I was told by the local VW shop owner that normal cyl head temp guages for a VW ( I'm assuming he meant VDO guages, he didn't say...) ran from 100-600F. I got the Autometer guage, that runs from 100-340F. He said that the head is probably running at normal Operating Temp, but that my guage couldn't run up to that high a temperature. I would like a second opinion on that one, though
