C5 Instrument Display

Hi all

c5 18 51 plate 60k

spedo,revs,fuel,temp gauges all keep going to park position for 2 to 5 seconds then come back to running reading when vehicle is driving,does not afect the car in any other way and runs fine. fault is intermitent and only happens 2 to 3 times a day. no trouble codes detected and no ignition lights on when the needles drop. got a feeling its the instrument cluster just looking for confirmation or a direction to start at. Its a problem that could be lived with if it wasnt rented out but with the price of fuel the look on the drivers face was fantastic when he thought customers were going free as no speedo=no meter=free taxi ride

I would say its a resistor overload/over heat issue because it comes back on or simply needs the connectors on the back of the dash cleaning with electrical spray and see how that goes

many thanks will do that tomorrow. now just getting another c5 through this site anyway its 2.0litre petrol y reg. And the belt has snapped is it a head off job or like on some ive worked on are the rollers that push the valves down designed to snap as ive had a quick look and see that the cams will come out without having to remove the head. I cant do a comp test as i dont have the extension piece to go down the spark plug port

many thanks

if you have ever done a vauxhall vectra its a similar job and not that bad to do ( much better than the diesel engine because its cheaper ) best thing to do first is to fit a new belt and tensioner ( the cams come out without removing the rocker cover ) sounds like either the cams have snapped or the bearings holding them down came loose and that's good news because chances are the valves will be ok so a good investigation is worth while
