Hi, Any help or advice would be greatly appreciated. I have got a Audi A3 2.0TDI Sport, 115k on the clock. All has been fine untill a few weeks ago, I had a coolant leak which was repaired, when I got the car back I took it out for a 'blast', I got to about 65MPH and the car lost all power! I could carry on at about 50MPH, but it had no 'pull' at all, pulled over and started back up, the car was back to normal again??? This has not happened since, after looking on forums I believe this could of been that the car went into 'limp mode'. Since then (I don't think it was there before) I have noticed a whirring noise like a distant siren when i rev the car, not really loud but loud enough to notice it, I also noticed I am losing some oil, I have looked under the engine + it looks as though the oil may be coming from the turbo area. Has any one come accross these issues or know how to correct this problems - is my turbo on its way out or gone already? If so is having the turbo reconditioned ok or not recommended? Would be cheaper than having a brand new one fitted. Also any one with the same vehicle, what MPG do you get? mine is lower than I thought it would be - seem to average about 40MPG and thats driving steady. Thanks in advance, JIO22.
