My panel has a lot of failed leds. Showing 83,000.
Obtained a used and supposedly functional one with 53,000.
Took 'new' one and asked BMW to fit it and adjust the mileage to mine. They were willing but said the best they could do would result in my odometer showing 83K+53K = 136K!
Quarry BMW who sold me it said the mileage could be adjusted to match mine. BMW say it can't.
Assuming BMW matched the 'new' one to my car and I installed it. What would be the mileage result of putting the old one back if I decided to sell the car. Would the mileage I'd accumulated show correctly on the old one? BMW didn't know the answer to this.

If BMW can't do it, plenty of others can, there are even kits on ebay for £130
cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&category=...1
and plenty on there, so there must be a lot of these systems around.

Took a look and these things are not only pricey but probably wouldn't work on a modern computer - DOS!

I decided to ignore the reams of expert advice I've been getting on this. So I took out the 'old' one, swapped the ECU's and lo, correct mileage, correct everything - matched to the car. Obviously in this model the mileage info is kept in the ECU.
