Oil Temp Gauge issue

Wiesbaden

Thanks, will try that. Dealership also said maybe to disconnect the battery and touch neg and positive ends together to discharge the system- capacitive discharge , then hook up the battery and see if that helps. Not to sure, but that's something they can do because I don't feel like really messing up the electrical system. Or is this a normal trouble shooting procedure?? Looked at the Great pictures and wish list of your Z Rusty.
