Official BMW Procedure.

Well, isn't that interesting. Looks like we've been doing it right. What's the date of this TIS update? Is this old information, or something BMW's just discovered?

Interesting find.
I checked with my official TIS version that sits in ISTA-D. That is from 22-11-2014 (ver. 3.46) so quite old already (for ISTA terms, the old tis was from 2007). That version also has this page already albeit slightly different. These is no distance listed for D (here D=5mm), but you can read the 5mm on the picture with the caliper.
I first mentioned the method here on 19th of june 2015: https://z4-forum.com/forum/viewtopic.ph ... 3#p1153983 ; by then lots of people in DLD/NL had done this mod.
On the german z forum they first started experimenting with it and reporting it around may 2014:

It never came up in me to look it up in the new TIS because the old one obviously never mentioned it.
Maybe the new tis has more answers to other previously not displayed/solved problems.

Yeah this is a great find, glad to see we're on the right track. Might be worth sifting deeper into TIS and see what else is there.

Yes, thanks for the heads up Guidok I did mine in June 2016 after reading your post. I initially moved mine 5mm but increased it to 10mm a few months later. There is no stickiness at all now but I can still 'feel' a difference between cold days and hot days (or when the heater has been on for a while).

In theory as this is a TIS entry now (or apparantly has been for a few years now), a dealer can do this repair too. Albeit TIS writes that the steering column has to be removed, which costs time (and money). Probably to not frustrate the more clumsy bmw mechanics.

Is this thought to solve the steering wobble that many experience at motorway speeds? Assuming other aspects such as balancing and FCAB replacement have already been addressed.

You mean the tramlining effect where the car is steered into the ridges of the tarmac caused by heavy lorries?
Thats mainly solved by ditching the runflats and maybe in limited effect adding rear trailing arm limiters (or rear trailing arm bushings that have the limiters build in).

Sticky steering is more an effect where it seems that a small magnet holds the steering in the center position and you have to break the steering wheel free from that magnet force before you can steer.

Solved mine after trying everything else. You have nothing to lose.

Just had a go at this, but can’t get enough leverage on the bolts with my hand up inside the dash. Mine’s and e86 and it has allen bolts, not torx. I’ve got an allen bit, then universal joint, short extension, then T piece (all 1/4 inch), but I can’t get enough leverage on it. There’s not enough room to get anything longer up in there either. I suppose I’ll have to take the whole steering assembly out if I can’t find a way.

Any advice?

so who's setting a stall up at ZEDfest to do this for people !!!

Ha, long as theres a free osteopathy session after Takes me about 20mins to make the adjustment.

I can vouch for this fix. Done it on my coupe a while back and it's transformed the steering. Feels so much more planted on the road now. Great fix OP!

I’d book for this done at zedfest!

You had sticky steering on your coupe?
Thats quite rare to have it on a FL car.
