Hi Jeanmarie and Jeremy
The Fuel Pressure Regulator IS a good guess, BUT it is not necessary to change this part in case of suspicion - it can be tested using a fuel pressure gauge.
For a couple of weeks the local Audi dealer had the pleasure of looking at my car, but without any result. So now I took it home again and await their test report. One of the things I asked them to test was the fuel pressure.
So far I only know that it - as I expected - was perfectly normal.
And no - I didn’t try to start an engine full of fuel. I can start and it is running at idle speed, but when I touch the speeder it drowns on the spot.
The flywheel teeth and the flywheel OT signal pin are tested. Both the OT sensor and the RPM sensor are also tested.
Thanks for your replies. You can still turn out to be right, if the fuel pressure turns out to be to heigh, but I very much doubt this is the case.
Regards
Lasse
