I can see the weights and the springs in the base of the distributor and I'm sure it is contributing to the total advance. I was surprised to see a mechanical advance mechanism when I was under the impression the Motronic handled the timing duties. It leaves me a bit concerned about how much advance I might have at 5000 rpm and .5bar boost. I can't get back there with the light and measure that.
The distributor has nothing to do with triggering the Motronic ECU, that's done by the flywheel.
Maybe your car has a different distributor in it than it came with. Either way it has no effect on your year of Motronic fuel injection and ignition timing, it is only directing the high energy voltage pulses from the ignition coil to different spark plugs while rotating.
