Removing –  Detach the outer -1- and inner -2- engine covers, by pulling them evenly upwards.

–  Remove the switching valve for the radiator for the exhaust gas recirculation -N345-- 2- from its bracket. –  Detach the electrical connectors -1- and leave the wires free. –  Unscrew bolts -arrows-.   Note Disregard: -Items 3, 4, 5, 6-.

–  Uncouple the electrical connector -4- of the lambda probe -G39- and free the electrical wire.   Note Disregard: -Items 1, 2, 3, 5-.

–  Undo the lambda probe -G39--3- using the socket wrench E/C 22 -T20202A- and the "ratchet 1/2"" x 9-12" -VAG 1331/1-. –  Unscrew the temperature sender before particulate filter -G506--5- with 17 mm socket wrench -T20211- and "Ratchet 1/2" x 9-12" -VAG 1331/1-. –  Unbolt the support -2- of the pressure hoses. –  Unscrew the pressure hoses -4- of the particle filter with the socket wrench E/C 17 -T20211- and the "ratchet 1/2"" x 9-12" -VAG 1331/1-. –  Release the clamp -1- for the particulate filter and remove it.

–  Remove the air conduit cover by releasing the side tabs -arrows-.

–  Unclip the air conduit in the lower part by releasing the tabs -arrows-. –  Remove the lower section of the air duct together with the air hose.

–  Remove central noise insulation -Attachment parts 1 ... 3-.

–  Remove the front right wheel. –  Remove the noise insulation on the right side -Attachment parts 1 ... 3-.

–  Remove the left hand side air hose; to do this, lift the retaining clips slightly -arrows-.

–  Remove the right hand side air conduit hose, to do this, lift the retainers slightly -arrows-.

–  Detach the electrical connector -2- in the supercharger pressure sender -G31- and input air temperature sender -G42-. –  Unscrew the bolts -1- and -3-. –  Dismount the air channelling hose in the air flexible conduit strap -4- and remove it downwards.

–  Disconnect connector -1-. –  Unscrew the bolts -arrows- and remove the fan frame downwards. Push the engine to the back for this purpose.

–  Remove front crosspiece from vehicle underbody -arrows-.   Note The flexible pipe connection (de-coupling element) in the front exhaust pipe must not be bent more than 10° - otherwise it can be damaged. –  Loosen exhaust system from double clamp -1-. –  Remove the cardan shaft → final group 0AV; Rep. gr.39.

–  Unbolt the pressure pipe -2- using the articulated wrench E/C 17 -T20212-. –  Unbolt the temperature sender after the particulate filter -G527--1- using the articulated wrench E/C 17 -T20212-.

–  Unscrew the insulating panel for the right half shaft from its mounting at the angular gears -arrows-.

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

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

–  Unscrew the suspension element -arrow-.

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

–  Undo bolt -1- and remove the cross member -2- from the steering box.

–  Correctly position the hydraulic jack -SAT 1040- with the base -T20145- and with the support tool -T20161- underneath the subframe.   Note

To avoid aligning the wheels you must immobilise the mechanical support bridge and the consoles with the centering guide -T20150- .

To fix the mechanical support bridge with the consoles you must thread one after the other the centering guides -T20150- in the positions -1-,-8-,-9- and -18-.   Note The centering guides -T20150- can only be tightened, at maximum, at a torque of 20 Nm, otherwise the anchoring stud thread may be damaged. –  Replace one by one the screws that fix the support block by both sides, place in its setting the centering guides -T20150- and tighten them to 20 Nm.

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

–  Lower a little the mechanical support bridge with the help of the hydraulic jack -SAT 1040-. 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.

–  Unscrew nuts -1- and -3-, as well as the screw -2- and remove the particle filter support.   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. –  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 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. Fit the gasket and the double clamp for the particle filter to the turbocharger. –  Fit the temperature sensor after particle filter -G527- → Chapter. –  Install exhaust pressure sensor 1 -G450-. → Chapter –  Install Lambda probe -G39- → Chapter. –  Fit the temperature sensor in front of the particle filter -G506-. –  Mount the right short axle → Rep. gr.39 –  Fit the cardan shaft → final group 0AV; Rep. gr.39. –  Install the exhaust system and align free of stress → Chapter. –  Following replacement of the particle filter, the „guided functions“ → Vehicle diagnostic tester must be adapted.
