Cliic Option 1 is the correct fix for this issue. This thread may be long, but it has been created specifically with the aim of helping just like you, so I would recommend taking the time to read it, as it doesn't cost you any money. I could carry out the adjustment for you, but it would take about two hours for you to drive to my house.

Thanks Wonkydonkey, I will keep reading the thread and Might try myself the repair. Really kind to propose yourhelp but for sure $ hours overall of road would be the time maybe to carry it myself. I will let you know how it went :wink:

I have only had my Z4 for about 6 weeks at first although I thought the steering was twitchy it was not that bad however last weekend when it was hot I started to get the notchy steering where I had to constantly make small adjustments to keep in a straight line. I do not have heavy or vague steering and no vibration or warning lights.
It is a facelift 2.5si built in 2007 unfortunately it is in the bodyshop now having the front bumper painted so I cannot check while it is cooler. From reading this thread I plan to go through a number of checks before reverting to drilling a hole for lubricant or moving the ring as discussed. I have nearly new Dunlop Sport Maxx non run flats so assume they are okay, the wheels are 108’s but they have been refurbed probably fairly recently and I cannot remember seeing any balance weights on them so will get them balanced, I will also check tyre pressures again they were 25 psi all round when I first got the car! I think I put in 34 front 36 rear so I may drop them slightly. The spigot I think it’s called this? The part the wheel sits on looks very rusty on all corners so I will wire brush this down but not sure what I should apply afterwards. The front lollipop bushes were replaced last year so I wonder if they were done correctly? I will get my friendly one man mechanic who does my MOT check all the the other bushes front and rear and grease any parts that can be. I have also noticed a slight sound like brake rubbing which he thought would be the rear brake disc guards, not bad but annoying. I have also seen springs can break? I guess once everything is ruled out I can get a laser alignment done. Never had this with my old 2.8 Z3 it just sat planted on the road! Any thoughts greatly appreciated. Thanks

I've had a problem with what I would call 'twitchy' steering since I bought my car five years ago; at anything over 70 it was definitely a case of both hands on the wheel at all times!

I read this post when it first went out and have followed it on and off ever since and really thought I must give it a go. I think what stopped me was the same reason the car is still on run flats and that is I just don't drive it enough which is a poor reflection on me. Anyway this morning I finally got my backside in gear and got the job done and, thanks to all those who have gone before and shared their experiences, it was very straightforward and the result is nothing short of transformational.

I moved the ring anti-clockwise between 5-6mm which has had the effect of tightening the steering. All the twitching has gone and I can't detect any stickiness although the steering through the wheel is noticeably heavier (but in a reassuring way if that makes sense). Like others on here I will see how it goes and further adjust if necessary. If I do need to make any adjustments I would anticipate they would be in a clockwise direction 1mm at a time which would loosen the steering from it's current position.

For anyone procrastinating like me just do it, you'll only wish you'd done it sooner. :D

Further to my post yesterday I have a query which may also benefit others in future as well as myself should I need to make any more adjustments.

When you remove the footwell cover to access the steering column you have to disconnect three wires; one from the courtesy light and two from ' whatever it is', I'm not sure!!

Not wanting to have to put everything back until I'd tested the adjustment by driving the car, I carefully removed the two components from the cover and reattached the the three wires prior to turning on the ignition. Having read so many stories of dashboard warning lights and error codes I didn't want to trigger anything.

Is it necessary to reconnect the wires in this scenario or is it OK to leave them 'hanging' as it were?

Many thanks in advance :D

BostonJohn Your approach sounds good and logical. Checking tyres and suspension components before a thorough wheel alignment is a good starting point. If your steering is becoming sticky with rising ambient temperatures, that would certainly indicate that sticky steering is adding to/responsible for your woes. Drilling and lubricating the column is not advised.

Bluebogartlabel It sounds like it's going well for you! There's no need to keep the wires connected to the footwell bulb and the speaker (that's what emits your warning beeps for "lights on with door open" etc).

Thanks Wonkydonkey, I will,if all goes to plan get my car back from the bodyshop tomorrow, with a matching front bumper! So I can start investigating the steering. I had thought pumping grease into the steering column might be counter productive.
I will keep everyone posted as to how I get on as hopefully it will help others on the forum.

Just found this thread and i think it might be the answer to my problems!

The car has just had all its suspension done along with various bushes etc followed by a 4WA. When i drove it to the garage it was definitely difficult to keep in a straight line so i just thought the 4WA would sort this but alas it hasnt so Im guessing i need to tighten the slipring as mentioned.
But, on top of the wandering about on the dual carriage way, the steering wheel definitely seemed to kick to one side every now and again. It didnt feel like it was coming through the road and i did wonder if the power steering was at fault. Is this also a symptom of slack steering ring or do i have another problem i need to investigate?

Ratcatcher I would just get in there and see what improvements you can make by adjusting the ring on the column. I always recommend that people make these adjustments with the front wheels off the ground, though I'm not sure many people follow that advice, instead opting for numerous "finger in the air" adjustments and multiple road tests afterwards. If you follow my recommendation, it will allow you to feel what level of slop (or tightness) you have in your steering system before you make any adjustments. You will then be able to feel what effect your adjustments have before you go out for the test drive.

Agreed. Just been on the dual carriage way and when i touched the ton, the car became a bit scary tbh.
