My car must be F****d then...............

on the road  

about the same as everyone else's ... although I noticed on the pre-facelift the idle didn't drop when air con compressor switched off, it does (or did) on both facelifts ...

Climate off: 450 - 500 RPM
Climate on: 600 - 650 RPM

This is with the engine at operating temperature.

However, if the engine is idling and I turn the steering wheel, the revs increase.  Is this an indication that the idle control valve is having trouble?  In the past, I thought that it was to do with the steering box detecting load and increasing the engine revs accordingly to provide extra effort.

There's a pressure switch in the PAS circuit that detects rising fluid pressure (= steering effort) and tells the ecu to give it a bit more beans to prevent a stall.

Thanks for this Kevin, it confirms what I thought.  Earlier in the thread there is a statement that says about the AIC valve.
