My Speedo on my cos stopped working under acceleration so i replaced it with a new one only to find i still have the same problem, Ive checked the cable is turning the odometer and it does fine. is it possible the output from the gearbox can be faulty?

Very frustrating!

Cheers

 

take the cable of the back of the clocks and see if spins(when you drive forward) if it DONT then it's the speedo drive gear gone in the g/box nla part

if the numbers are working then it MUST be the clocks themself m8!

all the above is on a 2w/d and IF the cable itself is in good condition of cos
