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 Item -1- can be disregarded. –  Remove retaining clips of the hose. –  Carefully and in a straight line, separate the hose from the connecting sleeves (the sleeves of the pressure sender break easily).

–  Disconnect the connector -2-, undo the bolt -3- and remove the pressure differential sender -G505- with bracket in the direction of the -arrow-. –  Unscrew the bolt -1- from the upper support of the particle filter mount.

–  Remove centre noise insulation -fastening points 1 ... 3-. –  Unbolt the front right-hand wheel.

–  Remove right noise insulation -fastening points 1 ... 3-.

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

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

–  Unscrew the nut -arrow- from the connecting rod on the right side of the stabilizer.   Caution Risk of damage to the vibration damper section! Secure decoupling element with transportation lock -T10404-.

–  Fit the Die transport lock -T10404-.

–  Remove nuts -1- and -2-. Nuts -1- can be reached with ratchet wrench 13 mm -T10384-. –  Removing the bracket of the particle filter.

–  Unscrew bolts -2- and -3- of the pendulum arm support.   Note Item -1- can be disregarded.

–  Press engine/gearbox assembly to lock carrier and support using pendulum support as shown in illustration. A -  Collared bolt M10x35

–  Unscrew the right hand drive shaft from the drive 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. –  Remove the thermal protection plate of the steering box assembly. –  Loosen nuts for clamping sleeve -1- and slide clamping sleeve backwards.

–  Unscrew the nuts -arrows- and remove front cross member from the floor of the vehicle.

–  Unscrew bolts -arrows- for bracket. –  Partially remove the front part of the exhaust tube with particulate filter and position it over the steering box.

–  Remove particulate filter by turning 180° around its own axis. Fitting . l  Tightening torques → Chapter Installation is carried out in reverse order, noting the following:   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 flexible hose sleeves and the line of the turbocharger air system must be free from oil and grease before assembly. t  Secure all hose connections with the correct hose clips (same as original equipment) → Parts catalogue.

–  Observe sequence when installing particulate filter:

1.	position particulate filter on turbocharger and secure clip -1- loosely
2.	screw bolts -2 … 5- in loosely by hand l  particulate filter and retainer must be able to move
3.	tighten clip -1-
4.	Tighten the bolts -2- and -5-.
5.	Tighten the bolts -3- and -4-.

–  Install pendulum support → Chapter. –  Fit the drive shafts → Running gear; Rep. gr.40.

–  Mount the heat protection plate of the right drive shaft -arrows-. –  Install exhaust gas temperature sender 3 -G495- → Chapter. –  Mount the exhaust gas temperature sender 4 -G648- → Chapter. –  Install the Lambda probe -G39- with Lambda probe heater -Z19- → Chapter –  Install the pressure differential sender -G505- → Chapter. –  Align exhaust system free of stress → Chapter. –  After renewing particulate filter, carry out adaptation in „guided functions“ operating mode → Vehicle diagnostic, testing and information system VAS 5051.
