Your "Disco 2 said" ? So, which diagnostic machine said this? Some get the wrong sensor for a pastime, I know this cos I have been that soldier and ended up changing both rear hubs to cure one sensor problem. Only 2 out of the three different diagnostics got it right, my Foxwell and one other 4x4 garage. Sieraferry knows about this and it is one of the much-talked-about diagnostics that cannot be trusted.
If your wheel bearing is just a tiny bit out it'll throw the three Amigos, even if the sensor is working properly and inserted properly. If you can, try borrowing a known good hub and sensor off someone, or even getting hold of a secondhand one, then try it on each end of the axle in turn.
Don't know what trick from the Tube you used, but I don't think there is much of a trick that can be used successfully to get rid of the three lights. I tried all the tricks I could find, none worked. To get the three amigos to go away you do have to delete the error codes via a diagnostic. Oh, and then drive the car a bit to get the last one to go out.

I'll say it quickly, before anyone else does, have a look at your Haynes or RAVE manual. It's some sort of electrickery box of tricks.

REALLY???
I've got a box under my front passenger seat but I don't have SLS. I took it to mean in the interior of the car, by the way. I also have a funny feeling it is possible to find two boxes in there. Then there is the disc player of course.....!
