Hi, A few days ago the yellow coloured "Engine" light came on with no text messages on the display. At that time did not affect the performance. For the following couple of days that light was off and the car was OK. Today the light was on again, the car was fine for about 30 minutes and then entered the limp mode. I tried switching ignition off and on many times, I even disconnected the battery for about 30 minutes hoping to reset electronics in this way but it is now permanently in the limp mode. When I start the car the "Engine" light stays on. During the first few seconds after starting if I rev the engine it does go to 5-6k. However within seconds it drops to 3K. If I wait a few seconds before revving the engine then it does not go beyond 3K even for a few seconds. I had a limp mode problem more then a year ago but the symptoms were completely different and it cured itself. The car was serviced with MB specialist about half a year ago and no problems reported - so it would appear to me this is a new problem and the old one resolved itself. The previous problem was discussed here: http://www.mbclub.co.uk/forums/engi...ft-s211-e320cdi-enters-limp-mode-judders.html Any advice on the problem and how to fix it would be greatly appreciated!
