Kelly, I get a similar intermittent problem with the gauges on my Williams
Every now and again the oil temperature gauge will stop working, but then seems to spring back into life after a while. Been meaning to get it replaced, but I never seem to get round to it - anyone any idea where I can get replacements (at cheaper than Renault prices if poss)?
As regards the oil level gauge, mine only works when you first start up the car (or put the ignition in the start position). It registers the oil level (and is usually fairly accurate when compared to a manual check) then simply returns to the bottom for the rest of the journey - which kinda makes sense if you think about it.
Doubt that will be of much help, but I thought Id throw in my two pennies worth anyway
Cheers Mike
