Removing . –  Remove the engine cover upwards -arrows-.

–  Uncouple the electrical connector -5- for the exhaust gas temperature sender 3 -G495- and free the electrical wiring from their fastenings. –  Uncouple the electrical connector -2- for the exhaust gas temperature sender 4 -G648- and free the electrical wiring. –  Uncouple the electrical connector -4- from the Lambda probe -G39- and free the electrical wiring from their fastenings.

–  Unscrew lambda probe -G39--3- with SW 22 socket wrench -T20202A-. –  Loosen and remove the clip -2- between the particle filter and exhaust gas turbocharger.   Note Disregard: -Pos. 1-.

–  Disconnect the connector -2-, undo the bolt -3- and remove the pressure sensor 1 of exhaust gases -G450- with bracket in the direction of the -arrow-. Place on the particle filter. –  Unscrew the bolt -1- from the upper support of the particle filter mount.

–  Fit the centre noise insulation -fasteners 1 ... 3-.

–  Remove the right wheel housing -Fixing parts 1 ... 3-.

–  Unbolt heat shield for right drive shaft -arrows-.

–  Unscrew exhaust temperature sensor 4 -G648--1- with flexible-head wrench SW 17 -T20212-.

–  Unbolt right half shafts from gearbox flange or the intermediate bearing. –  Tie the left half-shaft leaving it suspended. –  Turn the steering toward the right. –  Tilt the right-half shaft forwards and strap it to the sill -arrow-, as shown in the image.

–  Unscrew bolts -1 ... 3- and take pendulum support out.

–  Remove nuts -1- and -2- and detach bracket for particulate filter.

–  Unscrew securing nuts from the clamp -1-. –  Remove the front cross member from the underbody -arrows-.   Note The mounting on the front section of the exhaust pipe with particle filter should not be bent by more than 10° otherwise there is a risk of damage.

–  Unscrew the suspension element -arrow-. –  Partially remove the front part of the exhaust tube with particulate filter and position it over the steering box. –  Remove the exhaust gas temperature sender 3 -G495- → Item.

–  Remove the particle filter by turning it by 180° clockwise. In doing so, slightly press the engine / gear unit to the front and remove the filter between the tunnel and the mechanical bridge support unit. Installing . Continue the installation in the reverse order of removal sequence, observing the following: l  Specified torque → Chapter.   Note t  When replacing the particle filter, the transport protection on the coupling element should not be removed until just before fitting. t  Fit the cable clamps in the same position as they were. t  Ensure that the double clamp for the particle filter is correctly fitted. t  Replace seals, gaskets and self-locking nuts. t  The sleeves for the hoses and the supercharger air flow tubes should be free of oil and grease before fitting. t  Secure all hose connections with the correct hose clips (same as original equipment) → Parts catalogue. –  Install pendulum support → Chapter. –  Fit the complete half-shaft → Rep. gr.40. –  Fit the heat plate of the cardan shaft → Rep. gr.34. –  Install exhaust gas temperature sender 3 -G495- → Chapter. –  Install exhaust gas temperature sender 4 -G648- → Chapter. –  Install Lambda probe -G39- → Chapter. –  Aligning exhaust system free of stress → Chapter. –  Following replacement of the particle filter, the „guided functions“ → Vehicle diagnostic, testing and information system VAS 5051 must be adapted.
