Hi
I have a 2004 E class 200, 1.8 petrol.
I have been getting an error code that states my spedo is not working, but its working fine.
When i take it to the garage they reset it but it keeps returning.

I know the speedo reading comes from one of the front wheels and i do have a noisy bearing but it is not that bad as they can't tell which wheel it is when its on the ramp.
Could this be part of the problem.

Also the weather here has been very wet and a few times the traction control has kicked in, again could this cause the prob.

Cheers to all
