as I'm driving along there is an odd ticking kind-of noise coming from what appears to be behind the dashboard. Any ideas on what it is and/or how to stop it? Think it maybe the speedo cable...?

hi. i got a sort of rattely clicking noise from behind my dash, think its from the diles but not sure wether its the speedo, or the rev counter. not that this helps but your not alone. good luck.

its the speedo

i got it too VERY common prob..... nothing serious however, just turn the radio up

Yep, the speedo cable is the culprit.

20 min easy DIY job too.

It may sound daft but try pushing the trip button in ! I have had loads of customers in the past with such a problem,if that fails,then speedo cable is the fault.
