Hi All,
My Audi A3 TDi 2.0 has started using water. I'm regularly topping up the resevoir around once a month. No obvious leaks, rad seems fine and can't see any split or leaking hoses. I popped her up on ramps today and removed the sump guard for a looksee. Again, no obvious signs of leaks ... no drip marks or coolant stains that I could see. I fired up the engine and went back below, and whilst looking up the back of the engine I noticed bubbles coming out of the side of the turbo!! There appears to be a leak at the side of the housing where there is a round plate secured by bolts and the leak is around the edge of the plate.
Some history .... when I bought the car the turbo blew on the way home!! I had to have the car RAC'd to the local dealer and was over a grand for the repair. Not a good start, but since then the car has been great. Can anyone tell me what the leak is likely to be. I presume the turbo is water cooled and that there is a seal gone somewheres. I'm just worried that this is what caused the original turbo to go, and that the dealer replaced the turbo but did not notice the water leak?
There is no sign of contamination either in the oil or the coolant.
Any help would be welcome ....
Cheers,
Ripface.
