    Hi, the EML came on about 3 weeks ago on my late 2000 1.8T, and the faults were:

    1. 16825 - Tank Venting Issue
    2.17544 - Fuel Trim System too lean

    Got them reset to see if they were a one off, and the light stayed off for 2 weeks and has now come back on, the above codes were back, as was:

    17705: Pressure drop between Turbo and Throttle Valve

    Just wondering if these were common and what people had done to rectify the problems.

    Any help would be greatly appreciated

    Vacuum leak by the sounds... prob the PCV pipe under the inlet manifold...

    Start checking all the pipes for splits...

    Cheers for the links S3feates, was trying to remember the link for ages.

    Tufty - do you think this could cause all 3, or just the top 2? The link says the third could be DV related, but it isn't fluttering, which i thought was the tell tale sign it was on it's way out. Correct me if i'm wrong though...

    I am pretty sure it will sort all the probs... the third issue can result from split pipes... the link assumes pipes are in a good state... sort the leak out first then see how you go...

    Thanks alot, will check a bit later on

    Does the PCV pipe part number differ for different engine codes, or is it a universal fit on all 1.8t's? Reason I ask is if i need a new one, I am unsure which engine code mine is
