slight wobble on the rev counter when driving

[roobler]

Hi,

I have a 63 plate C250 and I have noticed whilst driving I have a slight wobble on the rev counter. It's only very slight but I was wondering if it's something I should look into?

Does the engine "Wobble" at the same time as the rev counter?? Any difference on performance at that time..

Our 2011 C180 also does this even at idle. I would say there is absolutely no change to the revs. It's like the cable being slightly loose on an old school odometer. Something I have learned to ignore for the last 3 years!

It just seems to be the rev counter only, there is no change in the engine. I'm taking it in the a service soon so I will see what they say.

Had the same issue on idle, took it to The dealers as I had been told there was a service bulletin issued relating to a fix for this fault.
