New battery and software update.
Does the software become corrupt or is there and updated version ?

I was hoping to get a good answer to this but all I was told was something like the software shows the ebrake as a simple open or closed circuit and the low battery interferes with this. The software update fixes it.
Still doesnt make sense to me.

Sounds to me like “Yes sir, that’s a definite maybe“!
A simple “I dont know” would impress me more I’m afraid - I had enough BS in my working life to last me till I knock my elbows on the side of my casket!

It sounds though that this could happen to any E model as they will all have the same software in the car from the factory.
Although it would have been wise for BMW to make sure the updated software was in newer cars as soon as they knew there was a problem.

It would be nice to think the updated software was added to cars in for servicing, doesn’t look like it while they can get away with charging extra when the issue arises-poor show from Bmw :thumbsdown:

Happened to me this week.

Going to a dealer for an update. This thread today helped as they started with

"We need a comprehensive check on the whole car before we can say what it can be" £££££ talked them through what I know and this thread they have agreed to update for cheap next week.

So with all the ebrake problems being fixed by software updates, has anyone gone to trading standards for advice.
The brake system especially as the ebrake is also the emergency brake is a safety critical item, no different to faulty steering or air bags by design.
If software could wear out i can understand it requiring cash to fix, but safety critical should be subject to call back or at least a free fix when that problem arises. By paying we/you are admitting that it's not BMW's fault by design.
Look at all the VW that have been returned due to some dodgy software.

Funny that one of my customers last year was telling me how he got the push from VW Germany over that scandal, he now works for JLR!

I see you have a 2010 model, mine 2009 23i.
In 2013 six months after purchase my car was called back for software security update, foc.
Touch wood never had problems with ebrake.
Did many others out there get that call back.

Funnily enough we bought ours in August 2013. I wonder if the previous owner had a call and either didnt bother getting it done or had already sold it.

I’m wondering if the ebrake software was changed along the production run by bmw, what’s the age of the newest e89 that’s had this issue?

I forgot to post back here- mine had this last year, and again, a full charge and a software update fixed it.
Interestingly, they updated the software on all the modules so it also fixed an annoying distortion when playing from a USB stick in the armrest (I don't have the screen and stuff) so that was a nice change.
However, I've recently been having a warning bong with the car on ramp symbol (started another thread) but no other warnings, and occasionally still see low battery... so something not quite right still.

I'm interested in a local E89 3.0i (2009 - private sale) and took it for a test drive a few weeks ago. When the owner first fired it up he said 'oh, haven't seen that before' and it was the e-brake warning. The brake still seemed to work ok despite the warning symbol. He said he would take it to the local garage and get it fixed before selling it, but I wonder if it needed more than that (ie, the software update)? I haven't been in contact with him since, but might follow up on it to see what the fault was.

Would be interesting to see if anyone has had the same problem after the update? My assumption is the update lets the e-brake "tolerate" a low battery situation without going wrong but I guess I'll know for sure if mine does it again...

I am having this same issue today.. :-(
I had this issue before and the dealer updated the software already and everything seems fine during summer time.

I didn't drive my Z4 for 3 weeks now and today I took it out for a car wash. While I was waiting in the line, I shut off the car and the battery warning sign came up so I was like.."I know I know...I didn't drive it for 3 weeks already!"
But after car wash, the Parking/ebrake warning sign (Yellow P) came up and my ebrake is stuck.........
My car was stuck in the wash bay for 15 min and then I gave up. Locked the car and walked outside to call for help.
When I came back after 10 min, I started the car one more time, and the warning yellow P was still on but at least the brake is now released.

I don't even know if I should bring it back to dealer because they will not be able to replicate the problem :thumbsdown:

Assuming you bought it from them, I'd take it back - the fault code should be stored on the On Board Diagnostics.
