Evening, My 09 past was running ok, then i accelerated to overtake and the glow plug light flashed, car was ok.
I read the codes and got--
P0122 Throttle Position Sensor/Switch A Circuit Low Input
P2454 Diesel Particulate Filter Pressure Sensor A Circuit Low
P0607 VOLKSWAGEN - Control Module Performance
P0182 Fuel Temperature Sensor A Circuit Low Input
HELP!!
Could all of these be caused by the Fuel temp sensor being faulty?
Cars only done 68K, previous owner never drove the car hard,
Did all 4 codes come up on VCDS with the same date/ time/ mileage ?
If not I would clear them & see what returns.
Then try a similar manouver on a quiet road to see if the problem can be replicated.
All codes at the same time, i cleared them, but they came straight back on when i read them again
The P0607 VOLKSWAGEN - Control Module Performance refers to the ECU itself I think.
The other faults refer to low voltages.
I would start by checking your battery is ok, should be at least 12.5v & around 14v with the engine running.
Check all battery & earth connexions are clean & tight.
Then move to the ECU, check the multiplug connexion for any moisture or corrosion on the pins.
Have a look inside the ECU case & check for any moisture/ corrosion in there.
Flashing glow plug light suggests DPF issue.
There lies the problem.Quote:
