Re: Electrical, hydraulic, or tensioner problem? [re: Bastian Preindl]

I start disagreeing with myself but first: Do you know, that auxiliary drive belt for the V8 is available in three different dimensions? The possible lengths are 2433, 2460 and 2480 mm. I mention this, because I guess you've made a "few" modifications on your car and I'm searching for the relation between the fault an the weather conditions. Due to that, the moisture and an over long v-belt might cause your problem.
There is one simple way to check the tensioner: Just pull the belt on it's long side (at the bottom). You should feel significant resistance and see the tensioner lever moving without jamming.
Now to my doubts:
Bastian has mentioned the Servotronic steering rack- this was wise!
If the steering ECU has got no (or not enough) electrical power supply, the steering support will collapse. So the alternator might be the cause in deed, because you've written, that the voltage rate was decreasing steadily.
If the pilot lamp is flickering during acceleration that will be a sign for worn carbon brushes.

Beste Grüße
Tim
