  Note
t  After working on the exhaust system, ensure that the system is not under stress and that there is sufficient clearance to the bodywork.
t  If necessary, loosen double and single clamps and align silencers and exhaust pipe so that sufficient clearance is maintained to the bodywork and the support rings are evenly loaded → Chapter.
t  If particulate filter or pressure differential sender -G 505- is exchanged, pressure differential sender -G 505- must be adapted using vehicle diagnosis tester: Guided functions; Adapting pressure differential sender -G 505-.
t  Removing and installing exhaust manifold with turbocharger → Chapter.
t  The decoupling element in the front exhaust pipe must not be bent more than 10° - otherwise it can be damaged.
t  Renew seals, gaskets and self-locking nuts.
