That will be the oil seal gone, don't drive it and get it to a turbo specialist, but might cost more than the car is worth, but a diagnosis should not cost too much. all depends on the condition of the car really. if all else is ok and the car is ok, but be aware that it has the potential to cost a lot, go to the vw audi forums and google turbo oil seal problem a4 tdi, i just did! Good luck!

All turbo's pass a bit of oil past the seals. Are you having to top the oil up frequently & seeing blue/white smoke out of the exhaust. If not, it may well last for many thousands of miles.

Where is the oil coming from. There are two oil pipes connected to the turbo. If the leak is internal and the bearing are worn then the oil will leak into the pressure pipe going across to the intercooler. This can also be caused by a blocked engine breather preventing the scavenge return feed form the turbo from working properly. Find an Audi/Vag specialist or a turbo specials and get it looked at.
