    Can anyone advise me or have had this same problem?

    exhaust sounds like its blowing/bit louder but took it to 2 garages including audi specialist who couldnt find anything wrong with exhaust.
    called audi but they said 85 p/h to look at and i thought........

    Turbo kicks in a few hundred later as well.
    the exhaust sounds worse at cold and on idle it dips up and down a little.

    theres definately something wrong but i dont know.

    the exhaust will sound worse from cold , as they have a secondary water pump , sounds like the exhaust is blowing , for a minute or so , and then cuts out , the idle could be down to a idle valve or something sticking

    thanks guys for the advice.
    will look into the maf as i think thats pretty cheap to replace.
    trying to do everything i can first before having to take to audi.
