Default Bleeding Brakes on 2002 ESP A4--Do I need VAG Com, or can I bleed naturally?

I am doing the wife's rear pads today, and want to bleed and replace the fluid as well. I have read through searching this forum, that cars with the stability control need a vag com to bleed brakes. (?)

Any feedback on experience with normal two person bleeding on this subject would be appreciated.

Default nah, I did my rears without the vag.

you might need a tool to reset the piston in the rear caliper though. Otherwise you will never get them back on the rotor.

Default You only need the VAG when you're doing a full flush so you can cycle the ABS pump

But you're only bleeding the rear lines, so no VAG necessary.

But like Scott said in his other post, you will need the rear brake caliper tool. You can't just compress the rears. You have to rotate the piston and compress at the same time. You can rent the tool if you don't have it.

Default Bentley says no VAG for B6 for any bleed job, but,

Bleed sequence is weird, starting from closest and going to furthest, which is opposite of any other car I've ever done.
NO VAG cycling the ABS. While done on the B5's, no mention of it anywhere in Bentley for B6.
I always mention also that if doing full bleed flush, do your clutch, too! The clutch uses the same reservoir as the the brake system, so if you don't do the clutch, you're just re-contaminating your nice new fluid.

Default That's for bleed and flush?

When I screwed up and got air into my brake lines, I took the car to the dealer to do a full brake flush. They cycled by ABS pump.

Default Did you physically watch them do it?

Wouldn't be first:
1. Dealer said they did something and didn't do it, and/or
B. Did something they weren't supposed to (or didn't have to) do

In any case, unlike the B5, which did have it in the Bentley, the B6 has nothing in Bentley at all for cycling ABS or doing VAG COM of any sort for a bleed or full flush.
Wouldn't hurt to do it, but there is nothing that says it needs done. My guess is that dealers do it simply because they are used to having done it on the B5, and never bothered to notice they don't have to anymore. I'd bet cash none of them switch up the bleed sequence like the Bentley calls for, either.

Default I didn't watch them, but I think it was listed on the ticket

You're probably 100% right though. They're probably used to doing it one way for the B5s and never bothered changing for later model cars.

Default oh pretty good. Still have the 5 series, but looking to get rid of it.

have the for sale sticker on the back of it. Looking to get a cheap truck for a while. Something that I can beat up on since I don't have a whole lot of time right now to take care of a nice car.

How you been? Still B6'n it?
