    Hello,

    I have been having problems with car shuddering when the car is cold and also with picking up speed going uphill on the motorways. my car is a 1.9 tdi, 110.

    Today, I cleaned the Egr Valve and manifold, this has made a difference, but will see in the next few days.

    I then looked to see if there were any fault codes and the following were shown...

    p1156
    p1256
    p1163 intermittent
    p1550 intermittent
    p1161


    Can you please help with the breakdown of what these code mean.

    Many thanks.

    Niaz.
