Stick up an down steering column fix...FAQ
I am still slowly going across the car, replacing those convertible hoses.
Anyways, while I am at it, I fixed my sticky steering column adjustment servo. Very easy fix, costs nothing!
If someone is interested, I could put a quick how-to together, ofcourse it would be nothing fancy, like Reverend would make
There will be no drama, no talking into camera and absolutely no nudity

Ok, here it comes!
What causes this issue is Bosch part, believe it or not.
Motor that controls the up and down is mounted right under the steering column (see picture), on one end it has little drive shaft, on the other it has potentiometer assembly. This assembly is very hard to spin and this is due to one very agressive spring washer. What happens is, when you try to adjust the column, motor jerks for a split second and then, due to excessive load, relay powers it down. Helping steering wheel up, or down does not help either, because it is driven through a worm gear... anyways, long story short:
1. Take off kick panel above the pedals, it is 2 8mm bolts, maybe 10 mm.
2. Take off motor-reducer aseembly, below the steering wheel. It is bolted on two allen style bolts, I think they are 5mm.
Please note that there is a shim, under motor assembly, for what reason I do not know, I did not re-install mine, because bolts are rather short, so I decided to give them couple more threads deep.
3. Unplug electric connector, it come out easy.
4. Slide off an open potentiometer assembly hosing, it has one screw and 2 little tabs to pull. It is Bosch made, so plastic is very strong, nothing breaks.
5. flatten the darn spring washer, or remove it of you like, I flattened mine with my fingers. You will see how much easier it will spin, after you put it together. Do not forget to add more lubrication, if you must.
6. Re-assemble motor assembly.
7. Bring the steering column up, or down manually, by spinning little drive shaft by hand. Now, connect electric cable to motor assembly, check if it works and then run it up, or down (with column adjustment knob), depending which way you moved the column earlier.
8. Slide motor end of the drive shaft into the column end.
9. Reinstall motor back in place, with, or without shim.
The end!

Just so I understand...This is a fix for my steering column up and down movement. When I remove the key, my steering wheel go all the way in and all the way up. When I insert the key the wheel moves out, but only down a little. If I hit the memory button many times, it will move to the correct place and "ding" This is what we are talking about, correct?

There is also a manual adjustment that will work now..

True, I need to clean it. It looks a bit crazy, because I worked on XJS last fall and you know how that goes...plus we had whole family of deer coming into our backyard, eating tomatoes and grapes, had to watch for them.
I was actually planning to organize it and paint bench top with nice epoxy paint.
P.S. I do good work though.

Added to my "to do's" ! Thanks for the post Mish! As you worked on this was there any place to "grease" the joints?? Mine started to make noise when it was going down and now sometimes it will make a grinding noise when going up. It is not all the time but it is temperature sensitive when it does it. Cooler temps are more likely to make the noise. I guess it could be just the motor doing it too but then it would do it more often and up, down , in or out i would think. Anyone else have a groan when the steering sets itself???
