Replaced Battery Now No E-brake No Cruise Control etc

[Valor1]

I replaced my battery after the car would not start. With the new battery car starts fine but the E-brake does not work. Also the cruise control does not work and I get a TPMS not functioning warning on the dash as well.

I've read where this maybe a software glitch that arises after the low voltage condition?

Has anyone else experienced this?
What's the fix?

First - have you coded the battery to the car?

Second, the e-brake can fail if your battery goes low, it happened to mine and it is a software update required.

Mine was done at BMW but I am sure a decent indie could sort it out

Not certain abut CC or TPMS

My understanding is battery coding relates to recharging of the battery and does not impact other systems?

Why would the e-brake, an important safety item, fail if a battery goes low?

Do you know what kind of software update is required? The local dealer, BMW of Beverly Hills, gives me a blank look when I mention that I think it is a software update.

just noted that you are in the states, not certain if the e-brake issue affect cars stateside, however, this is a well know and discussed point on here - just do a search as you are not exactly the first one to ask about safety and brakes but it was 100% a software issue on mine, it failed when I went to collect the car and it took 4 or 5 weeks to get it sorted due to the pandemic.

Mine also showed wheel speed sensor failure

Not certain what the coding of the battery relates too, just know it needs to be coded.

Just one thread on it, there are several if you search

The e brake cpu wakes up periodically/ is woken up when certain events happen..

With a flat battery early versions would brick themselves on power up..

Software update removed this bug..

Think this post sums it up -

Well I've done a diagnostics scan on the car and I get error code 6017 which is the wheel speed sensor DFA_EMF in the parking brake module.

Turns out that a drop in voltage I.e. Your battery charge is low can throw this up. So if you've a new car and leave it parked up for 3 weeks you might get the same issue.

Basically the only way to cure this is to complete a full softwear update to the vehicle including CAS per diag code D3440_EMF0000T_90_200. After programing fault codes should be cleared and road tested performed.

So I suspect that's what happened to be OP in this one. It's a joke really that it can throw an error that can only be resolved via a softwear update. Now to get it booked in.

THANK YOU EVERYONE! Sounds like the issue I am having. Now after reading that thread I don't understand why BMW would charge us to fix their software glitch? My dealer wants to charge me over $200 to diagnose plus $$$ to fix the problem even after I just explained all of this information to the Tech. I am now reaching out to the service manager.

As others have noted, this is a safety issue and a low battery should not cause your emergency brake to fail.

Page 52 of the owners manual says this is can be used as an emergency brake, so why would BMW not fix this safety defect without charging its customers?

So they can screw more money from their trusting customers that why, you’re lucky over there as bmw replaced your cracked 19” wheels & hpfp’s - over here they just laughed at us

The issues is that if it is something else then you could be paying twice anyway so the diagnostic check should point to the correct repair but $200 seems a lot based on uk pricing of around £60 to £80 (which we also begrudge paying), remember we are only advising what we think is the cause based on your comments - we cant see the car.

You mentioned the local stealer was puzzled by your initial software update, not certain I would be going to them after this (although when I bought mine from a non franchised dealer they changed the wheel speed sensor first - then I told them what the issue was based on the threads in here) - they will be charging $300 for the update as well I imagine which is a real con as plug in laptop, start update and work on another car while just checking on yours occasionally, they certainly don't sit three for 3 hours.

Is there another local BMW garage or a good independent you can go to - maybe even call to see if they have any ideas on the issue.

Wow that's terrible. For the record, they did not replace my wheels....for reasons beyond me. Does Porsche treat their customers like this?

So I insisted the dealer do the "recall" software update which was for emissions purposes. I had to nearly argue with the service advisor to have that update done first before spending over $200 on a diagnostic run: A service advisor who frankly seemed to know very little about cars and care for the customer even less!

Well, seems the emissions update is really a full DME update and viola, E-Brake is working again!

Now I have two other issues:

1. How to delete music files from the harddrive.....and BMW of Beverly Hills could not figure it out!

2. How to get oil level readout as system says "oil level measure is inactive due to sensor error."

 

[Chippie]

The engine has to be up to normal operating temperature and the car on a level surface to check the oil level, if it still won’t read the oil level then you may have a faulty oil level sensor

 

[flybobbie]

I have said about this for ages, software stopping the ebrake working should be a recall item, no different to a faulty air bag.
Ebrake is a safety critical item, if BMW have messed up they need to fix it.

Never had problem with ebrake but shortly after i bought my car a 2009 23i it was called back in 2013 for a security software update.
I wonder if that over the years stopped any problem with ebrake.

My colleagues car a 2012 at 12k miles the ebrake failed, last straw of various failures she got rid of car.

How to delete music from hard drive

Thank you. I was on pretty level ground and had driven the car about ten miles.....but I will try again. I've also read where low voltage from a battery can cause this error as well.

Why would BMW engineer a car where something as simple as low voltage could cause all these system failures......

How to delete music from hard drive

Thank you. That's the first thing I did....refer to the manual.

But the options shown in the manual are not appearing on my screen. That's the oddpart. Otherwise radio/nav works fine.

Yesterday BMW service said they could not delete the files either. Then the service advisor, Parametch Sanhaphakd, tells me the tech used some tool to delete the files from the HD. Then I take the car home and find they are still there!

This is the same service Advisor who wanted me to pay for a diagnostics before doing the recall DME upgrade which, as I thought it might, fixed the E Brake not working problem.

The same Service Advisor who, at 5:00 p.m. yesterday, when I asked what it would cost to replace the three panels on my dash that all have bubbling leather (on a car that literally just turned 18k miles and is always garaged and when outside always has sunshades covering the dash), said it was too late to give me a quote (the closed at 6 or an hour later) but estimated labor alone was 18 hours at a rate of ~$200 per hour.

You are 100 percent correct. Owners manual states this brake also serves as an emergency brake so how/why BMW skirts taking responsibility for a critical safety item is really indicative of the corporate mindset at BMW....which is very disheartening.

I suspect every person who paid BMW to "update" their software to fix this problem had a car that needed the "recall" update and as such, should not have been charged at all.

BMW should have done a recall on this as, for them, it is an inexpensive fix of a defective design component.

Sounds like your friend who got rid of her Z4 had similar experiences with me at her BMW dealer. Really foolish as the MSRP on my car was just under $65k and the idea of buying another BMW product at this point encounters the existing bad taste in my mouth given these experiences.

Can you access other functions from the hard drive, like hard drive free capacity or backing up music collection?
