As it says above I'm having problems resetting the trip counter, it will no longer reset back to zero using the usual method. Anyone else have this problem or know a way to fix it?
Try dissconnecting battery , hold the live and earth cables together for 10 seconds or so to drain any capacitors that will hold memory , dash should re boot up then
Is it an early (2007/2008) model, or one of those new fangled 4V jobbies? The early ones had a recall for a software update of the dash to fix trip counter issues.
