Just wondering as well, the servo in this link, would it be worth changing this unit to see if it helped the issue? As part of a smaller, less expensive gamble to sort it? Still trying to establish a list of smaller, less expensive avenues to explore before anybody has to resign themselves to buying the dearer full columns.

Should maybe call them before buying and clarifying as they say:
Item description:
Spares or repairs as it looks like faulty part.
Part number: 6763764, 0273010010.

Yes exactly as we are using an m8 threaded nipple. Just discount that section and follow my guid for that bit.

Might be worth blathering the drills in grease before they actually break through and also the tap to pick up any swarf as you don't want that inside. Have used this method when heli coiling spark plug holes on bikes without removing the cyl head.
 
Completely agree give these people a ring first.

The tap I supplied is actually a machine tap. The work perfectly well by hand. But it's got a helix so should bring most of the swarf out the flutes.

But there is a risk some will make its way inside!!

Just to be Lear I accept no responsibility. I have just provided some tools and some very limited knowledge!!
 
This is handy if you want to indulge in full-house E85 steering geekyness, kind of supports the theories about the system, fault codes, voltages etc, and sticky steering being an inherent fail-safe response to system overheating.

Sometimes seen on forum hoons :D

It gets your attention, and of course is the reason you have a fog light that appears not to work... As I found out early on after spending at least an hour removing the rear lights and swapping bulbs around :headbang:

Hijack over :D
 
ooooffffttttt " Magnetoresistance" what the,,,sounds like a character out of X men anyways done a bit of reaserch http://www.murata.com/products/sensor/principle/effect.html , even a calculation how to fix sticky steering :rofl:
 
A little history here.

I have a 04 Z4 3.0i, sticky steering issue was brought up to dealer while it was in warranty. checked out and said nothing was wrong. Again issue was brought up to dealer. This time they said they made some adjustments (what adjustments I don't know???). Problem continued and warranty finally went out. Called dealer and told them I was bringing the car back because there definately was a problem. No questions asked, they said a new column would be on order and would notify me when it comes in. Job done and issue resolved. Since I had it documented while in warranty, they did not charge me at all.

It doesn't matter what approach you take with correcting the steering, the issue here is that BMW is very much aware of the problem/defect and will not voluntarily arrange to have it fixed/replaced. Calling the BMW hotline may worth a try to see if they will do anything at all, never know what results you might get.

So just my thoughts, seems you all have a good handle on it.

These people might be worth a phone call.........http://www.bba-reman.com/content.aspx?content=BMW-Z4-EPS



Spoke to a Gary @ this company today .......unable to quote a repair cost or even confirm a repair is possable , offered to test own unit and report of a repair is viable but up to now all E85 EPS units sent in have been returned to customers in original faulty condition without charge .

Thats my one on ebay....if you need any more photos, give me a shout

PS if anyone on here it thinking about clicking the buy it now, please dont, as I would take £50 for it off a forum member :thumbsup:
 
Is there a number for a department in BMW that may be worth calling? I think I would like to have a chat with someone about this issue personally. It may not bring about any sort of result, but think I would like to give it a go.

Cheers for phoning that company Slick :thumbsup: pity they weren't able to offer more insight.

The kit from machine monkey arrived with me today, so all I need to do is source the grease gun and the courage to take a drill to the car. I could like with the sticky steering rather than buy a new steering column for now, however if I do this wrong I might bring about a self inflicted new steering column :lol: Any tips before I give it a go guys?
 
No point in contacting BMW about this, more so as there was a BMW case opened for this and the outcome was 'no recall' which gives little or no hope in BMW dealers fixing the issue if it pops up on your car

As everything else, there is already a long and detailed thread on the forum about this topic

I think this will take you to the actual report and related documents

Thanks Ranski, helpful stuff :thumbsup: BMW clearly acknowledge that there is an issue, but also clearly play down its impact.

On another note, does anyone know how easy or difficult it is to change the lower part of the steering column that JaxZ4 had success with? Seen in the link below. Could it be a DIY job?

I guess the potential lawsuit's for crashes caused by this defect were outweighed by the cost of a mass recall

I would say you're spot on. The recall would obviously have been a massively costly action, simply wouldn't make financial sense given the insignificant impact this issue has on BMW and the Z4 market as a whole.

Fairly painless to change that part from what I remember.
 
That sounds good Stoat, fairly painless jobs are the ones we all like! Do you remember the rough process? Where is it best accessed from? The key thing is always whether a job can be done without any ridiculous special BMW tools etc!
