I have a 3 yr old automatic C 180 Estate. I have just noticed that when I reverse the car it will slip forward if I do not hold down the break or push down on the accelorator. Does anyone know what the problem might be? It has not happended before.
Any help would be appreciated.

Do you mean on a hill?

 

[pauluden]

Yes I did. We have to reverse onto our drive - it is not steep but it is an incline.

Is the engine tickover rpm lower than it used to be?

As jamesmc if the idle is to low it will roll back, normal idle is around 750rpm
