I had this one once after a service. The dealer had looped out the idle
stabiliser (Audispeak: DIS unit) to make some tests, and had forgotten to put
it back into circuit.
On my 80CD, it's under the bonnet but on the other sied of the firewall from
the engine. It's a square box about 3" square (from memory - it's raining)
with two pretty robust 3/4" diameter connectors. It's taken out of circuit by
the simple expedient of pulling the connectors out and plugging them into each
other. So check to see if you have a lonely plastic box with two empty
receptacles, with two likely-looking connectors mated a few inches away.
Your symptoms are indeed those of a dead or AWOL "Digital Idle Stabiliser".
