Thanks for the info guys... but it seems to have fixed itself!!!!! If it happens again I'll definitely take it back to the dealers.
Thanks again.
Richard.
take it to the dealers anyway. I think it will have thrown up a fault code.
I had the ignition switch contacts replaced on mine yesterday, (57 Ed30) it was randomly activating the Central Locking whilst driving, and usually would not unlock the car when the key was removed from the barrel. All sorted now.
The service manager did say that he had seen this before, and in the extreme would randonly switch the engine off, not a good scenario.
