The turbo cars (especially the ur-quattro) are sometimes afflicted by noisy air
seals. What sounds like a belt squeal is in fact air being drawn in to the
engine past a leaky crankshaft oil seal.
The same problem is theoretically possibly on non-turbos, though I've never
encountered it. The test is to pull the dipstick with the engine squealing,
and see if the noise changes.
