Hi All, I own a Audi A3 sportsback 2005 TDI 140 bhp with 50,000 miles on the clock and have found droplets of oil on my runway . I have had the car on the ramps and removed the bottom cover and it seem to be coming out of the hose going into the cooler. I removed the pipe and have a small amout of oil from the pipe. I also removed hose from the other side of the cooler and notice a small drop of oil as well . I have run the car for 2weeks and the oil leak from the outlet pipe has started to weep oil again ! I wonder if anyone has the same problem ? Can the cooler be cleaned out in situ or must it be taken out to clean it and if so what with ie cleaning fluid. Many thanks John.
