While I wait for the dealer to get back to me on the AC compressor, another problem has come up a few times.
While I was starting the engine there was a strange noise like metal rubbing on metal for a fraction of a second and the parking brake remained on.
This has happened about 1 start in 10. Turning off the ignition, locking the car and unlocking the car unlocks the parking brake.
Any ideas anyone?

 

See post #32 in this thread for what may be a similar mechanical fault:

The second link in that post sends you here, which has pretty pictures of the innards of the actuator:

You may find the rest of the first thread of interest, if you care to start from the beginning.

 

Not the same as anything here. I can't normally hear the park brake operation, I can feel it on the brake pedal.
Tomorrow I will take my i930 and see if it plays up again, Cooler weather forecast in the next few days so a look under the rear
end may be in order. will post what I find.
Btw did a silly thing today put some diesel cleaning stuff in the last 25 litres in the tank. Only cost 9E. Unbelievable after only
5 mins there was a big difference in smoothness overall and no hesitation between 1800-2200 rpm. I didn't believe this stuff worked
but the dealer was very insistent that I try it. Tomorrow I will do a few Ks and see if it is still the same either way.
