Citroen Relay Spedo/temp gauge not working.

[Chris51]

Got my MH taxed from today as been on sorn since Nov ...went ok but for some reason the spedo and temp gauge dont work.Tried the fuses on drivers side r/h below dash but all ok ...any ideas ?

Check in the handbook as it could be one of the fuses under the bonnet.

Isn't there an issue with the Citroen's and Fiat's ECU that can be caused by low battery voltage that requires sending the unit off to Crashdata ?
If you've had it Sorn'd, have you kept the cab battery charged up satisfactorily ?

If it is not a fuse problem Sometimes removing and refitting the multi-plug on the back of the speedo/ gauge assembly can sort this type of thing, if a poor connection, but it is possible that the motors that these units have in them for their operation have seized, if so , a company called Cartronix should be able to help if you contact them.

I think that the problem that Crashdata sort out is with the air-bag ECU fault (warning light problems etc)

Battery has been charged by solar panel on roof and gave it a good run out ...seems strange that the spedo and temp gauge are not working but fuel gauge etc are ? I know where the fuses are in front of drivers right knee on dash and under bonnet r/hand side but is there any more fuses anywhere ?

If your Citroen is a later model with electronic systems , The motors (ECU operated) on the gauges and speedo can stick when not used for some time ,Cartronix may be able to let you know if there a way to check/fix this problem if this is the cause.

Have tried all fuses under bonnet and d/side bottom of dash ...battery has always been fully charged and refitted dash plug ....looking for a s/hand console now.
