faulty trip meter

Apr 4th, 2003, 19:49

my odometer & trip meter have suddenly packed up. The speedo is fine so I've ruled out sender & harness faults. I've figured out how to remove the cluster, but it doesn't look like something that a DIYer can attempt to fix.
I'm sure a new instrument cluster will be hundreds of pounds from the dealer and the chance of finding one in a scrapper with only 78,000 miles on it are remote to say the least.
Has anyone else had this problem? Is there anywhere you can get them repaired?
any advice much appreciated
cheers

Try some oil and a nudge on the last digit on the odometre, the trip runs of the odometre so if the odometre stops, so does the trip. Mine stopped in the summer during a long drive, I oiled it and then used a screwdriver nudge it a bit, works fine over 20k km later. My only other suggestion is to get one of a scrapper and set the milage to the correct one. You can also buy a new speedometre from the dealer, should be around 70-80 quid.

Very often the fault you describe is caused by a little nylon gear inside the speedo head which splits and no longer grips the shaft. If you feel competent it is quite easy to refix the gear wheel so that it does not move relative to the shaft.

All the best, Peter

Thanks George & Peter, with your encouragement I've just taken the instrument cluster apart and had a fiddle. The plastic gears all seem fine and with the motor removed everything moves freely. After putting it all back together it still does not work, so it looks as if the little motor, or the electronics controlling it, are shot.
So a trip to the scrapper is in order (after a call to the dealer - for a little light entertainment I'm sure ;o).
I was surprised how easily (and quickly) the mileage digits moved, so simple to clock a car if you are of the scumbag variety...
cheers

Indeed, or to reset the milage in accordance with your own car when you replace the odometre...
