I am glad this thread came up because last week the odometer/trip stopped working on my 300SEL last week. Since I have an erratic fuel gauge. I had been "resetting" the trip odometer like a fool to keep track of my mileage. I have owned three 80s Mercedes and never had a odometer problem, although I knew it was a common deal, so I never used my trip odometers on those cars. I am sure I sped up the failure on my 300SEL by resetting it when I refueled. Its over now and its broken.

Aside from the parts, about how much would an Mercedes shop (not dealer) charge to remove the cluster and replace the gears on a W126? I would think a good shop (we have a couple) would have a good source to buy these, or may have some extra parts onhand.

I guess I could call tomorrow and get a quote, but wondering what people here had paid on average... I am not much of a DIY'er, so not really wanting to do this myself. I also need to get my coolant changed out and a new EHA valve, so it may be a good time to do that as well.

Thanks.
