It's just switching off the key-lock window roll down feature. Even if they were fixing the security issue properly it has nothing to do with the OBDII port which is a standard interface on all cars. It's the BMW CAS security modules that have the key-adding security vulnerability, and these devices are on the CAN bus, with everything else, connnected to the OBD port. Just think though - lots of new cars now have wifi hotspots, so this means they are vulnerable to remote hacking for the first time. Next thing people will be having keys added, their address book and browsing history and passwords / credit card details nicked from their cars systems and phone connections without even being aware of it! |

Are BMW right in saying that a full software update is not required? I could do with some updates!

So if you updated your PC recently, then a new update today will only be a small one just for the new item. However, if you haven't updated your PC for months, then there will be a shed load of things need updating in one go. It's the same with BMW, they only have one 'update vehicle' dialogue button on their system and this will update all modules to the latest version, so the size / length of the update depends on your current car status and when it was last updated. If you car is recently up to date, then this new security update will only be a small update, if however like me your car has not been updated for years, then its a fair chance the EVERYTHING will need updating. The overall update status of your car is called the 'integration level'. for example in simplified terms: Integration level 1 = all modules at version 1 Integration level 2 = all modules at v1, but CAS at v2 Integration level 3 = all modules at v1, but CAS at v2 and DME at v2 etc etc. this goes on for years and years and the IL numbers are a long string of numbers and letters, but it's this 'integration level' that is looked at, not the individual module updates. Obviously a lot of module updates are interlinked, so they have to be done at the same time, so it's not up to the operator to choose which ones are done, he just presses 'go' and the system updates everything to the latest integration level. This is why they never know how long it will take to update the car as until they get it plugged in they don't know the current status, could be a 10 minute job or 5 hours.

Ok great, thanks for your help! This is what i thought but BMW were saying the opposite... probably trying to rip me off to pay for a full software update. Well that's good news then, something free out of BMW!

Yes, by simply smashing the window and accessing the OBD port in exactly the same way as before!

Apparently this fix disables the OBD port whilst the car does not have the appropriate key in the ignition, so it is no longer live at all times.

Took the car in to local dealer to have the supposed security fix and guess what - they couldn't do it! The new software is faulty (or at least their version of it)!
I mentioned the possibility of losing my 'mirrors-fold-with-fob' facility after the fix is carried out and was told they're happy to re-code free of charge if this happens. |

Mine went in for an engine light fault this morning and when I got the call to mention the car was ready, they told me they've also installed the 'software fix' even though I didn't request this, so kudos to BMW Heathrow.
Not sure if the fix resolves the issue, so my OBD is still hidden - I had to explain to the SA where I relocated it, they were absolutely fine with this. |

Can you kindly verify if your windows drop from remote after this 'update'? Thanks.

There is a way around it. Advance coding/ updating, where you can only update what you want to. However there may be compatibility issues of updated module as it requires some other modules to be updated simultaneously. (as you posted above). Experienced programmer / coder will know what modules should be updated if you update one. But as far as BMW updates is concerned, it works as you explained.
