    Hi guys, I'm new to the forum:bye: so i thought id start with an easy one!

    I have a 2002 A4 1.8t (163) and yesterday i noticed the kick i normally feel at about 2.5k - 3k revs wasn't there. I have been out again today and its still the same.

    It runs fine and its still accelerates smoothly, just not as punchy as normal.

    I can still hear like a whistling sound which i always assumed was the turbo, that doesnt sound any different in my opinion.

    As you may have gathered from the highly technical description of the fault i am no mechanic:confused:

    Any ideas on the fault and ways to test/fix it??

    Thanks folks

    Hi mate and Welcome!!

    First thing Id do is look for any Leaks, Check you boost pipes, could easily worked its way loose somewhere or you have a split pipe somewhere,Its just finding it, I found mine just by luck.

    .....Then it could be the Diverter valve split/Broken...but

    Thats where id start first with the pipes etc!!
