2004 Audi a4 avant 1.9tdi 130 1. When steering is on full lock I get a squealing noise from the engine bay similar to this Mazda 3 2008 weird sound at steering full lock - YouTube this only happens when engine is ticking over, when rpm is increase the squealing disappears. The tensioner has been replaced around 5k miles ago 2. The dash beep no longer works - everything else seems to be working perfectly. Very annoying as I keep on leaving the lights on!! 3. I recently had the clutch replaced but ever since I have had a strange humming/vibration only when the car is engine braking down a steep hill or at high revs coming down through the gears. I spoke to my mechanic about this and he said that it isn't something I should worry about - so just trying to get some backup before I go back to him. any help or advice would be much appreciated.
