It has been dropping off to zero then mysteriously, slowly, returning to normal temp. Keep in mind that this happens at normal operating temps. Also, the coolant temp on the VW-Tool has been or seems to be stable. I think this might be a bad sensor for the dash (the gauges sensor if separate from the ECUs correct?), but was wondering it this could be my problem?

Thanks
