a tip, dont shake the bottle, let it sit for 30 minutes after a car ride form shipping or from the store before you start adding to help air bubbles stay out.
you should be changing it every 2 years regardless of miles. its cheep, easy and really helps keep the system healthy.
brake flush is about the same on all cars. Some cars have ABS procedures for getting the air bubbles our and some have them for even just a bleed.

"So what you do is connect up VCDS, go into the brake module and run the output tests. It'll run the pump, then have you hold the pedal, run the pump some more, release the pedal, step on the pedal, run the pump, etc for each corner.
The instructions at myturbodiesel suggest 30 seconds which feels like FOREVER when you're sitting there with your foot on the pedal. I actually worked up to it in 5-10 second bursts and while my car isn't perfect yet its MUCH better. I think one more run and I'll have it cracked.
I've driven a lot of newer cars that had this same symptom where the pedal would sink way low and then grab all of a sudden. I hate that and I'm wondering if those cars all needed to have their ABS systems bled...
The VCDS cable from Ross Tech is 100% worth the money, asking if you can do this without the cable is the wrong question. The right question is why don't you have the cable yet?"

you can do this one person with the bottle and hose trick. I highly sugest going with ATE gold. love this stuff, much higher boiling point and a better quality fluid unlike the $3 a quart crap dot 3 at autozone, but that is still brake fluid too and is not going to hurt your car if you do use it.
Another Tip. put a 2x4 or your shoe behind the brake pedal, this keeps you from bottoming out the master cylinder, corrosion will collect beyond the normal travel of that and when you go past it, it can damage the seals and cause issues down the road, your not slowing anything down or messing anything up by doing this and it can save you from a possible nightmare of a problem of replacing the master and brake booster.
good luck you can do it. Start from the further wheel from the master and work your way up.
