So a while ago I did something stupid.... I added the dual gauge cluster to my 06 JCW. Thought it looked better, still do, but of course it didn’t work right. After some additional research there were different revisions of that cluster, I managed to find one that was more appropriate and it works well now. But in trying to get the first one I bought working a shop tried some coding options and broke my temp guage, it goes to the highest setting but doesn’t trigger the warning light. For some reason that shop didn’t know how to revert that change. Does anyone know if undoing it is possible or where I might go to get it done?
