    :think:Hello everybody. I have an audi S3 2000 model, i want to know if fitting a Forge splitter dump valve can affect the the boost on the car for example on acceleration, experiencing a jerking like taking your foot on and off the pedal quickly. As iv been told my coil packs seem ok its the only other thing that has recently been fitted to the car that was not standard.

    Could also be leaking boost hoses, a dodgy spark plug, N75 valve, N249 Valve. fuel pump etc etc.

    You'd be best to get your error codes read. Find a friendly VAG specialist.

    Have you still got your original recirc valve? You coul run with that for a while and see if the fault still occcurs.

    If the fault is happening all the time, try disconnecting the MAF and running the car you a couple of miles. If the problem disappears, there's your problem
