Sticky Steering Ring Fix
Man - I always thought I was lucky and never had the Z4 sticky steering - even though I read about it before I bought one. I thought it was at slow speeds only and so warmed this car up and drove it in circles in the lot before I bought it looking for it and nothing. And nothing for year of ownership.
I got my alternator and drive belts put in earlier this year and finally drove it to work on one of the warm days we had last week. It got to 85 that day and I decided to take the long and curvy road home - and man my car felt possessed. I was not sure what was going on and then got to remembering that and googled it and read about the grease zerk trick, but then stumbled onto the adjustment ring German post on the matter. I had never seen that before. https://www.zroadster.com/forum/thre...5#post-1943088 I took this on this weekend an no joke - it is not easy on the US cars. It is only 2 bolts to loosen - but they are buried and hard to get to - but I will say I think this fixed it 100%. I'll have to wait for another super hot day to know for sure, but I think I had been feeling the effects of this for awhile now as the steering felt MUCH better even on the cool day yesterday when I tested it. Seemed to have manners again. I felt it was even dangerous to drive the way it was it was so stiff and clunky when hot, but this fix seems to be spot on and worth the PITA it was to do it. Take it from me - you have to disconnect the battery anyway - so just take the drivers seat out from the beginning. You are going to probably spend some time down under there doing it, so get comfy. My front one was situated where the only place the allen wrench would go in, was up against something that would not let me loosen it. I had to cut the end off and then bend the allen wrench enough to give me clearance. Should be a 20 minute fix if not for the placement struggle. If you are fighting the sticky steering and not enjoying the drive you once did - I highly recommend give this a shot. Not a hard fix - just frustrating for sure.

So BMW apparantly reads those forums They call it a fine adjustment. Any BMW dealer can do this job (if they know their trade)

ALSO, it appears to me that metal shavings might be left in the steering tube after drilling. Wouldn't that cause a problem? |

So I started with this one: https://www.bimmerforums.com/forum/s...y-Steering-Fix Which lead me to this one: https://z4-forum.com/forum/viewtopic...78250&start=15 I can't seem to find the link to the german forum that found this fix, but they had some decent pics. The fix is 10 year old child easy to do.....the problem is where it is located. It is way under the dash and very tough to get to. Unless you are a little monkey - take my word for it and just unhook your battery and take your front seat out (no need to take the seat belt off - just stretch it out and sit the seat right next to the car) so you can relax and lay on your back while you cuss the galaxy as you try and get that allen wrench into those 2 damn bolts. I bough a few at harbor freight so I could bent the piss out of them to get them where they would fit in AND leave me with room to loosen the bolt. It sucked for me. If it was on a bench - it would be a 3 minute fix - the bear is getting at them. You can see them easily - just getting to them. If they were a regular bolt it would be so much easier. Good luck! PS - I found it - google translate will translate for you, but the pics kind of tell the story. https://www.zroadster.com/forum/thre....59821/page-75

If my trusted mechanic can read, perhaps I'll just give him a go at it. At my age, I just don't have the flexibility needed. Besides, it can now wait 'til next year. No more 90+ degrees this year.

I'm 50 - and I still managed, but it was not a joy. Like I said - would be super easy if the access was there. In fact if it was I would go back in and tighten mine back up just a shade. I errored on the "too much" side so I would NEVER have to do it again, but wish I would have went 50-75% of what I did. It is still LOADS better - even better than before I noticed the sticking, but maybe about 10% looser than I'd like. I'm used to it now, but the first few aggressive drives took me a little adjustment to get used to it again.

He put yet more grease in the steering system and EUREKA VIOLA !!!! It worked. As a previous thread noted, it may not be quite perfect, perhaps 90%, but no more notchyness. I can now cruise down the hiway with only one hand on the wheel. Long distance driving is now a pleasure!!!

So I just picked up an 06 Z4 3.0i this past Tuesday. Drove it 45 miles home with the top down and LOVED it. It sat outside Tuesday night/Wednesday day (90+ degrees). Got in it to drive to have it inspected and walla! The sticky steering problem! Guess this will be the first fix I do to it!

Hi all
There are several comments here that the steering ring fix is documented by bmw as an authorized way to address sticky steering. I have called my local dealer here in Canada and the dealer in Fort Myers where my car came from and they both claim to know nothing of this. Can anyone point me to something official from bmw on this so I can show them that there is a procedure and here are the details of the “fine adjustment”? |

My question is, how do you know how far to spin the ring? I did it to mine last year, but I may have gone too far and it came back this year... or perhaps I didn't go far enough?

If there is an official BMW repair bulletin / procedure to address hot weather sticky steering, and we can get to see it, that and other questions should be addressed there.

I know and thanks.
But I have spoken to two BMW dealers in two countries today and they both say this repair does not exist. Do you perhaps have a BMW reference number that I can throw at them so they can (along with a good strong cup of coffee lol) look this up and get familiar with it? |

I don't work in the automotive business, but I would die of shame if a customer would tell me things about my own professional expertise that I didn't know Especially if that information just floats around on the internet....

Okay so here is what I have found. As I understand it, this procedure is what needs to be done, except that you do not remove the steering column from the car:
