Removing Steering Angle Sensor - Upper coupler

[tomrdy]

I'm planning to remove my Steering Angle Sensor through the firewall to replace the brushes.

Referring to Pelican Part's instructions, it seems that the only mechanical connection I need to disconnect is the upper coupler. Instructions state that I should be able to slide the coupling off the steering shaft as below:



I want to check with someone on the forum - is there enough play between the U-joints + steering rack to only need to release the upper coupler as all the references say?

The steering intermediate shaft will compress by four inches.

thanks raymond exactly what I wanted to double check

The Pelican Parts Z4 instruction manual is specifically for the ///M model, in a lot of cases it doesn't matter but as you know the M has fluid PAS not electric electric so has a different column and steering mechanicals. I don't know if the steering angle sensor fix will be different but it may be worth checking on TIS for example.

I refer to Pelican instructions quite a bit you have to watch them, on the Q&A at the bottom of the page you linked to they suggest the guys power steering fluid pump is faulty.... on his 2.5 and link him to the pump replacement page. Lets hope he didn't order the parts before he started the job

The shafts at least, apart from one of the joints being a different size, are the same on the M model.

Yup thanks noted already that its for an M! The only difference I've observed regarding the sensor is that the non-M (at least mine), doesn't have a slip ring on the end, making it quite easy to get the sensor off it's mount.

I was planning to replace the brushes + plate with the heavy duty unit made by a guy in germany - but he's unable to post out due to covid. Considering either making some brushes or ordering these brushes from China, taking the sensor out and hopefully slotting these in - but again, not sure on how long postage would be though it's 1/5 of the cost of the heavy duty part.

I'm most likely just going to open the sensor back up in-situ as I did before and cleaning it again. I'll bend the brushless prong up a bit more to TRY and use as the contact point and properly lubricate everything. It might wear down the carbon resistor tracks a little but with covid not much driving will get done anyway .

These are well F'd



If someone has an old sensor out... would be interested to know if those prongs can just be yanked out and reslotted easily or if there's some adhesive to it. If they're removable and refittable in the awkward space within the footwell, it could open up possibilities for a potentially "easy" and cheap fix for this issue.

Mine is for sale on Ebay - I cannot actually see any problem with the brushes but the unit had zero output.
Cost me £250 for a new one.
