Hello folks, long time no see. Well unfortunately the Quattro is yet again the bane of my life and I need to get it sorted or get rid of it. So I'll go through the scenario/timeline as best I recall and then get on to the current problem. Car 1998 Quattro 2.8l 30v V6 Avant It has a burning oil smell occasionally after a run. Gave it a service. No problems as such from that lol Had a fuel leak from the filter so changed that out. I still have a leak but could either be cracked tank or more likely a **** crush washer on the filter. Not had chance to swap a new one in yet as the current problem appeared. Cleaned out the breather pipes as they were gunked up as I expected. Occasionally it would have a small misfire but nothing regular or really problematic. After filter change it started as normal but due to leak never took it off driveway. So after sitting a few days it would to start albeit a bit rough and would clear a little if revved. Then became harder to start and is obviously not firing on all cylinders at any time. All plugs were a little sooty so cleaned them and swapped them around but no real difference. I have checked it with a cheap scanner and nothing, checked with my Vag-Com and that reports no codes. so I'm after any ideas as to common faults that may cause this or something I've simply missed. I am at the point where I will not throw money at it as it's had enough already, so I need to track the problem first. My current thinking is to just sell it, probably as parts. Seems I spent more on the exhaust than the thing is worth. any wise words appreaciated, cheers.
