My 1.8T A6 has an oil leak that resulted in me having to stop and put oil in the other day when the pressure light came on - I admit I hadn't been too on top of checking the level.

Pulled the undertray off to find the source of the leak and there is a pool of fresh oil on the passenger side, under what I think is the intercooler. Most of the hoses are coated with oil and it's not immediately clear where the leak is coming from.

The sump gasket looks a bit weepy but not to this extent (just typically for a 14 year old high mileage VAG car) - so where else is it likely to be coming from?
