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

–  Remove supercharging tube -2- with connecting hose -3-, releasing the brackets -arrows-. –  Disconnect connection -1- from the intake manifold air pressure sender -G71-.

–  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.   Note For improved understanding, it is shown from the rear in the illustration with engine removed.

–  Detach electrical connector -1- of the engine intake manifold flap -V157-. –  Unscrew the bolts -arrows- and remove the intake manifold flap motor -V157-.

–  Detach the connector -4- from the lambda probe -G39- and the connector -3-sender 2 of exhaust gas temperature, row 1 -G448-. –  Disconnect the electrical connector -1- for temperature sender -1 of the exhaust gas -G235-.

–  Unscrew the lambda probe -G39--1- with the lambda probe ring spanner -3337-. –  Unscrew the Sender 2 of exhaust gas temperature, row 1 -G448--2- and the pressure tube -3- from the particulate filter. –  Unscrew the bolts -arrows- and remove the particulate filter protection -4-. –  Unscrew the brackets -5- of the particle filter.

–  Remove the central soundproofing → Bodywork, exterior installation work; Rep. gr.50.

–  Unscrew the bolts -arrows- and remove the heat protecting plate. –  Remove the right articulated drive shafts → Removing and installing articulated drive shafts; Rep. gr.40. –  Remove front right hand side wheel housing liner → Bodywork, exterior fitting work; Rep. gr.63.

–  Unscrew the pressure hoses -2- towards the pressure sensor 1 of the exhaust gases -G450-. –  Loosen the exhaust temperature sensor after particle filter -G527--1-,behind the particle filter.

–  Disconnect the electrical connector -arrow- for temperature sender 1 of the exhaust gases -G450-. –  Unscrew exhaust gas pressure sensor 1 -G450- and remove together with the pressure hoses.

–  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 -A-.

–  Unscrew the hexagonal bolt from the cross member -1-. –  Release the cross member from the steering box.

–  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-.   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. –  Free 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 Installation is carried out in the reverse order of removal while noting the following:   Note t  Always 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.
