My turbo is just about to let go...
Over the last few weeks the car has developed a whine/vibration once into boost. It was initially only sporadic at high boosts and high rpms, but over the course of the last month or two, the whine/vibration is such that now, in 6th, above 3000rpm and whenever out of vacuum, the whine/vibration manifests itself.
Oddly, it doesn't seem to manifest itself in the lower gears, but then we know the load on the unit is higer (= spin faster? That said I always thought there would be a unique relationship between boost and turbine speed such that I'd get the whine/vibration even in the lower gears?) when boosting from low down the rpm range in the higher gears.
Before the thing blows itself apart, are AET the best source for re-conditioned turbos?
They are quoting me £150-465 for a re-conditioned unit. They have a free inspect and diagnose service whereupon you can decide what you want done to the unit. 4-5 days between getting it off the car and having it back in your possession.
A new one ex-stock will set me back £650 from AET.
Vagparts are quoting £790.83 for a new unit.
All Audi are checking their inventory for a second hand one and have a couple: £175+VAT, guaranteed for 3 months FWIW.
Any suggestions on replacement units much appreciated?
Haven't checked Ebay....
Cheers.
