odometer stopped at 300k

[myles]

I've successfully swapped my car's instruments and coding plug with a 1990 535im. The main trick is to make sure that the donor car is from the same market (US, ECE etc), has the same engine, transmission and fuel tank.

The early cars do have a coding plug, its just that it is very different to the later ones. The early one is a black thing that is embedded in the brown connector in the wiring harness for the cluster.

What about using a "mileage correction specialist" (as they advertise in the UK) to reset the speedo to 0000000 ?

Just a thought.

It's probably the last resort. I want to exhaust all other options first.

I'm still working on this problem.

Shazbat!
I have an old cluster w/o the coding plug (grey back I think) somewhere for any one who wants to experiment.

All grey cluster are without a coding plug. On the grey cluster the coding plug is located in the wire loom to the cluster.

In Germany on the E34 forum there are some guys which reprogram a cluster with blue or white backplate and the chip installed in the back from the data of the donor car to the correct data of the car where the cluster will be installed then. Even the mileage will be set to the correct mileage of the 'new' car.
But what they do not do is to program a mileage upon request. So one has to send in to them the old chip and the new chip which has to be reprogrammed. If they can do, you can do probably too.

How do I contact them?

Maybe someone in the U.S. can help you, try this forum, these guys are specialized on electronics for BMW

I'm still working on this problem.

i want to try this on the white-backed cluster i have (need to add about 100km), but you could try resetting to zero on yours... i've got a couple years to go tho before i need to worry...

from the site i linked previously...
"Reset the plug yourself: I haven't checked it yet, but I was told by someone you can clock in a speed signal of 100 kHz. This equals a very high speed (about 60 000 km/h). The plug should then store the mileage in it's RAM. As it can't write settings over 300K in into the ROM area 300K you will have to wait until it's been around 1 000 000 km. It should then write 000 000 back into the odometer. This costs about 0 Euro. Highly recommended. If you have tried this and it works I LOVE to hear from you!!! "

not sure what kind of a device you would need to do this but it's guaranteed to be way cool!

Ahhh... so stay away from earlier cars advertising "only" 300k

[ahlem]

So what does it mean if my '90 just hit 310,000 miles? Do I have later guages?
