Looked at an A3 tonight, '54 2.0 Tdi. 85k on the clock
Light smoke, more like steam coming from the filler cap when running, also I can hear the turbo whistle when it's revved. Not loud but obvious.
Any cause for concern? It has a full Audi service history. It went really well and didn't see any exhaust smoke when it was being floored.
What I didn't like was the trader told us someone almost bought it yesterday but his card hadn't been activated and then someone is coming tomorrow to look at it. They sound like selling techniques and I don't like being pressured into buying second hand cars.
