Event Data Recorder

I was reading through the manual and it mentions an Event Data Recorder, does anyone know what data it records and if we can disable it?

I would imagine top speed, max rpm, mpg, avg speed, etc. My friend's mom took her Z4 in for service and they asked here when she had gotten to 135...my friend was racing an RX-8 in it one day.

umm only 135 I imagine it was fun explaining that one. On a serious note If you blew your engine this can be used as incriminating evidence of possible driver error. For enthusiastic drivers like us this may not be a good thing.

Exactly...or the opposite...my friend's E46 M3 suffered from the infamous catastrophic engine failure...at first they implied that it was his fault...when they pulled the computer it showed evidence of normal use...replaced his engine with no questions after that...

The worst part is the cops can use that data to nail you if you were at fault during an accident.

I read in an article somewhere that cops were able to wireless download the EDR data at traffic stops. Scary if true and prob not more than a few years away when the insurance companies buy download tools for the police.

That doesn't sound the least bit legal and how could they prosecute you without seeing it happen?

Yeah it's not legal in that since. If I'm not mistaken I think in 2010 or 2011 the car makers will be mandated to have them in all cars or to at least fully disclose that the car has a EDR. There's been quite a debate over the whole thing raising privacy concerns, etc. You can only imagine once the auto insurance companies get ahold of this information

I think the logic was that this information will provide first responders with timely and accurate information that will save lives in the future. If you ask me it's just big brother watching.

I don't see how this can ever become legal. They might as well strap a camera on my head and record everything I do every day just in case I do something bad. I doubt that it will fly. Even if it does, what is to keep me from disabling it? On what grounds could they prosecute me for disabling such a device? It would only create a new market for people selling code to disable such garbage.

Which brings us back to the point the OP was making. How do we disable data logging in the ECU?

I remember reading an article regarding this subject about a year ago. In fact BMW was one of the few auto companies that said they were not going to install recording devices in their cars. GM is one of the worst offenders because the parameters recorded were (going from memory here) many and the GM cars recorded all perameters like 30 seconds before a crash.

I suspect that BMWs only record perameters but don't put a time stamp on them so that the data is useless to law enforcement officials. Also, I heard the data is recorded onto a memory chip in the key, therefore if you get in an accident where you were doing something illegal (like speeding), be sure to take the key with you afterward, because it has the evidence recorded on it. Replacing your "lost" key, might be cheaper than lawyer fees and fines if you were doing something "dumb" when the accident happened.

We need some research on this subject. I'd love to know more.

From my understanding the EDR is well integrated into the car's systems so I'm not sure if it's as easy as disconnecting a plug or two if you will. I know my previous BMW 2006 E60 had one as well. I can't recall where I have seen it but I thought they just record the last few secs not 30 but it may vary from company to company.

I agree with you Lucid, might as well strap a camera on me! Brave new world we're entering in my friend.

There are different systems out there. I think some of the Detroit cars have one that continuously overwrites the information so only a short period before an event, like an accident, is recorded. On the E46 M3 the system recorded max revs and time above certain revs, etc., but it was not timestamped at all--no way to prove whether an overrev didn't happen when in the dealer's care.

I believe so. A fellow forum members 2011 E92 had engine problems and the dealer mentioned to him, that he had gone about a certain speed. Not that the speed mattered. Which would there had to some sort of EDC.

Interesting. So dealers can access this information. What about law enforcement? I have seen some cases where the insurance adjuster or the police officer seek to obtain this information following a crash. Does anyone know if BMW is like GM in this regard?

It is not easy to obtain the crash data from an EDR on a BMW car. A dealer can get some data from the car but to extract crash data from the EDR the ECM has to be removed from the vehicle and sent to Germany where the data is extracted and deciphered by BMW AG. BMW is not like one of the "Big Three" where the data is able to be extracted by almost anyone with the proper scan tool to read crash data. BMW considers the crash data to be the property of the vehicle owner and refuses to release it unless they have signed consent from the owner of the car.

I went through this with my insurance company in 2009 with when my 09 M3 was written off. The insurance company tried to have the crash data pulled from the EDR but their independent guy that normally reads the data off of vehicles for them, as well as the local dealer could not get the information off of the car. Once they realized the process required to obtain the data from the EDR and the fact I would have to sign a release to allow BMW to disclose the data, they just gave up and paid the claim since their time was up to settle.
