hi guys. i run a sprinter 311 long wheelbase and recently it cut out twice on the motorway. i pulled over onto the hard shoulder on both occasions turned off the ignition then back on and away i went. Yesterday morning however i went to start her but che wouldnt start from the key but would bump. I went for a drive for a while, put it back on the drive, turned ignition off then back on and same problem. Any ideas please or has anyone experienced the same problems. cheers.....
