    Default z20net power problem any help or ideas needed

    Hi guys

    i have a 2004 53 plate 2.0t now the problem it has is this every so often the engine light comes on and in first and second there is no power at all its only when i get into third ( just ) that the turbo kicks in more and it drives as normal until the next junction, now if i turn it off and on again it will be fine for a few mins or a few days but the light stays on all the time and out the blue the same lack of power again.

    i have had the fault read and it said the mass airflow sensor so i have had that changed and the problem is still there i have also been told its the egr valve but this engine does not have one according to the local stealers

    so if any one has had the same issue or just knows what it might be please let me know

    thanks

    it has been read by one guy who said no power going to it but that has been tested and there is also read by the rac and another garage but not the dealer, i have not tried driving with out it connected but i will go and try it now and see what happens as it was only today that the rac looked at it and cleared the code again so i will post the result in about half an hour

    What is the fault code ? Also pretty sure that most engines have EGR valves! ? And the symptoms suggest that as a possible cause.

    Ive just had my power loss problem sorted on my 2.0T. Turned out to be the accelerator pedal needed changing. The car wasn't regconising that the pedal was been pressed, therefore no power.

    My other car. 1972 1641cc slammed beetle. On the road finally!!

    hi guys firstly thanks for the quick response, i have just been out in it with the mas disconnected and there was no power at all so plugged it back in an it ran fine ( see how long it lasts ) i cannot remember the fault code exactly but it was something like p1019 or there abouts but it says it was the mas, i will investigate the other suggestions from you all over the next few days and keep you posted

    thanks again guys

    If it ran fine with it plugged in and badly with it unplugged it sounds like its working, or at least was when you tried it. Did the rac write the code down on a job sheet like the AA do?
    Now I need a turbo to keep up!

    The 2.0T seems to be the only one in the range that doesn't have one, so at least the dealers were right on that.
