I went into my garage to turn over my car after being away for a week, let it run for about 1minute, and burning oil started pumping out from the grille and sides of the bonnet. After further inspection, it's coming from the top-end of the turbo. Does anyone know what this may be, or may involve/cost to sort out? The car was given a full long-life service and full check at an Audi dealer which flagged up no faults whatsoever, and the car has only been driven 1mile since then (home and into the garage). Could it be the oil feed pipe? Any advice from anyone with experience of this would be really appreciated.
