Alright, I'm on the way home and exiting the shopping center parking lot. The brake pedal goes all the way to the floor and the DSC light comes on, but the brakes still have some grab. I decide to turn around and take a look-see. I look underneath, nothin', check the master cylinder, full. I roll around the lot a bit testing the brakes and they're still going to the floor. I turn the car off and re-start a couple times with no change. I determine I can make it home and about 2 miles down the road the brakes are back to normal.

Thinking back, the car seemed sluggish drifting in nuetral(5 spd) and I actually checked the e-brake to ensure it wasn't engaged.
Anyone encountered this ?

power brakes? brake booster? this prolly should be in the e46 section, might get more help

did you pump the brakes at all? if you did was the car off or on when you pumped them?

The car was on, I was driving it. I could push the pedal all the way to the floor where it finally offer ed some resistance. This morning with the car off, I could push the pedal passed normal but not to the floor, and with a few pumps had plenty of pressure.

I suspect it has more to do with the dynamic stability control than the brakes themselves. Just a guess, I have no experience with E46's though. Does it happen with DSC engaged or disengaged?

I too was thinking it's more DSC than brakes. It happens with DSC engaged.

Movin' to e46.

Wish I could help, but I honestly have no clue.

lol, hopefully someone else on here can shed some light on it.

UPDATE: A few days later I get out of the car after driving and smell the unmistakable smell of brakes. The passenger side rear wheel was as hot as a frying pan. I didn't hear or feel a thing. I let it cool and limp home, now the DSC light is on and I have little brakes, like the first time this happened. Turns out the caliper was frozen (at least intermittently) and this was affecting the DSC. Best part, warranty covered the repairs.
