Golf Diesel

Having trouble with the dash on my mk1 as the fuel/temp gauges and oil battery and indicator lights don't always work, think it could well be the foil circuit board on the back as the wiring is fine. my dash has the anologe clock on the right ,beaing a diesel has the glow plug heater light in the middle, a few Diesel caddys had this dash. Anybody got one for sale ?
