Has anyone used a VDO Vision or Cockpit series 250F water temp gauge with the stock VW gauge sender? I was curious if they are calibrated the same. The VW sender says 125C, whereas the aftermarket VDO ones says 250F/120C. Shawn Wright http://members.shaw.ca/vwdiesels '88 Westy 1.6TD 5 speed '85 Jetta Diesel 1.6NA
