Speedometer Not Working

I recently bought a Series 3, however the speedometer never worked, i thought it might be the actual head unit but it wasn't that, i checked the cable from behind the dashboard and it doesnt spin while i'm driving. I have replaced the cable and have unbolted it several times fro the speedometer drive. Anybody think of anything??

Hey
I had that problem when i bought my series 3 recently, although that was because the speedo cable wasnt actually there. I just bought a new one and fitted it and it worked fine, so assuming the new one you bought isnt fautly, i expect its something to do with the unit inside the dashboard. can't help to try and take it apart and give it a clean even if you can't see whats wrong with it. But dont blame me if it falls apart

My Series III Speedo also doesn't work.... It was a few years back when I bought the vehicle. It was working, then it just stopped. Haven't really looked at it ( in 2 years ).. So can't really offer anything useful here, but I would be interested in how you get yours working as it might give me some ideas....

Hello,Had the same problem on 88' series three. The speedo drive in the gearbox was / is made of plastic and rounded out so would not drive the cable. To fix it i squashed the end of the cable inner with a pair of pliers and made sure it engaged with the plastic drive. All mended!If you have checked the cable and it okay then it must be a problem with the drive from the gearbox - so have a look down there.Good luck

I'll go along with what Buckle says. I've got a similar problem myself at the mo.

Definitely sounds like its the fault of the drive in the gearbox to me. I wonder how you get the little plastic socket out to replace it. I've also got the added problem of an overdrive being in the way!
