You get what you order, the complete hubs p/n starts with TAY and these bearings are with TAD ... albeit unfortunately some sellers are mixing things up these days... you have to replace this bearing on your old hub
yep, my bad! just trying to figure out how to use them
Since he last time, i havent replaces the sensor again yet but i did a quick bleeding (not used nanocom,maybe that was a mistake) and replaced the battery. Went for a 500mile+ trip with a mix of motor ways and offroading and no amigos, until the last day the amigos came back was looking at the inputs from the nanocom (at idle) and noticed these values:
Inlet Valve (V):
Front right 0.03
Front left 0.01
Rear right 0.03
Rear left 0.01
Sens (V)
Front right 2.17
Front left 2.15
Rear right 2.17
Rear left 2.15
Would this be whats responsible for the intermittent errors?

Those readings are within accepted limits, what's the fault code?

seems that we are at square one again while some important things were missed.... it was already mentioned first time but you didnt confirm if you tested this or not and if not you better do it now: clear the code then unplug the left front sensor go for a drive untill the amigos show up again and see what code you get then
also which hub did you replace, only the front right?

i had replaced only left side hub. when i unplugged the left side i immediately got an error for the left side. i just managed to obtain a slabs ecu for testing, im curious if the idle values will be the same, failure that i ordered a full set of calipers (i have an annoying squeaking/almost like it is grinding when the brakes warm up that did not go away new pads). So i will re-bleed using nanocom and see if that makes a difference. the painful bit is that it will take weeks before the amigos reappear

seems like a weak contact somewhere along the LF sensor's circuit which occurs now and then...uness it's a dry joint in the ECU on that path, let's see what happens with the other ECU
tried another ecu and its the same, although tbh i have no way of knowing if ths is a good ecu or not, but behaved similarly. the wiring seems fine, i will try to replace the wheel hub. however im noticing squeaking from the brakes, im wondering if it has anything to do with it!
So latest update, i have now replaced both front wheel sensors with the Moog bearings and sensors and have been three amigos-free for a couple of weeks, so im hopeful. I also replaced all the calipers and carrier pins. All calipers seemed in good condition. Only one of the rear carrier pins was seized, the rest seems good but decided to replace everything anyway. As for the front hubs, the ones installed seemed in good condition, they have no play the sensors do not seem to have any markings either so im at a loss what actually was wrong

I have never been able to discern any play in any of the three hubs I have replaced but there must have been enough to bother the sensors as the new ones were fine. This has been the experience of some others on here too.So latest update, i have now replaced both front wheel sensors with the Moog bearings and sensors and have been three amigos-free for a couple of weeks, so im hopeful.

In many cases the play is not noticeable in the wheel or hub, the problem is the reluctor ring inside which develops a wear and a play which doesnt affect the bearing but it mixes up the sensor's signal.

Is that a fact? Never knew that. How on earth can the reluctor ring wear? It doesn't rub on anything does it?
The "old" ones were only a few months old when they started giving errors (britpart oem option). So i m guessing its the cheaper britpart design? Not sure , hopefully i remain 3 amigos free

Crossed fingers for you.The "old" ones were only a few months old when they started giving errors (britpart oem option). So i m guessing its the cheaper britpart design? Not sure , hopefully i remain 3 amigos free
Still wondering how a part that only connects electronically with the sensor can wear.
another interesting thing is that when i only replaced the left side hub (which was the only one giving an error on nanocom) nothing changed. after i replaced the right one too it fixed the problem. I suspect bearings from different manufacturers give slightly different signals which might be interpreted as one of them being bad. i really do think at least one of the hubs is still good, so im keeping both as spare.

This is sadly not uncommon.
It happened to me after I took my D2 to an Indy to have the 3 amigos diagnosed. They told me it was rear left so I replaced it. The 3 amigos came back. I went mad at the garage after a smaller one man band indy diagnosed it as the rear right. I swopped the rear right half-shaft for a secondhand one and it was fine after that.
I don't have a Nanocom but after this caper I bought a Foxwell and it doesn't mix up the sensors on the same axle as others do. (I have been informed that Nanocoms used to do this before some sort of an update.)
So I hope you haven't thrown your left side hub away as it may in fact be OK! I kept mine as a spare and fairly recently replaced a hub with it. It is fine! But I think your right one probably is duff.
no, my nanocom does not mix up the sensors. i had tested that by disconnecting one of them to make sure it throws the error on to the disconnected side.

Then as you say, a mystery.
