Link to a PDF containing a few details on the removal of the Brake Position Sensor <<< More likely the problem with my car:


Although this is for the V70XC I think it's not far off the 850 sensor removal:

That was rather easy! I was expecting some really awkward design just to remove it.

So here it is, my position sensor removed from my brake servo:

Now here is the ultimate question.

How do it get inside the damn thing without breaking it? (If not I'll replace it with a second-hand one)

Just a few photo's on how to remove it:

I used a flat head screw driver to pry open the metal clip. The first picture shows the clip already half off. (Only for photo purposes)
I don't believe you really need to take the whole metal clip off, just pry open enough to pull out the position sensor.

The slovak way seems to be to pry it open and stick it back together, can't think of a better method.

I think I have cracked it (Not literally broken it) I have half solved the problem.
When I had the position sensor removed I rapidly pushed in the silver rod (See the photos below) in and let it release itself (It's on a spring). I done this loads of times and tried to blow through the front where the rod is located. The gap is tiny & my blowing probably did nothing but I think the constant pushing in & out might have fixed it for the mean while.

See, looking at that Slovak website I noticed all the metal shaving from the pc board. I thought that if I couldn't open the casing without breaking it I might as well try to shake away those shaving by vigorous movement. This might only last for a while but at least my ABS light has stayed off, so far. I do understand it is only early days, so I will come back with a definitive answer later next week and so on.

So, if you don't want to break your position sensor casing, just give the rod a good 'thrashing' in & out! (Don't try to break it in the process)

Well then, I have also fixed my Stop Light Switch... I hope. If anything the sensor is now setup more precisly and I have adjusted it to be more sensitive!

PDF attached. (Click the links)
Once opened scroll down to Page 22. (Pedal Sensor)
AntiLockBrakeSystemAndTractionControl.pdf

If that doesn't work try the other Word document I've attached where I have copied the info from the PDF document.
Pedal Sensor.doc
