is this a bug??
 

hi all,

something weard happened today while i was parked and talking on my phone through bluetooth as usual i switch off the car took the key out and still talked on the phone. suddently i pressed the start by mistake while my foot on the brake without the key in and the car started normaly...:rolleyes: Is this a bug? I dont have comfort access...

thanks,

The CAS control module ignores the rolling code signal from the key within 10 seconds of removal, this is to allow the driver to start the engine if the key were to fall out, or if the vehicle were to stall. This has been a feature since 1997 i think.

this is a feature. as long as you do not open the driver's side door, you have 'comfort access' :D

How would this have been possible in 1997? Wasn't the 2006 3 Series (E90) the first BMW to have a start/stop button (excluding the very limited production Z8 & Z8 Alpina)?

it was actually from 01/95 production.

The DME retains the ISN information from the EWS/CAS module for 10 seconds after the ignition is switched off. Restarting or switching the ignition on within the 10 seconds cancels the key identification process.

you are mis-under standing me. the key code is ignored when re-starting the engine. lets say you have a 1997 528i. you have 2 keys. the customer states that one key does not start the car. You start the car with the good key. you turn off the car, and then put the second key in with in 10 seconds, it start the car also. so you think the customer is crazy. But if you wait 10 seconds and then try to start the engine, it will not start. This is a safety precaution to allow you to restart the vehicle if the key transmitter were bad.

now with the key holder on the newer cars, lets say the key holders hall sensors failed, and cannot detect the position of the key to extend the claws so you push in the key, it falls out, and you hit the start stop button, and the car starts anyway, get what i mean?

I'm sure you're explaining it correctly and clearly as possible, but I still don't get it :dunno: My fault though!! ;)
