I made a mistake, it is the blue sensor on the Activa that needs replacing.

The ABS sensors on the Xantia are quite a tight fit in the hub. On the first ever Xantia V6 I had in 2007 (R266 DUR) I had the same thing happen the day before it's MOT. I fitted the new sensor and left the bolt out. I didn't have any problems with it within the next 6 months that I had it for.

I have sheared off that bolt on a couple of Xantia V6s. One was drilled and tapped to original size, the other, in a rush for MOT, with no tap available, was drilled out and secured with a bolt and nut, but I think access for the nut was fiddly.

Sorry to see this happened to you Simon :(

Last time I had this happen I whipped off the hub, drilled out the remains and retapped the resulting hole...

I found this easier than any other sorts of 'faffing about' trying to extract the stump of the stud...

Although to be fair, Jim, unless I am mistaken, we were changing the wheel bearings anyway on that one... #-o

Indeed we were Mike :D But it improves access no end for the stud job though ;)

Thanks for the advice everyone, in the end I've decided to try to drill and tap the hole carefully back to the original thread size - on the theory that the bolt will be a lot softer than the hub casting, so that if I'm careful drilling the centre hole the tap should remove the softer material left over from the bolt and fall into the existing threads in the housing and clean them out. I found a reasonably priced tap set that includes a starting tap here:

http://www.avontapdie.co.uk/taps/tap-se ... x1-tap-set

Because the brake disc would foul a conventional tap handle with a standard length tap I've ordered one of these ratchet collet tap wrenches:

https://www.amazon.co.uk/dp/B004GCIONI/ ... 21_TE_item

It's about 100mm long but even if it doesn't quite clear the disc the ratchet action will come to my rescue! I figure that a tap and a ratchet handle like this will come in handy again one day.

For bolts I found an online source of 6x1.0x35mm bolts that should do the trick - I feel a bit silly walking all the way from work to Citroen glasgow (about 25 minutes each way) just to buy one fairly standard M6 bolt from them. :rofl2:

Fingers crossed...

If the sensor is tight in the hub, I'd probably just put some loctite on it and shove it in. But then I am known for taking the easy road (aka bodging it!).

The original bolt is more of a stud with a nut in the middle, but not sure how critical that is to the fitting of the sensor - you can probably make do with a spacer made of nut(s) and / or washers to get the shoulder in the right place.

Are you sure it's supposed to be a stud ? The bolt that broke off is an M6 x 1.0 x 35mm bolt with a hex head and a captive washer. Definitely not a stud.

The sensor pushes directly into the hub, then the head shield goes above then sensor then the bolt with its washer. I couldn't find any bolts with captive washers but did find bolts of the correct size which I'll just add a washer to.

Yeah I was looking it up on service citroen too and was thoroughly confused by what I found. What they show doesn't match what I actually found on the car. :lol: That's one reason I decided not to get a bolt from Citroen.

As long as the ABS sensor and the heat shield is held securely Simon, a suitable fixing can be fabricated. A stud to secure the sensor with a tapping in the head to take another small stud, possibly with spacers, to hold the heatshield will be good...
