Hi everyone was just wondering if I could ask for your advice?
My car's speedo has started to do some weird things and Im not totally sure what to do about it. It was fine since I've had the car which has been nearly a year now but just recently the speedo has started to wild'ly over read. Ill be doing 3,500rpm down the motorway and the speedo will have gone over 140mph and be pointing straight down, almost going all the way round. When I stop the speedo will still be reading 70mph and then when I turn it off the needle shakes as it falls back down to zero when the power is removed. It not like it doesnt work, it goes up as normal when you pull off but any increase in speed sends it even more skyward.
My car is a 99 1.6 8v Mk4 any help would be really really appreciated!
