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

–  Release the fuel and coolant hoses from their fittings on the air duct. –  Remove bolt -1-. –  Remove air duct by lifting retaining clips -arrows- slightly.

–  Detach electrical connector -1- of the engine intake manifold flap -V157-. –  Unscrew the bolts -arrows- and remove the intake manifold flap motor -V157-. –  Disconnect the electrical connector -1- on the exhaust gas recirculation valve -N18- with the potentiometer for exhaust gas recirculation -G212-. –  Remove the electrical harness from the brackets and move to one side.

–  Screw out bolts -arrows-. –  Pull the EGR valve -N18- out at the intake manifold.   Note For greater clarity, this is shown from the rear in the illustration with engine removed.

–  Disconnect electrical connection -4- for lambda probe -G39-.

–  Unscrew the pressure hose -4- of the particle filter. –  Unscrew the lambda probe -3- with the lambda probe ring spanner -3337-. –  Unbolt the support -2- of the pressure hoses. –  Unscrew the exhaust gas temperature sensor 2, bedplate 1 -G448--5- before the particle filter.

–  Disconnect the electrical connector -arrow- for exhaust gas temperature sensor 1 -G450-. –  Unscrew exhaust gas pressure sensor 1 -G450- and remove together with the pressure hoses. –  Unbolt the front right-hand wheel.

–  Remove the centre noise insulation, fastening points -1 … 3- → Bodywork, exterior fitting work; Rep. Gr.50.

–  Remove the front right and left hand side wheel housing protections -fastening points 1 … 3- → Bodywork, exterior fitting work; Rep. Gr.50.

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

–  Unscrew the brackets -1- of the particle filter. –  Remove the brackets.

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

–  Detach right drive shaft from gearbox flange. –  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 bolts -1 ... 3- and remove pendulum arm support.

–  Remove the support bolts of the particle filter and the engine block, and remove the support.

–  Remove the front tunnel bridge -arrows-. –  Unscrew the nuts on the double clamp -1-.   Note t  Fit the transport lock -T10404- onto the damping element of the front section of the exhaust pipe with particulate filter. t  The damping element on the front section of the exhaust pipe with particulate filter should not be bent by more than 10º. Otherwise there is a risk of damage being caused. t  Pay attention to the electrical connections and routing the cables without damaging.

–  Unbolt the exhaust system bracket -arrows-. –  Make sure the cables are not damaged when removing the forward section of the exhaust pipe with the particle filter.

–  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. Installing 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 clamp for the particulate filter is fitted correctly → Anchor 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 (original parts) → ETKA (Electronic parts catalogue). In order to correctly fit the clamp, pressure pipes and particle filter brackets, approach the elements without tightening: t  Fit the gasket and the double clamp for the particle filter to the turbocharger. t  Manually screw in the injector pipe connections to the particle filter → Item. t  Fit the injector pipe bracket to the particle filter → Item. t  Screw the bracket bolts to the particle filter in by hand → Item. Tightening torque sequence for the particle filter elements: t  Clamp, 7 Nm. t  Bracket on the particulate filter → Item t  Pressure pipes → Item t  Bracket of the pressure lines on the particulate filter → Item –  Remove the exhaust gas temperature sender 2, bedplate 1 -G448- → Item. –  Install the temperature sender after the particulate filter -G527- → Item. –  Install drive shaft → Rep. Gr.40. –  Fit the bracket of the exhaust gas pressure sensor 1 -G450- on the cylinder head cap → Item. –  Align exhaust system without tension → Chapter –  Following replacement of the particle filter, the “guided functions” → Vehicle diagnosis, testing and information system VAS 5051 must be adapted.
