FWIW-
In general you start with the caliber furthest from the master cylinder--in our case that's the passenger rear.
If you review the service manual, however, it describes something very different---- you start at the closest caliber and work back
1- Front left brake caliper
2 - Right front brake caliper
3 - Left rear brake caliper
4 - Right rear brake caliper
If you're flushing the braking system you'll need a bunch of pressure to get fluid through the ABS pump---at least 2bar, nearly 30psi (as stated above)
NO VCDS required
Be advised--make sure the adapter you place on the master cylinder reservoir can hold the 30 psi or you'll make a BIG mess.....
I tighten down the adapter on my pressure bleeder and wrap the top of the reservoir with an old bath towel---I've had this blow off the first time I did this..... (Motive bleeder)
ALSO
I collect some 15 oz of fluid from each caliber and needed some 2-1/2 quarts of new brake fluid to complete the flush...
If you're not flushing out the entire system set your bleeder to 15 psi and just bleed the calibers in the order shown above.
