My speedo only works when it feels like it (about 60% of the time).

Anyone else had this problem (90 GQ Diesel wagon Mav) and if so any suggestions. It's a real pain in the dot at the moment.

Is it more likely to be at the dash end or the gearbox end??

Thanks Hank

have a good look at the needle, it might be bent (caused by heat) i have seen two mq.s with this problem i
