    Jerky drive

    Hey guys

    My A3 idles fine when still, but if i drive off in 1st gear it feels very jerky, like if I accelerate a little bit it feels alot and if I lift off the accelerator it feels jerky again.

    The same for in 2nd gear too.

    Anyone got any ideas?

    Check and clean the MAF, Clean the Throttle body and check the connections to the Ignition Amp.

    That will more likely be a boost leak or broken pipe

    I get a similar code to the 2nd one, except mine shows too weak iirc
