Hi all, I have recently purchased an Audi A3 2.0 TDI (2006) for my wife and got a major service done at the Audi dealer. After the service they noticed that there was a Whining noise coming from turbo charger and said a possible new turbo may be required. They also stated that both the Intercooler o'ring seals were leaking. My question is would fixing the intercooler seals fix the problem with whining noise from the Turbo? Considering that a new turbo cost £1000+ I don't really want to pay that sort amount if i can avoid it considering that also found other issues with the car that I need to fix. Has anyone else had this issue? What other options do I have? I am new to Audi TDI's. Cheers.
