Unhappy letter from BMW

hallo guys, just got a letter in the mail from BMW where it is explained how the brake system works, telling that if you overuse the brakes with a battery not 100% charged you will end up in a zone where it is uncertain the correct functionment of the system.
the translation of the pages of the info booklet are all but clear.
the booklet states at the end that we should not worry that all will be fine and "within specs"....the latins were saying "excusatio non petita recusatio manifesta" or if noone asks for a explanation it should be something unclear, there is something wrong.

did anyone get the same?

I believe that the electrical servo in draining too much power and at a certain point the battery will not deliver enough energy to get the system running. bmw did not comment on this.
my "S" is still waiting for the software upgrade, till next week i will be in san Francisco where the wheather is absolutely great and i wish I could ride on the wonderful coast.....

enjoy the new site it's great to have all of us back together.
Thanks

Question ABS and ERC

I took the ERC rider course on my '02 RS and there was no battery drain during the braking excercise. Wonder if its the same ABS system on our S as I am planning to take the ERC again next year. There is a lot of waiting around, short runs and hard braking in this course. Anyone take the ERC on their S yet?

I got the same letter, although it was for an R1100RT I don't own any longer. It sounded as if BMW is covering their butt on ABS, since the RT didn't have servos.

ABS or Not to ABS...

I just spoke to two dealers about ordering my new S... WITHOUT the ABS option...

Guess I don't have to worry about this prob?? Cool.

Can you do that or is that a "special order"?

I thought the warning had more to do with the servo than it did the ABS. In other words, if you pulled the crap out out of it repeatedly, like a kajillion times a minute for 5 minutes, during a "low battery" situation, than there wouldn't be enough power to operate junk. Non-ABS bikes still have a servo don't they? If so, I'm guessing the warning applies to them too.

Jerry, why are you going the non-ABS route?

If I recall correctly, this is in response to one of the testers in Germany crashing a K1200S after performing 25 full-on stops in a row. On the 26th attempt, the servo assist was not available and the rider may not have been prepared to use only residual braking an crashed.

I also got the letter and understood that the problem is merely the servo than ABS itself.
Having read that I remember wondering why my headlights are dimming so much due to voltage loss every time when I break. If the servo really takes that much power, now I understand why my headlights are doing that.
