I'd suspect the AC controller head or one of the vacuum lines. Back in my
Dealership days, it was a common occurance on older(pre '88? cars) and Audi
issued a TSB for installation of a filter trap of sorts. At that time it
was discovered that the units would fail because oil was being drawn into
the units through vacuum.
