just like to know is that a common fault my t2 is x reg year 2000 has lcd dash now that part works fine but the speedo plays up sometime i.e sticks at 30mph put foot down and still reads 30mph then jumps up then its ok for a while but also when i use tomtom it reads 5-8mph less than speedo but in my old car it read 2mph faster than the cars speedo does that make sense:augie
