I am unsure of your question. Do you have a problem with the instrument cluster? Is the speedometer not working? If the speedo is the issue then you may have a problem with the driver chip in the speedo. Replacement or repair is a possibility. Please repost if more assistance is needed. Dr. Hagerty

Thanks for your response. It certainly seems like the speedo driver chip from here, I recommend removing the instrument cluster and inspecting the unit after disassembly. It is likely that the driver in the speedo has failed, I also request inspection of the service interval board(the one with the batteries attached) As stated earlier, replacement of the cluster might be an easier way to address this issue, if so, a salvage yard might be a suggestion that would help. Call Autobahn dismantling @ (619)444-2290 and speak to either John or Sean. Tell them I sent you.
