Sticky steering back again!

Last year had a go at sorting the sticky steering on my e85. It’s been fine until the last 2 days of hot weather 18 to19 c. When I “fixed” it, someone previously had tried the grease nipple idea, someone else had moved the “washer?” 5mm. I moved it another 5mm. Shall I move it another 5mm or try the grease method? What’s best to do please? Thank you in advance. Mike.
 
It is more often caused by the different metals expanding at different rates. Moving the spacer ring a bit further will lift the worm gear of the motor slightly up off the gear on the column and should stop them constantly pushing against each other. I would try that first

Thank you enuff_zed, is there a limit to how much it can be adjusted? We are out in the car during winter almost every day and I worry that in the colder months it will feel too loose. Mike. :thumbsup:
PS did the face lift have this problem, I don't seem to see their steering being complained about having the sticky feel.

I cannot guarantee you won't have to move it back a bit in the winter.
All sorts is written about people wanting the 'uprated' facelift column, but I've never found a difference and I have adjusted a couple of facelift cars as well.

Another 5mm sounds a bit drastic Mikey, 2-3mm max I’d think..? Enuff…any thoughts..? :?
I usually do 8mm on the first tweak. So yes maybe 2-3 more to begin with.

My facelift 3.0si is bad enough I'm considering adjusting it, the prefacelift 2.5i is fine in sport mode when it's hot out so I've never bothered adjusting it. I'd say my facelift is worse than the pre based on that :roll:
 
There is a limit each way to how much you can adjust so you can’t go over

From memory it’s a good 20-30° of motion in the adjuster so plenty to play with

Oh, that’s a bit annoying, twice a year. So no point thinking about a face lift car then.

So basically BMW made a complete mess with the steering :thumbsdown: :headbang:

Get an m

It’s hydraulic

I was quite tempted by the almost-complete hydraulic conversion parts someone was selling recently, just came at the wrong point in the year (I'm currently taking parcels in for a suspension overhaul.)
 
Weakest part on these Z4's IMHO, even when not sticky you dont get the feel/feedback like hydraulic. Anyone driven one were the elec motor isnt working? interested to know how it feels? I have a friend with a TVR Griff with no PS, would it feel fine once on the move?? just curious

Once above about 20mph it is fine. But if you have to stop at a roundabout, for example, then jump out into a gap, you'd better be ready to avoid the island in the middle. :rofl:
I drove a 3.0i back to Norfolk from Shoreham-by-Sea, then a 2.5i from Southampton back to Norfolk. Wouldn't bother me to have to do it again.

Interesting - thanks enuff-zed :-)
I am off an age when PAS was in luxury models only
Thinking about it, when the steering motor fails you are then trying to turn a worm gear from a cog, which doesn't work very well. I wonder if it would be lighter without a motor fitted?
