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.

–  Unscrew the bolts -arrows- of the footwell zone trim.

–  Unscrew the bolts -1- and remove the cross member of the steering box -2-.

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

–  Remove right noise insulation -fastening points 1 ... 3-.   Caution Risk of damage to the vibration damper section! Secure decoupling element with transportation lock -T10404-.

–  Fit the Die transport lock -T10404-.

–  Unscrew the heat protection plate for the right cardan shaft using the socket SW 8 -3247- from its attachment -arrow-.

–  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.

–  Unscrew securing nuts from the clamp -1-. –  Remove front crosspiece from vehicle 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. –  Remove the cardan shaft → final group 0AV; Rep. gr.39.

–  Unscrew bolts -1 ... 3- and remove pendulum arm support.

–  Unscrew the right and left link rod from the stabiliser bar -arrow-.

–  Correctly position the hydraulic jack -V.A.G 1383 A- with the base -T20145- and with the support tool -T20161- underneath the subframe.   Note

To avoid having to carry out axle alignment, the subframe and the bearings must be locked with the locating pins -T10096-.

To be able to lock the subframe with the bearing, the locating pins -T10096- must be screwed to the positions -1-, -8-, -9- and -18- one after another.   Note The locating pins -T10096- can only be tightened to a torque of 20 Nm, any tighter will cause damage. –  Replace one by one the screws that fix the support block by both sides, place in its setting the locating pins -T10096- and tighten them to 20 Nm.

–  Unscrew the remaining screws -1 … 6- for the mechanical support bridge.

–  Carefully lower the subframe using the hydraulic jack -V.A.G 1383 A-. The mechanical support bridge should not hang from the steering column.   Note Make sure that when lowering the mechanical support bridge it does not touch or scrape the engine compartment, since no element is dominant.

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

–  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 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. Fitting . Continue the installation in the reverse order of removal sequence, observing 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. –  Install the subframe → Running gear, axles, steering; Rep. gr.40. –  Assemble the pendulum support. –  Fit the cardan shaft → final group 0AV; Rep. gr.39. –  Install the drive shaft → Running gear, axles, steering; Rep. gr.40.

–  Mount the heat protection plate of the right drive shaft -arrows-. –  Mount the exhaust gas temperature sender 4 -G648- → Chapter. –  Install the Lambda probe -G39- with Lambda probe heater -Z19- → Chapter –  Install exhaust gas temperature sender 3 -G495- → Chapter. –  Install the pressure differential sender -G505- → Chapter. –  Align 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.
