can anybody help me? My car is a a3 1.8t sport 1998 and the other day i pulled away from lights after at least half hour of driving, I put my foot down to leave some stupid corsa boy trying to race me. When i settled down into 4th gear i let the revs build and as the turbo started to spool there was a loud whining noise, the noise happens everytime the turbo spools up now and gets louder the more it boosts its defo lost pressure aswell. I can only explain the noise as sounding like a supercharger?? A friend told me its blown or split a hose but ive looked at all the pipes i can see under bonnet and under car, It only makes the noise under load thats whats making it so hard to find. A mechanic told me its a common fault with these engines but couldnt tell me where it was and was to busy to look his self! Anyone else had this problem please help
