Mot fail

I could be wrong here, (it has been known), but I think the rear reluctor ring is inside the handbrake drum, if you have rear discs

The sensor pokes into the drum through the back plate from what i could see... Might have been a ring in there but didn't see one..... But I also wern't looking for one.

Yep the reluctor ring is hidden inside the drum which normally protects it from the dirt/salt/assorted grime that kills the front ones

+1 - its part of the rear hub assembly for cars with rear discs and ABS. £45 for a half decent one at a LMF.

I thought the speed sensor was on the front wheels, cos when you wheelspin the speedo needle goes up...??

Speed sensor is driven straight off the diff, so yes!

Speed sensor in the context it was written above I think means the road wheel revolutions, so that the ABS ecu can make it's calculations.

Does it really?

Maybe not on full-mux cars - a few of us 6-speeders don't have the sensor and the speedo still works.
I did transfer mine, but I gather the nav won't work and maybe the auto door locks too, without it.

Ah yes, you're right....I was still in V6 mode where it does operate the speedo!

I should've remembered that Doggy, after having just done a 6 speed conversion on a Coupe. But I guess you'll have seen that elsewhere!
