Odometer Running Fast??

[ebod]

I replaced the odometer gears on my 89 325i Convertible. The gears just stopped working and I didn't drive it more than a mile or two since the odometer stopped working (it stopped when I re-set the trip odo at the gas station). My car has the VDO gauges. I replaced the gears. Per the Bav Auto writeup, I used the E3 gear with the same number of teeth as the old one (the E1 and E2 gears are apparently all the same). When I put the cluster back in and took it for a spin, I immediately noticed that the odometer was accumulating miles way too fast (almost at 2x what is accurate). Any thoughts about what may be causing this (I'm sure it was some sort of DIYer error)? Could I have switched it somehow to KM from Mi? Any suggestions greatly appreciated.

Thats weird. Sounds like an incorrect gear was used

So your new gears matched up exactly to the old in size and tooth count? I don't think there is any way to switch between miles and Kilos as there is a mile kit and a kilo kit. You didn't get the kilo kit by mistake? If everything is the same then welcome to the mysterious world of BMW odometers. I think this design is their first move to electronic and combines the worst of mechanical and electronic with 5000 gremlins embedded in it. Mine is finally working correctly after I had my cluster rebuilt but I am not ever going to use my reset button.

I think I found the problem and, I'm embarrassed to say that it's me. I did the same short lap in my e30 and my son's car and they came up about the same. It was only a 1.8 mile lap and, because my son's car has a digital odometer it was impossible to say they matched perfectly. It's certainly not off by a factor of two though.

Have you maybe switched to a different size rear tire at the same time? That would explain a difference as well.
