1990 300E ODO Problem
 

My daughters has well and trully "fixed" her odometer by (I think) resetting the trip meter while on the move.

Anyone fill me in on what I need to do to get this legal again ?

Also trying to ID the part number for the Amber bulb on her clear corner lights.

Thanks

I have done this myself on the same speedo/odo.

I don't recall the exact procedures, but it was a relatively easy, one-evening fix.

Pardon the vagueness and lack of details, but it's been a year or so.

I recall that the dash pod pulls out toward the steering wheel. I was able to disconnect all of the light plugs and the vacuum line by twisting the pod to odd angles. The speedo cable was a challenge. I recall going in just above the brake pedal and loosening the cable in there. THis gave just enough slack to pull the dash pod out a little more. The cable then unscrews.

R&R was logical, straightforward. Pay attention to the possibility of the thing falling apart.

My situation created a loss of friction between a pot-metal drive gear and its steel shaft.

Pulling the shaft out from the gear, I crimped it slightly with a vise grip to give it some texture. A gentle rap or two re-seated the shaft, and I've been back in business for a while...

The job was disconcertingly easy, as if a bad guy hooked up a Dremel to that shaft, he could have spun back 100K in several seconds without disassembly. Not good.

Good luck...

Resetting ODO on the move
 

I was not aware that the trip odometer could not be reset on the move. I have done it several times. Is this a no-no?

300E Trip Reset
 

This is what I have been told..

"if you keep hitting the trip reset while moving eventually the gear wheel will become damaged and it will stop funtioning"

This is what happened to my daughters, the odometer and the trip meter no longer function.

In the previous reply I think the assumption was that the cable had become disconnected, this is not the case or the speedo would not work (right ?).

Someone told me that I might have to get a speedo tech to rebuild it, sounds $$$ !. I thought if there was no other way I might as well get a working used unit and replace it, but then I do not know what the law is vis wrong mileage (USA).

I am used to being able to reset while moving, but on the 300E apparently you cannot.

Anyone else offer something in the way of confirmation of the facts or solution ?

muditt is right. You can't press on the go.

Repair is $$$, but see above. You can DIY.

You can also replace your ODO and change the wheels to the same mileage.

The law says you can't roll back and declare the car to be lower mileage...
