You must have a scan tool that can activate the ABS pump. I would not recommend trying to jump the pump with a 12v power source as this could potentially fry the module.

On this model, you start with the ABS pump. After that, bleed the brakes as normal. Start at the Rear Right, Rear Left, Front Right and Front Left. On rare occasions, there are still a few little air bubbles that don't come out 100%. So I've had to repeat this process from the start. I typically use about 1 liter of brake fluid and it's a good idea to fully flush all the all the old fluid out.

You depress the pedal 75-80% of the way, then run the pump. Do not go all the way to the floor.. No need to prime it even if you have just replaced the pump. There is still fluid in the system that will pull it though when the pump runs. Just make sure you have fluid topped off all the way to the top of the reservoir and check it regularly.

You can use a catch bottle for each side. For this year, the factory manual says to do the fronts at the same time. If you don't have a T connector, just use two different bottles.

You don't need a suction device for ABS bleeding. As long as the tubes are submerged below fluid in the bad fluid drain cans. This will help with allowing air to go back up the tube once the pump has stopped.

The abs pump is not hooked up to the rear brakes, so it would not pump through the 2 rear lines. The 2 rears must be done through pumping the brake pedal.

When replacing the ABS pump, you have to bleed it with a proper scan tool. If you don't, there will be trapping air in the ABS pump causing the brakes to be soft. I’m sure there are ways to do it with out, but this is the best way to avoid damage to the pump or AMB control module.

Pump is located in the engine compartment attached to the ABS control module.

We used a Ross Tech HEX+CAN VCDS cable. Our cable will scan all VW & Audis with Early OBDI 2+2 (w/ special cable), Standard OBDI and OBDII connectors.
