Anybody here who knows whether my -98 A6 Avant/Quattro 2.8 has a cam belt or
chain driven cam shaft?

Might be wrong but I never heard about chain driven cams at Audi / VW

The 2.0 litre 16 valve engine in my 1994 Audi Coupe had one cam driven by a
front belt and the other by a rear chain. The chain wore slack on those
engines and idling they sounded like an old sewing machine.

Timing belt. Should be replaced around 75K miles

They're starting to go back to chains now. I believe all the Audi V6 and V8
are now chain and some of the 4 cylinders too e.g. 1.8TFSI and 2.0TFSI IIRC.

FYI, the VR5, VR6, W8, W12 and W16 are all chain driven.

I believe most manufacturers went to belts in order to have quieter engines
but obviously they add a big cost to maintenance every few years and are
less reliable.
