Would anyone happen to have the pinout for the VDO-manufactured ISV
control unit with VAG # 443 907 393 L? It was used in quite a few 5-cyl
naturally aspirated models in the eighties. Mounts on three standard
relay bases in the inside relay carrier.
My Cq started controlling its idle rather erratically (valve fully open
most of the time). Since there's no on-board diagnostics in the car, I
need to check all the sensors, switches *and* wiring manually, but this
is a bit difficult without knowledge of the control unit pinout.
