Trip Odometer - PeachParts Mercedes-Benz Forum

Just got the Tiger Tank back from the shop a couple of weeks ago and it was time to fill her up. Filled up (@1.86 btw, $.03 cheaper than premium unleaded) and pushed the button to reset the trip odometer and - nothing- . The gauge didn't mover a smidge.

I just had the outside temp gauge replaced and the clock rebuilt. Is it possible that something was not aligned properly when my mechanic reassembled the dash? He said "no" but offered to take a look at it for me, the next time I have it in for service. Was wondering if there was anything I should try myself meanwhile ? (like look for an odometer activation switch on the dash - sorry inside joke

)

Now, you are sure you are pushing the correct button? I mean two weeks apart and maybe...

I'm not 100 percent sure about your model, but my 123 chassis has a metal fork-like arm that goes around the bottom of the reset knob and shaft in the insrument cluster. It protrudes out from the speedometer gauge assembly. It could be possible that it is not aligned properly to function.

TigerTank:

I beileve Old Deis is still poking about the Antenna incident! Call me if you want some moral support while pulling the Instrument Panel. The actuating mechanisim is fairly plain to see on the back, if yours is similar to mine.

I'll probably be pulling Clark's in the next couple of weeks to replace his clock capacitors if you want to wait that long. Note: Pulling the IP does require a very specialized tool, available at your local dry cleaners.

Here you go TigerTank. A graphical guide, just for you.

Pretty ballsy for me to crawl out from under my car so soon, right Old Deis?

Thanks to all. Very useful info. River, I'm going to get one of those fancy MB dash puller tools and pull her out this weekend. Now I'll just have to locate my sledgehammer...

Will let you know how it goes.

Thanks again!

I remember Frank King writing once that he had problems with his trip odometer because he reset it to 0 while the car was moving. He warned that you should reset it only when stopped. Think he was talking about his 123 diesel.

Calvin:

I believe this rule of thumb (pardon the pun) applies to all VDO odometers with the drum type mileage accumulators. I was discussing this with TigerTank last night. The gear train in the odometer is fairly flemsey (intentional).

Well, I didn't get the dash out this weekend after all - I was too busy pulling the battery for a charge and check. Die Hard International Series - seems the battery is OK. Ran through the threads here and it seems likely the voltage regulator is on the fritz. Ordered a new one (generic - Germany) $20 from Fastlane and will execute that routine this weekend. Trip odometer isn't going to make a difference is she won't start!

Wife is peaved b/c it died on her - told her she didn't know how to start a diesel and she broke it!
