Trip meter not working

1996 90 300Tdi. Speedo works fine, although the needle is a bit wobbly. Odometer records overall distance correctly. Trip meter goes up to about 1.3 miles after a reset, and then stays there. Is it worth getting inside and seeing if it can be fixed, or is it a case of a) another from a scrapper, or b) live with it?

Fuel gauge is unreliable (ran out with nearly half a tank showing on the gauge) so it's quite important to be able to track distances.

It's on 136,000, so hasn't done too badly.

When my trip started playing up the speed packed up all together shortly afterwards. I ended up buying a new one on ebay.

I had this problem after taking my speedo apart to sort out the melted bulb holder. If I remove the rubber cover over the reset knob, it works fine; if I replace it, it exhibits the very same issue you describe. Try removing the rubber cover and see what happens.

Thanks for the input. I was hoping it would be a common problem (on my last car, it happened all the time and it was just a matter of gluing a small wheel back on the speedo drive). Never mind - when I get a minute I will take the speedo out and have a look, and see if leaving the rubber cover off works. If not, it's back to eBay, where s/h clocks are bloody expensive!

Cheers.
