2004 Ducato Temperature Gauge Issue
Hi to all
I've got a Bessacarr E445 on an '04 plate and the temperature gauge has gone a little haywire. The symptoms are:
Ignition on but engine not started: Needle on the gauge starts to rise even with a stone cold engine.
Ignition and engine on: Needle continues to rise but will suddenly drop to 'C'.
Normal driving: Needle will stay at cold and after a while the 'Engine coolant too hot' symbol will light on the dash, sometimes intermittently.
The problem has manifested itself previously by the needle going up and down the gauge. The problem then disappeared until we took the m/h to France recently on a skiing trip and the above problems occurred. I doubt if the engine was overheating abroad as the temperatures were consistently below freezing.
My fiancee's stepfather who also owns a Ducato based Bessacarr told me about the trick with disconnecting the wires to the gauge cluster as he was told the problem was a build-up of staic in the wiring loom, but this has had zero effect.
We purchased the m/h in July 2008 from a reputable dealer who also replaced the blower switch as it was faulty. Could a wire have been tightened incorrectly i.e not at all or is it something more serious.
Thanks in advance.
