Hi Andy
Thanks For your reply
On the mid level instrument panel its the item , bottom left of the speedo dial.
There are no running faults, it seems fine.
It was fine Friday morning, Friday afternoon there it was, lit up when the engine was running, I wonder if it could be that it hasn't had a descent run lately and is getting blocked up.
I'll have a g at the gearbox and engine oil tomorrow, thanks for the suggestion.
Regards
Geoff
