Not sure what ULF is but it's a round toggle with 0 and 1 on it I believe.

that toggle switch does not sound as something OE BMW - you got a picture of it?

Ejector seat button. Don't press unless the ex wife is the passenger. Completely stock.
The coins though were an option.

interesting... that toggle switch does not look factory...

that entire compartment is pressure fitted and can be pulled out by just pulling it up - there might a piece of Velcro holding it but no tabs, screws - so, if you pull it out, where that toggle will lead you?

I bet it is something aftermarket - i just wonder, what it could be...

Time to take it apart and find out. Will let u know!

REST is designed to heat the car for 20 mins without key. Nice if you run an errrand and leave the gf in the car.
Pressing the DSC has it's own threads. level one, it flashes and turns off TC. level two, hold 30 secs and it turns off TC and shuts down the stability system controls.
most of thus stuff is in the manual, btw. they are only 'hidden' because you aint read it.
the radio button is not, cool feature. the stutter throttle downshift is not as well.
Happy Holidays Everyone!

This is a stock insert. There are three console insert options, Cassette holder, CD holder and deep (yours). I put this in, as well.

The switch is an aftermarket addition.:popcorn:

That switch could be for anything. With as fast as these things are, I wonder if it is hidden so well because in is for something like a rear light, brake light cut out switch. Highly illegal.

Disagree. Pressing the button once turns off DSC. It still leaves traction control on, but it increases the threshold before it intervenes. Pressing the button and holding it does nothing. It did on other versions of x-drive, including the one we had on our 325xi, and that is where the long-standing rumour comes from that it actually does anything on the E53. It doesn't.
