The car is fixed, but the brake pedal is a bit soft.
The problem did turn out to be the servo, so the new (used servo) is now on the car as well as the new master cylinder.
He power bled the brakes for a long time from all 6 nipples?, but it still feels a bit soft.

I seem to remember from changing the brake fluid on my previous D2 that D2's have to go on the Audi dealer machine to bleed the ABS unit properly? Is this right or am I making stuff up :)?

Have you got MJs brake block though, you're not on the old list of recipients?

My experience of it, FWIW : http://forum.a8parts.co.uk/showthrea...147#post169147

If the system has been open at the master cylinder then you'll need VCDS to cycle the ESP return pump and then a couple of ABS-assisted emergency stops to fully purge all the air out. The latter is obviously pretty challenging on dry roads with spongy D2 brakes!

I still want to get the MJ block, I missed the original group buy.

Ah yes, that rings a bell, thanks 👍
Maybe he did do the ESP return pump, I’ll try the ABS braking to see if that cures the pedal softness. Thanks Mikki +++
