ML320SE cdi:Revs too high.

[neethlingj]

Hallo All,
This is my first post ever and my English is not too good-Please forgive.

Had problems [jerking and lack of power] with my transmission for 6 months and the car has been to the dealers 6 times already.

Bought the car from new [07] model and problems started after the first service.

The second last visit a new valve body was placed but still did not solve the jerky transmission. With the last visit all sensor readings was send to Germany and new software installed and re-adaptation done. This solved the jerky transmission problem.

Now it feels like the revs are too high. Before at 80mph the revs was at 2000 and now it is at 2500.With acceleration the revs are much higher than it used to be. Is this normal and should I do something about it?

Please Help....I need peace of mind

Hello and welcome,, they have done something wrong and the autobox is not going into top gear, that is the only way that the revs can be too high.

The car will have to go back,, did you buy it from MB in Poole by the airport

sounds to me like they have set the fill time adaptations for the down shift but not the up shift, yes new software does sort out most of the faults but not all, had the same with my r,class, after driving and setting it up with another tech and star machine it was fine, as malcolm said take it back and tell them you dont want it back till its right!!
