Replacement servo is fitted and the pedal still sinks!
Used modulator might come on Tuesday.

Ok but the EBD activity and breaking is the same like before? Nothing changed?

I made a short video how my pedal is behaving without and with engine running... and i have perfect braking

Thanks for that Sierrafery, I greatly appreciate your help. I totally agree yours is doing the same thing, but mine didn't do this until about a month ago. The brakes work fine, but I still find it disconcerting and am determined to fix it!
Now I have a new problem - the brake lights stay on all the time with the ignition on! The switch is fine, but the rod out of the new servo is not allowing the pedal to come high enough to push the switch. The rod to the cylinder piston looks as if the end unscrews for adjustment, but not the pedal end. Neither the plastic switch or the body mounting have any adjustment. The free play is roughly the same as before. I'm not in a great rush to take the whole lot apart again! All I can think of doing is to build up the button on the switch with Araldite!

Rave has answered my problem P1082! The button on the switch can be pulled out for adjustment and it does too with a satisfying click each pull. I'm quite relieved!

If the brakes are working well now with the replaced booster and the EBD doesnt it's possible that before this whole thing begun you had a restriction in the master cylinder or something if the pedal was stiff with engine running cos what you see in the video is normal behaviour when expansion chambers are involved, i'd be concerned if my pedal wouldn't do that
