I started the S4 yesterday after a very long lay up (9-10 months). Of course with the battery charged the beast started on the button, however the brake pedal went to the floor and the (!) warning flashed up on the dash. The brake fluid looked low so I topped it up but it hasn't made any difference. There is no resistance in the brake pedal, although after pumping several times I did manage to build a bit of pressure but this quickly disappeared. What do you think? Hydraulic servo dead?

probably you have a oil leak somewhere and now there is some air in the brake system so first you need to fix the leak and than you need to bleed the brakes
to look for a leak check:-brake caliper on each wheel
-clutch cilinder on gearbox or pedal(this work also with brake oil)
-brake linesaudi coupe quattro b2 2.2 20vt project (573hp-626nm)
