Xsara Picasso reluctor ring? ABS Issue

Post by thebrasso »

HI All, I'm currently having an issue with my ABS, Last weekend, I has my wheel bearings replaced by a fried, and I am now getting the ABS Malfunction error, i have a feeling that one of the ring may have slipped/broken.

My Xsara Picasso is a 1.6hdi 2007 and having looked at them in motor factors, which ones do I need and how are they fitted Is it easy job? How are the secured to the driveshaft?

and is it do able by a weekend mechanic on the driveway.

Any information would be greatly appreciated, and I thank you all in advance :-)

Measure the diameter & count the amount of teeth/spaces on the originals to get the right ones.
Its not unknown for them to break off but have you actually checked them, could be damaged sensor too?
Don't think Citroen sell them separately for this model, if they are separately replaceable then you normally heat them up in the oven to expand them & just knock them onto the CV joint.

Thanks for your reply's, it was the front wheel bearings that were replaced.
No, I haven't physically checked them yet, I checked via lexia and its the drivers side front, just getting a quick head up as personally I reckon that if i have to replace them, it will be much easier than trying to remove the sensor as the bolt is very heavily corroded, Other than the obvious WD40,and letting them soak, could anybody recommend a way to remove these?

If you can, give the sensor bolt a daily dose of Plus Gas for a week or so. This has the tag-line "Dismantling Fluid", and it lives up to this. I had to bleed the brakes of an elderly Xantia, and the bleed nipples looked very crusty. However, a week of Plus Gas meant that they came undone very easily.

Before you go for the reluctor rings I suppose you first should make sure the sensor hasn't been damaged by the bearing fitter, easy done.

If not already done, also check the reluctor ring isn`t split. If rusty, they can appear firmly fixed despite a break. The gap can then cause a change in the signal phase that upsets the ABS unit.

Quick update guys. Had a little inspection of the rings yesterday. Cleared the fault in lexia, once driven it comes back on. So looks like a faulty sensor. Off the week after next, won't be using the car often, so I'll put it on stands and start soaking the nut/Bolt in plusgas. Will report back once done

Just a quick one about the sensor, am I correct in thinking that the cable runs up inside the wheel arch and into the engine bay where it is connected via a plig in connector??

If it follows the way a Xantia had its' ABS done the sensor has a short (6" or so) lead that goes to a connector, where it then joins the main loom.
