HI guys I'm new to this thread.... I've got a 2008 audi a4 2.0 tdi manual.... three weeks ago are oil pressure light come on as my partner was driving off the drive she went about 100 yards and drove back to the house and told me of this light, so i got the car picked up and taken to a local independent garage they new of this common hexi drive failure where the part on the engine side rounds off, so it was going to need the new upgrade kit, so i thought thats fine we need the car get it repaired, being the car is only done 63,000 miles with full service history with audi up to 2012, and the rest by an audi specialist before i got this car, it had only done 57,900 miles 14 months ago, so its not doing a lot of miles, but when the garage said we can repair it we said ok then they said you might swell fit a clutch as its low, so being i like my car to be good, but when we got the car back on this saturday morning, the garage said the new parts need to be bed in as the car has now developed a whining sound and I'm not happy with this sound but the garage area fobbing me off..... is this sound the turbo?? as it makes this sound in or out of gear, and when i go slow its not noisy, but when we go along and but more revs to go faster the whirring sound gets loud... and if I'm going alone g fast and dip the clutch it stops until i get revs back up to speed. so not happy with audi. can it b e the turbo for sure ?? because the garage need to sort this problem out. its not fair on us if it was not making this sound before thanks for reading my story..... please to give me your feedback. many thanks.
