Hi All, i'm new on here and have owned 2003 xs auto crdi for several months. It has been raining really hard for the last week or so and my car has no response form the gas pedal and is idling at 1200rpm. Once warmed up it the revs up on it's own intermitantly still with no response from th gas pedal. the engine management light is on and the OD light is flashing also. has anyone experienced this or has any idea's where to start getting this fault rectified? Any advice will be welcomed. Many thanks, John.
