I have a 2018 Discovery 5 commercial. The middle section of the instrument cluster has disappeared, so now I can't see the fuel gauge or milage etc. After taking to a local 4x4 specialist they confirmed a new cluster is needed and I need to go to Land Rover for a new part. This with diagnostics is going to cost around 1500 quid, I can get a used cluster from Lithuania with the same part numbers etc, how do I get it coded to my vehicle as I think I need to?
