And there are EU regulations in force to stop them doing just that. If ways around that encryption are then supplied to said indies then obviously that will get out and we're back to square one.
Rich, with method 'a' suggested, OBD port will be disabled only when the car is locked. It will not affect the funtionality of the car and I cannot imagine if any indy will work on a car after locking it. So it is as simple as it is.

With mthod 'b', they need to secure the level of key's algorithm only and nothing else. But I can see that it will fail as it failed now. When e9x security system was designed, it was secure but now there are ways around it. If BMW improves the security of key's data (more specifically pulling out the information from specific module), people will find ways to crack that one as well.

Well I have tested both sides of UK specs cars (more than 1) and it is no surprise to me that NSF area is as incompetent as OSF.

I just hope that this update is not just the tweaking of sensors settings but hopefully more than that.
