Hi all, well I'm now experiencing the annoying 'drone' or 'mooing' sound on my TDI75. The noise is only there at low revs/on light throttle etc etc. Does anyone know how/where this can be fixed, at reasonable cost? I don't really want to take the car to an Audi Dealer, but the car is booked in at Audi PRESTON while I consider my options. Can the EGR valve be cleaned and/or related pipping tied up somehow, to reduce the noise/vibration? Apart from the noise, engine performance is excellent. Car has FASH, is still under Audi warranty (is this a warranty job?).
Thanks for your help
