or the cylinders of one bank) has/have exceeded the uneven running threshold for a fault entry.



- Other cylinders may be just below the level which would result in a fault entry.



- See Actual values:



- [M005_Rough running ...] ... [M080_Rough running ...]

P0326



Diagnosis information - Control unit DME (DFI)



Knock sensor 1



Diagnostic conditions



- Short test



or



- Engine running, at:



- Period since engine was started > 10 Second(s)



- Engine temperature > 50 锟斤拷C (锟斤拷F)



- Engine speed > 1,000 1/min



- different load ranges



Possible fault causes



- Loose contact or corrosion on connectors or lines



- Short circuit to ground or open circuit in lines



- Knock sensor 1 loose



- Knock sensor 1 Faulty



Fault setting condition(s)



- The fault is detected if the signal of the knock sensor changes insufficiently or is too weak (noise is >>quieter<< than expected).



Fault effects



- If the fault is stored, the ignition timing is retarded for all cylinders affecting this knock sensor in the >knock-control active< range.



- Knock control adaptation is idle.
