I know little about 3.2s/DME. I have an SC. But while we wait for someone who knows something.......
Is the vane the throttle plate? That is opened mechanically by your foot, right? On the SC, there is an air sensor before the throttle plate that determines how much air is coming in. As it is moved by the incoming air created by the starter engagement it pisses fuel into the cylinders and all of the cold-start throttle by-pass air valves allow air to get into the combustion chamber to start. There is no throttle plate movement on start up.
On your car, the flapper thingie (air flow sensor barn door) moves to tell the ECU that it is time to squirt fuel. Not the throttle plate opening.
Folks talk a lot about the DME relay causing problems.
Try going into "Search" then "Advanced Search" and enter "DME Relay" or "Carrera will turn but not start" and do some reading.
FIY and with no value at all - The early Motronic systems as in your car sprayed fuel one bank at a time. The three left cylinders / three right cylinders. They had an on/off spray function the SC did not have. That is why the Continuous Injection System has it's name. It sprays all the time.
I spent many nights in the Herrington Inn in Geneva. Nice place.
All the best.
