Don't work..Any suggestions on how I can get my tach and speedo to work?

My only suggestion would be to disconnect then reconnect the batteries again. It might just reboot things. Important! Do it this way though due to the pyrotechnic charge on the starter battery!

The procedure is to wait at least 60 seconds after the ignition is turned off. Then remove the starter battery earth first. You can then remove the main battery connections, although you will really only need to remove the earth. Leave it a few minutes before reconnecting the main battery, followed by the starter battery.

Hope that helps.

Reboot the car. If it doesn't work get a VAG-CAN tool and run the tests on Address 17
