Monkey Posted January 18, 2020 Share Posted January 18, 2020 Hi, I have a 2004 A6 Quattro S-Line,i am having a problem with the fault code P0252 Powertrain. injection pump fuel metering control 'A' range/performance(Cam/Rotor/Injector). the problem is sometimes the check engine light comes on,on the dash,no loss of power etc,get home check with OBD2 reader all ways same fault ,go to use the car later no check engine light,no fault codes,no problem starting/driving the car,could this be a faulty sensor somewhere ie injection pump.and are they replaceable or is it a new/refurb injector system.
