Hi Alan, 'fraid I have no experience of Audi 80's, but I had a similar prob on my B6 A4; the cabin filled with a petrol smell. Like you, no appearent leaks, drive-way remaimed dry etc. Called out Audi Assist who immediately pinpointed it as a tiny crack in the fuel filter - enough to let the smell out but not enough to result in a drip. Replaced in about 20 mins. On the A4 the filter is located on the underside beneath the drivers side passenger door. No idea where it is located on the 80 but it could be a contender for your problem.

I had this in my coupe 20v, problem turned out to be; the carbon cannister unable to empty itself of petrol fumes, because there was a big split in the engine breather hose. Changed the hose, no more smell.
