 Note !  (Picture 4) illustrates the type of piston fitted to this type compressor on late 2011> Audi's & Bmw's models generally, (Picture  5) illustrates what a worn piston seal generally looks like but if your seal is in tact it may have become hardened due to heat and lost some of its flexibility to seal which can  reduce the outgoing pressure of your wabco unit ! the air dryer chamber on your unit contains 2 x filters and a amount of granules to remove condensation from the outgoing air pressure ! over time the granules become fully absorbed with water not allowing the outgoing air pressure to be dry thus causing problems with other components ! however if you still feel your air dryer filtration is in good condition then please view our stand alone piston seal repair kit in our other listings or contact ourselves for further advice.
