    You would have been better off replacing the N75 before you got a remap.

    I not sure if i need to replace the n75 or the DV valve i have log in to the vag.com and came this:

    17963 - Charge Pressure: Maximum Limit Exceeded

    It was runing well before went in to limp mode for 3 minutes then went back to normal
    I was driven at 50 mph :crying:

    I have both a perfectly working N75 valve (in fact I have two)... and an atmospheric adjustable dump valve if you're interested.

    Could just be a bad map, who did it?

    I wouldnt fit an N75J unless the map is designed for it, although a new N75 might be useful if its overboosting just to rule it out.

    The J valve can cause boost spikes that cause limp mode. It is commom to map the car without the J valve and fit that afterwards to possibly increase the boost slightly. The boost comes in harder and spikes higher,but drops off quicker. I didint like the feel of it and went back to an F valve, suited the map better.

    Is your car DBW? or does she have a throttle cable?
