No, it has neither.  O2 sensors weren't generally fitted to Audi
injection engines in the UK at that time - the legal requirement didn't
exist until 1991.  The idle stabilisation function is performed by an
'auxiliary air valve', part 049 133 453E.  It's mounted on the offside
of the inlet manifold, towards the front of the car.

Be careful when calling it a '1.8S'.  There was an earlier car with
this designation.  I think Audi referred to your car as a '1.8 Sport'.

Side of the block, just below the head gasket.
