My 2009 RS6 Saloon has started suffering from very small oil leakage. It is a well documented serial problem of the model and while the defective part is simple, accessing it requires engine removal. 

The car is a keeper and has higher value for me than the current market suggests. If it was any of my other cars I would immediately fix it and put it for sale but there are fewer than 2000 of them built, it looks as new both inside and out and has 56 000 km...Plus I don't think that the world will ever again see another V10 TT engine :)

So I am looking for the best possible Audi service center in Germany specializing in Quattro GMBH cars that could do the procedure perfectly. Could anyone help me with recommendations?
