Replacement of system of production of the fulfilled gases

Workshops prefer to replace all system at once. We cannot recommend it so, without looking because all parts of system of production of the fulfilled Audi gases can be acquired separately – even the main and additional mufflers of the all-wheel drive Audi models which in the original represent one detail. Therefore dismantle of a separate section of the pipe or the muffler can be made with little effort. So at first it is necessary to check but only then to replace.


  1. Tap serviceable mufflers a hammer on all surface, including the face parties. Thus be not too shy.
  2. If at each blow you hear a ringing sound, it means that a muffler tin still as it should be.
  3. If in some places a sound deafer, so the external cover becomes already weakened and there will be holes soon; especially if outside a cold season during which apply salt.
  4. Upon purchase of spare parts it is worth to remember that sealing laying and the self-stopped nuts have to be replaced by the new.
