My Ride: 2002 545i sport pckg,sirius,active steering,grey on black
Talking

Had a chance to unwind on I-68 in western Maryland[a great 4 lane highway

where you can maintain very high speeds for long periods..many sweepers

through the mountains and great views too]. The problem was crosswinds that

required frequent annoying steering inputs resulting in a twitchy feel. BMW

apparently feels that this is such a problem that Autoweek says they deleted

Active Steering from the new M5! Any ideas or suggestions? Can I retroactively

disable AS? My previous 540i[Sports] had a much steadier feel while in warp

drive.

Yeah, they should make it an option to turn of AS. I'm sure alot of ppl would like that option.

Maybe they could make the AS with adjustable ratio in the iDrive.

I agree, more of an active steering issue. I have driven my car across the Causeway, a 24 mile bridge over our lake, with 25+ mph cross winds, and felt very little impact. I have heard other with similar comments about cars w/ AS in strong winds.

It makes sense. The AS magnifies each movement of the steering wheel, whether it be by the driver or in reaction to wheel movement in high winds.

What it seems like is happening is AS is making corrections for the crosswinds, then I react to the corrections, so in effect, it's back to the old ways of corrective steering input in winds, which I think AS was supposed to help with. Seems like human nature's gotten the best of us.

I vote for an AS off button, too. Would be good for valets, etc who drive the car and aren't used to it.

I thought AS worked differently than described above.

at low speeds, a little input results in large movements. at high speeds, a larger input results in smaller movements, exactly for stability at high speeds. what gives? I just read the e60 brochure, and that's how I understood it.

please explain.

I read it's still 11% active at high speed. Maybe that's too much. Or there's another problem.
