My Audi 80 2.6E has had a small oil loss for almost half a year. This is expressed in such a way that the oil runs at some point on the hot exhaust and then produces burnt smell there. Unfortunately, you only see the oil when you remove the lower lining. Now I have had the car so often in the workshop. I had the cylinder head seals replaced, cost a lot of money. Now I am in the workshop every few weeks, they wash the oil down to see where It’s coming from here, but the source is undetectable. I’ve been driving almost most of the miles in the last few months with workshop commuters! Does anyone still know typical leak spots at the ABC machine? The workshop can’t find out where it’s coming from. I’m already close to leaving the car, although I just put so much money in it recently.
