If you're ever down London way at the same time as me you're welcome to try my 108s with Eagle F1s.
An expensive month and I've still got the same steering issue, what next?

I did think about selling the Zed because this has been doing my head in for ages! I've now bought some Meyle HD wishbones and bushes which I'm going to have a go at fitting at the weekend
Hopefully that will resolve the issue. If not.... 
I did think about trying some different wheels but I don't know anyone that lives near me that has any spare wheels.

Thanks Steve
I don't often venture darn sarth in the Zed. Once it's running smoothly though I'm going to plan a few road trips! 
Or anyone else local, worth trying a new set of tyres so see how much of an effect they have. I think you could have a few small issues combining into a larger one. At your mileage I do think if you've got the money (i.e. won't be in debt) and are planning on keeping then wishbones, ARB bushes and drop links F&R, and RTABs are worth doing. You could do all of that for less than £300 which is still a saving on your original 'fix' quote. Try the RTABs first if you want to start small money first. Longer term think about your shocks too, my rears were shot and that doesn't help with the ride and handling.

I think you're right, I've come to the realisation that I will be better off changing all the mentioned bushes. I'll see what happens after I've fitted the new wishbones and bushings. RTABs will be after that and I'll try borrowing some wheels from someone.
I got the Meyle HD wishbone and bushes/lollipops pair for £181. My Indy wanted that for just one side, and that was just the wishbone without bushes/lollipops! Already saved a couple of hundred £££
In reality these are consumable parts, now I've done mine the car feels so much better and what I imagine it was like new.
DIY really keeps the costs down and means you can do so much more.
Be prepared to get held up though, you will need a splitter on the wishbones.

You'll notice the difference, front will feel much tighter.

Had the same problem with my 4th z4
Nothing fixed it
It was so unstable on the motorway it felt dangerous, always wanting to jump in to the adjacent lane unless I had a firm grip on the wheel .... Slow turning, high speed roads were a nightmare
I tried, new wishbones, new struts, new tyres and then sold it
Hope you find a fix as it was horrible to drive and I know how you feel

Isn't tramlining related to the car following the grooves in the road? Most often on the inside lane where lorries have been and most often related to runflat tyres?
I don't have runflat tyres and my car pulls (it's actually more like it's wandering) left to right on any road when I got above 50-60 MPH.
I still have the issue after having new wishbones and bushings fitted. It's not as bad as it was before fiting new wishbones. I'm going to fit some new ARB and RTAB bushes next but I've not had the money lately since the missus lost her job :|
To be honest it's kind of like my tinitus... after a while I got used to it and barely notice it now :lol:

No mate
I gave up pretty quick lol
I owned 2 coupes previous to that one and it just seemed dangerous so part exchanged it ( S700 GJB if anyone now owns it ), the dealer had done the repairs that took it in part ex and wouldn't even AUC it as they thought it was a shocker after driving it,
It's all a bit of a mystery but I've also seen other members post the same thing about 2006/2007 cars and never seen a explanation/resolution
It got to the point where if I were driving on the motorway I was nervous all the time and expecting it to veer violently to the right when just pottering about at 70, other z4s tramlined a little but nowt compared to this one
Keep us updated mate

Is this a different problem to the electric steering being affected by heat on the electric parts where assistance cuts in and out when making small corrections from the straight ahead?
steveyorks said:
I have a theory that this is a software issue where the firmware for some electronics is conflicting with others.
Don't have the problem on my car but have read a fair bit about it on here.
Would be interesting to compare the firmware versions from cars with and without the issue although they might all be the same.
When I had a 2.5 BMW changed the heating unit on the car and the Power Steering failed two days later. After looking at it they flashed the firmware back to the previous version and all was ok again and the problem didn't return.
This happened in March 2007 and they told me at the time the heating units had an upgraded version of the software.

From what I read it was down to heat effecting the parts of the steering and was prevalent in America where BMW rectified it under warranty. Given the massive heat generated by exhaust, engine etc its not surprising it can also occur elsewhere. I am no expert but did a bit of reading up when I felt it on mine. Having said that I lubed all the steering joints etc so I may have eradicated the issue by doing that in which case I didnt have the problem above at all!
