To bleed the forward nipple you will require a small piece of rubber tube to put on the end I the nipple, helps not to make a big mess, a 10mm spanner and 3 people.
The first person will sit in the car, his job will be to just pull out the ODB2 cable and unplug the single wire plug inline with the rest of the loom about 10cm up. Then all he will be doing is turning the ignition to the reds.
2nd person will be under the car, I just jacked up the rear and the nipple can be reached from the drivers side. Undo the nipple as far as you can with out taking it out completely and put a container underneath.
Last person will be in the boot of the car topping up the Atessa resivour as it is pumped out. The fluid will drain quite quick.
Then it's simply a matter of you turning the car on and letting the pump run bleeding the system keeping the resivour topped up as you go. I bled until there was no more air and ended up with about 2L of fluid in my bucket as my fluid was also a funny color so I wanted it all nice and red.. Then while the pump is still running close the nippe off and tighten.
The rear nipple is on the pump and bleeds via gravity so its just a matter of undoing it and letting it drain for a min then tighten.
I used Matic D.
Hope this helps
