Hello,

It sounds like the symptoms of a crankshaft position sensor starting to break down! May be worth getting fault memory read to check for any stored codes!!

Hope this is of some help!!

Have you tried not letting the wife in?

A mate of mine had a wet carpet on the drivers side of his ML. It turned out to be a very small pipe in behind the pedals somewhere which had a loose connection. It was a horrible job to fix he said.

Has the windscreen been replaced recently?.....if the scuttle/drain at the base of the screen isnt fitted properly it will allow rain to enter the car.
