So glad I joined this forum!!..I also have the "twitchiness" on the steering. I thought initially it was wheel alignment.So took it to BMW for it to be checked but wasn't out by much.
I would really appreciate some help with this PeteWard. If the offer is still open?
Hi. Having driven the car more, I was maybe a bit hasty regarding the 'repair'. Yes, it's better, but the twitch feeling has only been dampened. I made another adjustment, but have got to the point where the steering is starting to feel too heavy. After all, this hasn't fixed the issue... now thinking of selling the car, fed up with it!

Sorry to hear that, have you replace any of the other steering components ?

I think you might feel a slight improvement from making the adjustment, but I can't seem to completely dial out the twitching. Eventually, it just gets really annoying again!

The only thing I changed is the tyres, ditched the runflats and put Eagle F1's on. It's had a Hunter KDS alignment at Sytner in Leicester. They checked the steering/suspension components and told me nothing needed replacing. It's only done 42,000. They mentioned a very slight buckle on the front nearside rim. Maybe that's the issue, but at £800 per rim, it would be an expensive stab in the dark. Maybe it's the tyres, I've read that the Z4 is very 'tyre sensitive'. Again, expensive to experiment with. I might just trade it in against a newer model.

I've had issues with buckled wheels myself. The Z4 is the most sensitive car I've come across for its steering feel.

I paid a local alloy place to straighten my wheel, cost me £75.

Or if you have a square wheel setup try the rears on the front, or see if you can find another pair of front wheels to try.

Agreed, it feels like the steering wheel needs constant attention, it's a real downer as I love everything else about the car. 

I looked into having the rim straightened, the places I spoke to said they'd need it for a couple of days, I'd struggle to get about. Maybe I could find a work-around for that.

I thought about swapping, but have 225/40/18 front and 255/35/18 rear. Finding a front pair to borrow for an hour would be useful, but not sure how I could make that happen. 

Thanks for the suggestions.

Evening, all. After reading through another handful of related forums today, I picked up on a few people saying that the Eagle F1 Asymmetric 3's have particularly soft walls, so I tried something new... I normally run 31psi front and 33 psi rear. I decided to try 38 all round, and it's made a big difference. The car immediately felt more settled. I've just taken a drive down the stretches of bypass where the twitch was at its worst, and it was far steadier. I think that a combination of the gear adjustment and psi change has made the difference. I may try loosening the wormgear a touch and dropping the fronts to 36, just to see what happens. But for now, I've finally got a setup that I'm happy with. Let's hope I'm not back on here in 2 weeks, moaning that the twitch has returned.

Ultravox, I'll happily help you with the gear adjustment, if you still want to try it.

Cheers.

Just as an FYI for anyone is interested i tried this today with the halfords star / torx spanner (E12 i think i used) and no joy - you really need a flexible headed ratchet spanner to get at these. so a wasted hour or two for me I'm afraid. Currently looking on ebay / amazon if anyone wants to fire a link for something known to do the job. :x

This did the job for me


Look at this on eBay
https://rover.ebay.com/rover/0/0/0?mpre ... 3420748741

I used the ratchet end on the front bolt and the normal end on the bolt nearest the steering wheel (the ratchet housing was to bulky the get onto the back bolt).

hmm - not available in 8mm currently. i was looking at https://www.ebay.co.uk/itm/PFC08-8mm-Ex ... 3520949781 but suspect it might be too bulky

I've done a few cars now and have never needed anything but a straight spanner. Are you adjusting the steering wheel as required by releasing the reach/rake adjust lever on the column? If you don't, access will be almost impossible.

yup dropping and pulling it - guess with the star / torx i just cant get the leverage required to crack it as i can just get the spanner on. i think i wasnt very clear in my inital post - i can just about get the star head on the bolt itself but without the ratcheting action i just have nowhere to go with trying to loosen it off ( hope that makes sense). i think a combination of longer spanner and ratcheting action will do the trick
