The symptoms :

Suspension at its lowest ride height
Yellow light on dash flashes for a minute or so, then go's solid. Once that happens I can't disengage the ESP.
Bottom green light on ride height indicator constantly flashes

And I dont know if this is just a coincidence, but just below the fuel flap and to the rear of the offside rear arch (but not on the flared moulding) there is an oily residue.

What I'd like to know is the cure.


Cheers in advance.
