speedo is playing tricks on me

[thomas_mk6]

hey guys only owned my rex for a week (94fd) and every now and then the speedo either dances around within 20 mph of the speed im doing or it just dies completely, is this a common fault? wheres the best place to start looking?

ive heard of them playing up a bit, i think its a common fault, on the od occasion, not very often mine will stutter as if it cant keep up when you boot it but havent ever experiened your symptons

Seems very common, mine was exactly the same.
 
Bought a new unit of someone on here, easyish to swap and now works perfect.

Yeah, common issue. I had to get mine replaced.
