    Help needed A4 2.0T engine very rough and no power

    My 2006 2.0 TFSI A4 has been a joy for the last 9 months, I went for a drive tomight and accelerated off of a roundabout, there was an immediate loss in power although the car still drives very slowly, the engine now sounds like a bag os spanners and very lumpy.

    It's quite lumpy on idle and sounds horrific when revving, a bit like a subaru boxer engine with a bad exhaust.

    I had it remapped last summer with no problems at all.

    I've no idea what might be the cause, I've defo not put diesel in it.

    Any help would be fantastic

    Coil pack gone. If you get the car scanned on VAGcom it will tell you which cylinder

    I really hope so, I've got images of a Turbo vein in the engine somewhere....eeek!

    I've had it recovered to a local garage who will plug it in to their diagnostics tomorrow morning, I tried Glasgow Audi but they refused to take it after 6pm and stated their bollards would be locked

    Thanks again Byzan, I've just had a call from the garage, the coil pack has gone on cylinder 4.

    Should have the new one delivered on Monday, not got a cost yet but still smiling as I thought it was going to be a humungus problem like a snapped timing belt or turbo blown or something.

    Make sure they use a genuine one, pattern ones are not as hardy, and only cost a few more quid. Sub 40 for the part anywho !!
