Mercedes-Benz E320 CDI Problem
While driving on I-95 on a sunny afternoon all of a sudden my dashboard warning signals started flashing one after another at lightening speed. The power was suddenly gone. Nothing from the gas pedal. Was able to coast onto emergency lane and awaited tow. Have subsequently been told (car still in shop) that my central gateway computer malfunctioned.
