200 C230, can I replace the cluster?

[N41EF]

Okay, it's a C230 that I'm looking at, and the milage doesn't jive. It's a repo, so it has a checkered past. I've been under it and through it, the only thing that has me worried it that when the car lot bought it at the repo auction, the cluster didn't light up, so they took it somewhere to get it fixed. The car is suppossed to have a black faced gage cluster, and it has a white faced cluster. All of the warning lights appear to work, but the low oil warning light comes on at -2.0 even though it's on the dipstick, and the gear indicator doesn't show up If I bought a black faced cluster on eBay, disconnected the battery, swapped the clusters, and connected battery, am I in buisiness? or does this require a trip to the dealer? Is the milage stored in the cluster or in the ECU? can the dealer make them match?Will the cluster learn the milage from the ecu automaticaly? Will the Falcons be worth a crap this year?

Thanks, Chuck, moving hear from the diesel forum.....
