2007 CLK automatic

[torie71]

Was driving the clk yesterday I went to accelerate and there was no kick down , it was slow and would not pick up speed . There was no warning lights on, I arrived at my destination and left it a while and it was fine no issue on way home and still ok !! Should I be worried ?
Thanks vicky

I had something similar when I first bought my C270 S203, except the lack of kickdown (plus unable to rev above 3K RPM) did not go away. Turned out a replacement MAF was required, don't know what it cost as car came with a warranty, but can't have benn too bad, garage only had the car for an hour or so.

Sounds like the car was in limp mode , sometimes the engine management dash light won’t come on until it’s detected the fault a few times .
The car will still probably have logged a fault code .
As it’s happened it will probably occur more regularly now before permanently going into limp mode . Best make mental plans to visit an MB specialist

Lots of sensors that could cause that. Mine did it and needed a new NOX sensor. Best get it hooked up to STAR at a local indy.

Good luck

Dreaded electroplate? Gives similar problems with no warning lights.
