Problems with A4 T Sport Quattro

    Audi A4 1.8T Quattro Sport (99V) - Remapped to 225BHP

    In April 2003 I had an engine remap, new Miltek exhaust and upgraded diverter value all done by AMD. I noticed straight away that the noise from the turbo had changed (I assumed this was the change in diverter valve). Ever since then the turbo noise seems to be getting less and less. Power does not appear to be affected but should I be worried about the decreasing noise level from turbo???

    I have also noticed recently that when the car has been driven in the rain it makes a funny kinda gurgling sound from underneath (somewhere near the front). I am guessing it is the exhaust????? Should I contat AMD and get them to check it out or am I worrying about nothing?

    Thanks in advance for any help.

    I have an A4 1.8TQS with a remap, dv and Miltek - the turbo noise on mine did not change with the remap or dv but is louder since the Miltek went on.
