, I agree on the PAS, when the car is parked at idle....
However, as my experience may demonstrate, the PAS is actually surprisingly 'active' when the engine is running - and perhaps the engine being off (whilst track adjustments are carried out) will show up as 'wonky steering wheel' alignment afterwrds - on a test drive!
I often have to 'reverse park' in between cars in my street.. the result is that the last 2foot of forward travel is with a tight lock (to align the car with the kerb).
Although I finish with the wheels turned back straight there must be some 'twist'
, in the tyres contact with the road, BECAUSE I feel nothing through the PAS when I get ready to stop the engine but
as soon as it stops, the Steering Wheel will kick about an inch at the rim.... the PAS is happily holding the steering under tension.
Best to get all adjustment with the PAS active, I think
