    Was it a main dealer who told you needs a set of turbos and ecu?
    Sounds strange..how long have you had the fault for?

    THere are fuel issues at the moment SE and killing Lambda probes..so back track when you last filled her up and what fuel and station you used

    It could also be something as simple as the MAF sensors.

    Unplug them both and see what happens..you can get to the plugs down the back..or get an Audi bod to do it.

    How old is your car..you got warranty??

    well at first i thought it might b something to do with the fueling it was booked into amd for the ecu upgrade and exhaust etc so went ahead with that hoping it might fix it or they would spot it but it got worse as times gone by

    sometimes it goes like a 500hp car then the next minute it drives like a 50hp car it sometimes accelarates strong then goes completly flat

    I'll take a pic of the plugs.
    Sounds like MAF to me
    Get some fault codes if you can..from the Audi dealer who looked at it

    dude im in surrey and I have to say the place I will be taking mine back to is the Audi main dealer in walton-on-Thames they look after you very well and stuff as I told Marmite when they dropped it back, they just did my suspension an stuff, Neil the Service Manager was great.
     
  18. MRC is the place to go.. without a doubt....

    Sounds exactly like what mine did, they should be able to diagnose it if they have any idea what they are doing, sounds like 2 turbo's to me, its probably your wastegate diaphragm thats gone, to replace that they replace the whole turbo, and when they replace one turbo you have to replace both or they will be out of balance.

    £4000-5000 it cost the warranty to do mine.

    Take it to a proper Audi garage that knows what they are doing though and get it diagnosed PROPERLY first.
