That's good to know! I would have no license without my V1. Thanks for the knowledge!!

Yes you are correct. Check out this cool link Jason posted for more info than you can ever want on the subject.

In no way was the S85 like a "locomotive engine" it was probably the one of the most advanced engines of its time. Also again in no was is the S63TÜ old school.

i agree, i felt it and you know its there. i almost thought something was wrong.
good to know it will eventually go away or i maybe my hands will be numb by then

There is no way they would allow any kind of high frequency vibration in a production car. Especially of this caliber. Clearly a tire or wheel imbalance. I mean come on. This just showed that this guy doesn't know anything about cars.

Also just wanted to note that I am not just some wanker fanboy. I like criticism but make it useful or knowledgeable. For christ sake he didn't even mention the fake engine noise that everyone is all excited about.

They allowed incorrectly sized rear coil springs in this car (resulting in a clunking rear suspension), so I wouldn't put steering vibration beyond the realm of possibility in this car...

You know this how? and the conclusion comes from where?

Keep in mind I question the statement not you or your knowledge. As in most internet conversations. You know nothing about me and my qualifications and neither do I about you. But from my background (Purdue, Mechanical Engineer. Owner in Aerospace Engineering company for 8 years) I do not buy a high frequency vibration resulting from a dynamic imbalance in the car due to bad coils.

But I have been wrong.

[visualguy]

I'm not saying the bad coils are causing steering vibration. My point is that BMW allowed the bad coils problem to happen on this car, so I wouldn't be exactly shocked if other problems are discovered, unfortunately...

It's more of a low frequency vibration, not high frequency. I sent my car for a round of tire balancing at the dealer, but it didn't help. It got better with mileage so i am guessing it's something to do with the contacts at the steering column loosening up over time.

There have been quite a few reports from owners of a high speed vibration thru' the steering wheel that either markedly reduces or goes away with a couple of thousand miles on the car. This does not imply a wheel balance issue from the factory. As for a major manufacturer not releasing a car with a high frequency vibration issue I beg to differ. Early production 2010 Audi S4s were prone to having incorrect bushings in the control arms that resulted in a wheel imbalance at 65mph. Those control arms had to be replaced which completely eliminated the imbalance issue. I know because my S4 was so afflicted.

I remember this. Interesting. Well time will tell.
