Audi A3 3.2 V6 DSG Running Issues***ADVICE PLEASE***
I have had a few running issues with my car its on 80,000 and is a 54 plate model.
Recently the revs when stationary were hunting causing the car to shake a little however once i revved the car it would stop.
The car went to Audi and they replaced the DSG ECU at a cost of over £2000 for free for me, the problem went away for a few weeks but then came back last week!!
I placed the car on ebay and someone agreed to buy it knowing the issues for £6500 which is massively reduced over the other cars around. Today I have gone to clean it and left it running for 5-10 mins and the problem was there immediately. I opened the bonnet and the engine was really shaking and the revs were hunting. Again, revved the car and it went away!
However decided to check the levels as usual and found under the oil cap a light brown residue with air bubbles in it, smelt the cap and it smells very similar to petrol!!
I have duly emailed the buyer to let him know as i can't justify selling it like that without him knowing.
I have taken a picture of the cap which I can email someone but has anyone got any clues as to what has gone wrong?
I know VAG cars have coilpacks which go and that can be the symptoms of the hunting revs but this oil cap issue is worrying and now when I really need to sell the car its concerning me ( financial reasons meaning it needs to go now whatever)
I can't afford to fix the car and plan to re-advertise on ebay for a reduced price in the hope someone is willing to buy a very very cheap car and fix it which their know how
