Z4 Steering Kinks - BMW Forum

STIHLBOLTS · 06-13-2009, 06:57 PM

Has anyone else noticed a slight kink in the steering when going down the highway? It's like a catch just as I start to turn the wheel. I asked my dealer shop about it and I was told the wheel power was electric.

No such thing on my car. Happily for me, the steering is always smooth at all speeds.

Since we don't have the same car's are you just trying to be a funny man?

Do you hear any sounds when this "kink" happens? Perhaps a knocking sound? Or do you just feel play in the suspension?

STIHLBOLTS · 07-09-2009, 09:02 AM

No sounds, just a stop and then I push harder and it goes over. It just gives me the feeling that if I push too hard I am going to over steer and instead of moving over a lane I am going to go into the median. It felt like if in a hydraulic system there might be air in the line, but since it's electric that can't be the problem.

Hmmm...that's really odd.

STIHLBOLTS · 07-09-2009, 03:50 PM

Of course it's odd.

I just wish it were not there.

Yeah, I hear you on that. I'm currently fighting back gremlins on my car with a broom stick. Read this thread at Roadfly. It seems they talked a lot about the same things you've been experiencing.

"Locked on center feel"

That is so close to what I am getting, but I have not noticed anything to do with temp. Thanks, now at least I know I'm not completely nuts.

I will have to do some experiments with out the wife in the car with the turn thing there, as far as I can tell I have not noticed that issue. But who knows that may be there too and its just part of the car's make up. I still have thread left on my Run Flats and once they are used up I am switching to Michelin PS2's. The whole flat wheel may be a issue too. (not as in flat tire).

All I can sumize is that other's have had this issue and no one has solved it. Thanks for your imput!

Yeah, I'm not too sure that temp would have a whole lot to do with the problem...but stranger things have happened

Run flats are horrific and I'd rather get a flat and have to get a tow or patch on the side of the road rather than have run flats on my car.

You're welcome. The problem with mass produced cars is that if you have a problem, guarantee someone else has the same problem. I hope you get it figured out.

Do a google search on "Z4 sticky steering"...you will find out more than you ever wanted to know about this! It strikes 2003 and 2004 Z4s. File a complaint with NHTSA, this needs to be a recall!
