banky · 07-20-2011, 11:02 AM

hey guys, remember, still new with my first BMW so im not used to all these gadgets.. lol theres still buttons im trying to figure out.

so, when i unlock sometimes (i think its after a long shutdown) i hear a motorized sound.. and i cant figure out what it is. i have the setting for memory key off and im the only one who drives the car anyway using only one FOB.

what the hell is moving in my car during unlock?

thanks for any help.

it's the self destruct mode delaying itself, if you sit in the seat with one hand on your belly and the other patting your head the car completely blows itself up.

Pressure builds up inside the cabin when your car is parked. This is especially true when it's hot out. When you unlock the doors, the car will start to release all that built up pressure. Look under the wheel well of the driver side rear wheel. You can see a tube there that releases this pressure. You can also smell it.

O HELLA BMW · 07-20-2011, 03:08 PM

I thought it was the fuel pumps

banky · 07-20-2011, 05:09 PM

so now theres two possible answers?

banky · 07-20-2011, 06:06 PM

Whatever it is it only does it sometimes. After parking for 9 hours at work I unlocked it and no motorized noise but last night when going somewhere after being parked for a few hours it made the noise...

This is normal right?
