Hey guys, First post from a new member so please be gentle!?!?! Just got myself a 99' T A3 1.8T with 97k and FSH, My question is should you be able to hear the turbo whistling? The whistle starts at about 2500rpm and is only heard with the window down. Is this normal? I previously had an A3 TDI and the whistle was louder on that. Would it suggest a leak maybe? If so which hoses do I need to check? I have Vag-com which brings up no faults, is there any way of using Vag-Com to check for leaks? Any help would be gratefully accepted, even if its to reassure me its normal. Also I got rid of an Alfa 147 2.0 for the A3, the Alfa also had 150bhp but felt quicker, should the A3 have a big surge when the turbo kicks in? Thanks, Graham.
