I have a '98 A6 1.8T Auto (UK) and it has recently been stalling when
idling. It's tick-over speed is about 5-600 rpm but it sometimes dips below
this and then stalls.
What should the engine speed be on idle?
The other worrying factor is that when the engine cuts out, the steering
locks. Is this right because if it is what would happen if the engine cut
out at high speed?
According to my information, the engine speed at idle should be between
760 and 960 rpm, so I guess that you should expect 860rpm as a norm.
I suspect that what you are noticing is the lack of power assistance
when the engine stops. The steering is not 'locked', it just becomes
extremely heavy. You shouldn't really be attempting to turn the
steering whilst the car is stationary - that puts a tremendous load on
all the steering components. When the car is moving, it should be
possible to steer without power assistance, though you may require
muscles like Popeye!
