on my 2006, B6, Sport, the brakes have been getting progressively worse over past year. Now, pressing the brake pedal down gives a little bite and then it goes very soft until it close to the floor and going hard. The car is now at VAGTune in Aylesbury and they have bled the brakes several times in past month and do not get any air out. Neither does the biting point come up away from the floor. They have also exercised the ABS but still brakes only bite close to floor. I predicted this was a master cylinder issue but they have not checked that yet. I also feel that he brake servo is not assisting the braking force. All callipers and hoses are in good condition and there's no loss of fluid level or leaks from any of the circuit..
Does anyone have any experience of symptoms like this?
