Today my OBC just went blank out of the blue. The fuse is fine (I think) and the buttons are illuminated. Seems a bit odd though for the whole display to go blank. Any ideas?

Also, my temp guage need a little flick at the plastic cover to get it off its rest and reading, sometimes it bounces mid journey. Any ideas about this aswell?

Thanks

one of the backlight bulbs has blown, if you look closely you should be able able to see the display very faintly.

you need to remove obc from dash and pull out the white plastic holder, you will then see the pcb with 2 bulbs on, you then need to solder in new bulb(s) the bulbs you need are 4mm 6v from RS ( www.rswww.com ) order code : 586-374 iirc they are 59p each

That's probably it for the OBC.
For the temp gauge, tighten the nut on the back of the cluster, directly behind the temp gauge.

Mine gone funny too.. It shows up blank, BUT you can't change the time or date.. or even move to the temp screen. It just sits at 0.00 and 1.01 Can't change it or anything. Help.. I just got my temp sensor in today.. and now it doesn't work!

Try disconnecting the battery for a while (hr or so), if that doesnt work, try removing the plug from the rear of the obc and re-connecting with ignition on. Then i'm afraid its probably a new unit, mine went the same way! (Oh well only Ԛ£500 from the dealers - seriously! :eek: )
