Burning out

Did you turn off traction control? You might not be able to break the wheels loose anyways... but if you REALLY want to do it, hold the brake pedal with your left foot, then rev the engine a little and let go of the brake. Don't do this TOO much, but its not like you'll blow up the engine or tranny.
If you want to do a burnout in the 330i then find a T-intersection with a nice hill accross it and turn left (that's the far lane for you American's) up the hill. This way you don't damage your torque converter by holding the engine on the brakes and trying to do a line-locker. The motion of a big sweeping turn up a steepish gradient means that the inside rear is burdened with much less of the car's weight and, hey presto, you have yourself a nice mechanically-sympathetic burnout. The only thing you'll stuff up is the tyre...and the diff if you keep doing burnouts with the same wheel!
You do have the wrong transmission for doing burnouts. With that said, if you really want to try to do a burnout, you need to completely disable traction/stability/braking control. Do this by holding the button down for 4 or 5 seconds until the brake indicator turns on. Then everything except ABS is defeated. If you press it briefly you only turn off stability control.
Even then, you won't do a firey, smokey burnout, you will just be able to chirp the tires when you pull out, unless you are turning as someone mentioned above.

Hmmm, even 2 grand on the tacho wouldn't be enough to light up the rears with the brakes on. You'd need at least 3 - 4 thousand RPM and even then you would have to let off the brakes and stand back on them to get the rears loose. It's fun but it is just so hard on the car and I can't bring myself to do it.
Having said that, the E38 740il does awesome burnouts if attempted in the manner in which I originally posted (turning up a hill). Now that is fun and there's no harm done! So I reckon with 170KW the 330i would pretty much do the same.

Autos aren't really good for burn-outs. You should just wait for a wet day or do the brake-torque thing as suggested above...but that technique is hard on the car.
Personally, if it's a sub-40 degree day, I don't need to rev up and drop the clutch to spin the rear tires. I can do cool burnouts just by engaging 1st and going full throttle. Or if I am making a turn and floor it, it will do a burnout also...I think in this case, you need good low-end torque.

Yeah, you need quite a bit of low end torque to do a burnout in an automatic. You'll probably have trouble doing a burnout even while doing a brake-torque like epj3 described. The problem is that you don't have a bunch of low end torque at less than 2000 rpm or so and BMWs have tight torque convertors that aren't going to allow the engine to rev up much with the foot on the brake and the gas floored. Without the ability to get the RPMs higher, you won't develop the torque you need to do a good burnout. My friend and I tried many times with an automatic E36 318i and an automatic E36 325i. We could never get either of those cars to even chirp the tires no matter what we did (we actually ended up blowing up the differential in the 318i). My automatic Camaro will smoke the rear tires by just flooring it without even brake-torquing it, but it has gobs of low end torque. Burnouts are all about the torque.
And for the record, brake torquing an automatic is easier on a car than dropping the clutch in a manual car. When you brake torque an automatic, you are loading the drivetrain gradually. When you drop the clutch in a manual, you are hard shock loading a previously unstressed clutch, transmission, driveshaft, u-joints, differential, and rear half shafts. It's very easy to break things with that kind of shock loading. Think about the strain you put on those parts by suddenly engaging a crankshaft rotating at 4000+ RPM to all of those stationary parts. Think about the forces and harmonics you instantly place on your crankshaft and crank bearings. Ouch!

Justing makes a very good point with the forces you can exert on your car. 10 seconds of fun could end up 10 thousand in repairs... I say if you want to do that kind of stuff get your self a 70s muscle car. Such as the Hemi-Cuda or a Dodge Challenger, or Chevy SS, or a Road Runner.. just a nice muscle car out of the 70s would be great for burnouts and these cars are made to handle the abuse.
burnouts are great for the manaul. (haha) The clutch springs and flex disk dampen the sudden force on all that was listes above a little bit.
My tires hate me, but my BMW loves me. I rip tire like its my job. (i'm sure everyone is picturing me at every red light lighting up the tires... not at all... there is a time and place for these things) Love the sound and feel of it. I don't do it much in the winter though. With the windows up, you can't hear the scream of the rubber as much. BMW's are TOUGH! atleast the e30's are...
on my wedding day, as a gift to myself before the wedding, i did a brake stand on the way to the church. Smokey smokey stand still two-wheel burnout. (fun to master with a clutch) It was phenominal. I'm not sure why i'm rambling. I'm not nuts behind the wheel, but theres nothing better than the sound of rubber against pavement along with the rumble/scream of the engine. I love watching flicks of people burning out and doing doughnuts especially when they have a LSD.... (Nothing worse than a one wheel burnout.) Anyone have any good clips??
