Removing and installing parts of exhaust system
  Note
t  Vehicles with engine code BLY, BVZ, BHD, BMB comply with emission standard EU 2. On these vehicles some emissions-related components are not fitted, e.g. exhaust gas recirculation system, NOx sensor control unit -J583-, Lambda probe 2 -G108- and Lambda probe 2 after catalytic converter -G131-. Note this when working on the exhaust system.
t  Renew gaskets and self-locking nuts.
t  After working on the exhaust system, ensure that the system is not under stress and that it has sufficient clearance from the body. If necessary, loosen clamp and align silencers and exhaust pipe so that sufficient clearance is maintained to the body at all points and the mountings are evenly loaded.
