    A4 2.0TDI, Studder, won't ride propperly, electrical problem.

    Hello Guys and Girls.

    Lately we have been experience some kind of problems with my fathers Audi, after we swtich to wintertyres we have been experience some problems with the car.
    The the car is a 2.0TDI 2014 with 200 000 km (120 000 miles) on it.
    It all started when i had it for a spinn while i didn't have a car, after a houre or so riding i came out from a round about and while i tried to accselerate the car just vibrated and slowly gained speed, the whole car studders away in "limp mode". Stopped and went out of the car looking for something obvious fault without any luck. Swtiched the ignition on and started the car, was preapering for a uncomfortable ride home, but the fault was gone and it ran like a dream again. After some time my father called me and told me once again the car was misbehaving, stopped over to the side of the road and switched the ignition off and on, bang problem solved for a while.

    third time the sharm, after riding 200 meter to the main road we started noticing it one again, the peadale to the metal and the vibration came back, the car stalls, vibration, no warning in the dash, try to switch the esp off without any luck. My first thought was that the car think it's slides and the esp tries to stopped it.
    Connected the VCDS and only fault came up was a thaillight, fault var over 1 yeard old, checked the taillight was working and deleted the code.

    Now it happends once again, my dad road up to the cabin, on the slimey winter roads the car starts messing with us unce again. when we arived home i searched the car for fault codes is a ABS code, maybe this is the problem ? and a streering assistiance code ?

    I wonderd if the battery was wornout so i checked the status of it, the morning after we parked the car the VCDS read 11.8V and 29ah, tok the car for a 45 min spinn and when i came back i read 12.5V volt and 49ah.


    I wonder if anybody have an ide of what is causing this problem ?
    It's giving me a headace, google the fault codes, syntoms, and cracking my head for a cause of this problem...

    I tried to read the wheel speed aswell wondering if maybe a abs sensor is the cause of the problem. they all read the same, and it seems like they read steady. tried on a long staight, with the cruse controlled inn. They all showed the same, no "flicking" or anything.


    Best regards RkM2

    The studdering reminds me a lot of what we were experiencing when a spark plug coil went bad. But this caused a check engine light for misfires.

    The car in question is a disel without sparksplugg, it's unfortunately not the sinner in this case.
    It's no faults for the engine, and since the car 99,9% of the time run perfect i think it's something electrical. Unfortunalely...

    The battery definitely doesnt look right, 11.9v is not a good voltage to have. Thou, that should not really affect the way the engine runs. I also have the 2.0TDI and I've seen it run strange a couple of times, but also no errors recorded so .... no clue. Start with checking if you actually need a new battery, the B8 2.0 TDI is prone to wiring issues in the engine bay, if you dont have around 14v at the battery when the car runs... you have a problem there.

    Do you have verified the battery aging at 19-gateway Channel?
    It's strange. Electrical power is stable when car is running? Alternator issue?

    Your battery might be just fine, my bet is on the fuel regulator valve on the HPFP and the fuel regulator valve on the rail, this is what I have changed on my side and the shudder went away. Start with the High Pressure fuel pump regulator first. These are known to have issues but not throw any errors, you will get an error when the part starts to totally wrong.

    Tineo: yess i verified the at gateway ch 19, the battery seems stable when the car runs, but the power drops quicly when the engine is shut down.
    Maybe the battery is fine, just got my head spinning when i saw it showed 11.8-12 volts.

    Andyzaharia: tank you, i will defently look at the High pressure fuel pump and fuel regulator valve and see is this is the problem.

    Give you a update
