Brake light warning question

Hi all!

I recently bought an '08 535ix (my first BMW).

Today, after a lot of snow (not sure if that has anything to do with this) I got in my car and had a yellow "brake" warning light on my dash.

Naturally, I engaged the hand brake to see if that was it. It turned red when I engaged the hand brake and then went back to yellow when I released it.

All the owner's manual says about this "BRAKE" light on the dash is:

Indicator lamp
The indicator lamp lights up, and a signal
also sounds when starting off. The
handbrake is applied.


So............ what am I missing?

Not that automatically showed up. Keep in mind, I'm new to this and only have my owner's manual for reference.

So I went in the vehicle info in iDrive. It shows all green "OK's" for everything. Rear and front pads are +15,000 miles until replacement.

I went into break fluid and it shows 12/2013.

I just went out and started my car again. The light no longer stays on.

It was in a parking lot today, but is now in an un-heated garage.... but the snow might have melted from the heat of the vehicle once it wasn't exposed to the snow anymore.

At any rate, is this something I need to worry about in the future? Common with heavy snow and a parked car?

Thanks in advance for any light shed on this subject, for a newbie

Alright, so my problem is back again.

Now I am getting the service logo (car up on the jack) and the iDrive system is telling me that there is a break-pad wear sensor error.

Is this a big deal?

Is it simple to change myself?

Youtube is your best friend.
Although the vids are not for the E60's all BMW uses single piston floating calipers (Except a couple ones) so they should be pretty much the same procedure.
There are a couple vids for the front brake pads but they are mostly for the E39, E46 etc but you can still adapt the procedures for the E60.

Rear brake pads

Most likely(I can be wrong) you have worn brake pads.
in heavy snow your DTC/DSC/ABS system brakes more often to control spinning wheel due to poor traction, thus promote more wear on the pads.

I'd check all brake pads to be sure.
If you have worn pads, which allows the sensor to be shaved by rotor then changing the sensor alone is futile, you need to replace pads as well as rotors.

Have you check the Brake fluid resevoir? May be as simple as low brake fluid.
