Removing

–  Release the fasteners -arrows- to remove the central soundproofing panel.

–  Unscrew the bolts -arrows- and remove the heat protecting plate. –  Remove right hand articulated shaft → Running gear, shafts, steering; Rep. gr.40.

–  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-.

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

–  Separate the clamps -arrows- and remove the supercharger hose -1-.

–  Detach electrical connector -1- of the engine intake manifold flap -V157-. –  Unscrew the bolts -arrows- and remove the intake manifold flap motor -V157-.   Note For improved understanding, it is shown from the rear in the illustration with engine removed.

–  Disconnect the electrical connector -1- on the exhaust gas recirculation valve -N18- with the potentiometer for regulating exhaust gases -G212-. –  Remove the electrical harness from the brackets and move to one side. –  Remove bolts -arrows-. –  Remove the exhaust gas recirculation valve -N18- of the intake manifold.

–  Disconnect the connectors -1-, -2-, -3- and -4- and remove them from their housings.

–  Undo the pressure pipe -3- of the particulate filter using the socket wrench E/C 17 -T20211-. –  Undo the lambda probe -G39--1- using the socket wrench E/C 22 -T20202A- and the "ratchet 1/2" x 9-12" -VAG 1331/1-. –  Unscrew the bolts -arrows- and free heatproof plate of the particulate filter -4- without removing it.

–  Undo the exhaust gas temperature sender 2, bench 1 -G448--2- using the socket wrench E/C 17 -T20211- and the "ratchet 1/2" x 9-12" -VAG 1331/1-.

–  Disconnect the electrical connector -arrow- for temperature sender 1 of the exhaust gases -G450-. –  Undo the nuts -1- and remove the exhaust gas pressure sensor 1 -G450- together with the pressure pipes. –  Remove the heatproof plate of the particulate filter.   Note If it is not possible to remove the heatproof plate, place it to one side and then lower it together with the particulate filter.

–  Unscrew the brackets -5- of the particle filter.

–  Secure the steering wheel; to do this, put the wheels straight and secure it -arrow- with adhesive tape.

–  Remove the plastic bolts -1-. –  Remove cover -2-.

–  Unscrew the hexagonal bolt from the cross member -1-. –  Remove the steering box crosspiece by pulling in -direction of the arrow-.

–  Release the steering bar heads from the wheel bearing housing.   Note Leave the hexagon nut on the ball joint threads to protect them.

–  Unscrew the hexagonal nut -1- from the link bars -3- on both sides of the vehicle. –  Separate the link bars -3- from the stabiliser bar -2-.

–  Unscrew the bolts -1- and -2- of the pendulum support from the gearbox.

–  Correctly position the hydraulic jack -SAT 1040- with the base -T20145- and with the support tool -T20161- underneath the subframe.   Note The terminals of the support tool -T20161- threaded shafts should insert into the swinging arm holes.

–  Remove the rear bracket bolts -5-. –  Remove bolts -1 ... 4-, and lower the sub-frame. Make sure that no elements can be damaged when doing so.

–  Unscrew the nuts on the double clamp -1-. In that case it is not necessary to unscrew nuts -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.

–  Remove the support bolts of the particle filter and the engine block, and remove the support. –  Remove the front exhaust section from the tunnel bridge → Item.   Note t  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. t  Pay attention to the electrical connections and routing the cables without damaging.

–  Remove the particulate filter between the floor tunnel and the front strut. Installing Continue the installation in the reverse order of removal sequence, observing the following:   Note t  Renew seals, gaskets and self-locking nuts. t  Secure all hose connections with the correct hose clips (same as original equipment) → Parts catalogue. t  Fit the cable clamps in the same position as they were.
