Known resolution for the "sticky brake" problem?

Notorious · 04-22-2008, 05:38 AM

Is there a known fix for the sticky brake problem in the E9x? In the past i've read that a Progman update would fix it, but there doesn't seem to be anything offical about that. Any insight?

Never heard of such. There was a "problem" w/comfort stop around the time of the initial launch, and I haven't even heard anything about that in almost 2 yrs.

Never heard of the problem or the fix?

I've seen numerous people complain about it on these forums, and for those that don't know, im reffering to the issue of the brakes not immediately releasing when your foot is lifted from the pedal from a stop, giving a "sticking" sensation before releasing and lurching forward. I've seen it most commonly reffered to as "sticky brakes" here on E90post.

I got PROGMAN ver. 27 a while back which helped alleviate the sticky brakes. Its not as bad as before, but it's still there. I don't know if its been completely fixed in the latest PROGMAN

this is a feature of the car - its called break assist

Great in theory, poor in practice. It should be called brake desist.

Streetfish · 04-22-2008, 02:50 PM

perhaps it should only engage when on a hill and only for MT cars.

f30er · 04-22-2008, 03:02 PM

I also used to have the problem. The dealer wouldn't even upgrade my Progman although it supposedly fixes the problem. About a month ago, I had my battery disconnected while taking out the airbag for the paddle shifter mod, and then a day or two later, I also reset my transmission. And now, it doesn't do it anymore! Just try disconnecting the battery for a little while, and then reset the transmission if it's an auto and see what happens.....

same way as you.
BMW reflashed ECU and problem went away, but not completely, there is hint of it once in while.

rrandyy · 04-22-2008, 03:48 PM

Yeah, the issue is still there...

Revlis · 04-22-2008, 04:03 PM

Yeah, Never heard of it... Brake assist does what it's supposed to do, sometimes it engages when I think I am pretty level otherwise it's mostly transparent.

It seems this issue is more prevalent in cars with an auto trans

Easiest way to describe it is say you're coming up on a red light and you start slowing down....right when you're going ~2-3 mph, the light turns green....so you take your foot off the brake, and onto the gas (not stomping on it, just normal light pressure)....this is where it gets weird, the car doesn't do anything at first, then, it sort of "jumps" forward.....feeling almost as if either the brake assist wasn't letting go of the brakes, or, the auto transmission downshifted into 1st for a split second before going back to normal......

It may even be a combination of both which would explain why resetting the tranny & ecu seem to make the problem go away(for now).

wow, i have been on this board for a LONG time and just now find this thread! I have been having the sticky break problem in my auto E92. like when I let up off the brake to move from a stop it takes a second or two for it to move and I always thought there was something wrong with the brakes and thats why its would stick....guess this is a common issue....

Hmm, i read in another thread many people saying the trans reset was a myth... I may give it a go, along with the battery disconnect. I also have the Auto.

Has anyone talked to thier dealership about this problem?

They couldn't replicate the problem and so there's nothing they could do...took a tech for a drive, he said i was giving it too much gas and that I needed to learn how to go easy on my car

ex-poster · 04-22-2008, 07:44 PM

Supposedly there's a TSB for this problem - but I haven't actually seen it.

I did bitch at my CA and SA enough that they put a good person on it, they "applied the TSB" and sure enough, the problem went away... temporarily.

Supposedly this has something to do with the torque converter, but I'm not sure what I believe anymore. All I can say is that it's negatively impacting my opinion of BMW every damn time I drive the car, and I'm not at all sure I want to buy another BMW at this point. I have been close to pulling the trigger on a 335i, but I can't until this gets permanently fixed, which I'm starting to doubt will ever happen.
