I have some line on the digital display that are not working. Is there a way I can repair this myself? Any suggestions on where to buy spare parts?

Looks like I may just buy a used one. Is there a need to have the dealership reprogram it?

Yes, if you want to have the actual mileage transferred to the new cluster and certified.

That will set you back by $235.-

what if I do not want it certified, are there any other options?

The odometer reading of a US inst cluster can not be changed with MB service techniques once a certain low mileage has been reached (like 150 or so). You will have to hack it. The variant coding that will be required to get various systems to operate will be resetable if not already correct.

Thanks! My car has 145kmi, the used cluster 120kmi. I suppose I can just disclose the difference when I eventually sell it.
The used one I am getting is also from a 97 E420 so I cannot imagine there should be any functional difference.
