Removing and installing pre-exhaust pipe with diesel particle filter, vehicles with left-hand drive (Fabia II, Roomster) Special tools and workshop equipment required t  Ring spanner set for lambda probe t  Tensioning strap -T10038- t  Engine/gearbox jack -V.A.G 1383/A- t  Set of tools -T10395- t  Hot screw paste -G 052 112 A3- t  Pliers for spring strap clamps t  Transport security -T10403- Removing –  Remove engine cover → Chapter.

t  -1-: Disconnect plug connection for exhaust gas temperature sender 1 -G235-. t  -2-: Disconnect plug connection for exhaust gas temperature sender 3 -G495-. t  -3-: Disconnect plug connection for exhaust gas temperature sender 4 -G648-. t  -4-: Disconnect plug connection for lambda probe -G39-.

–  Disconnect plug connection at differential pressure sender -G505--2-. –  Unscrew screw -3- and remove differential pressure sender -G505-. –  Detach the lines from the brackets at the engine and the heat shield from the particle filter, if necessary remove installed cable straps. –  Remove the lambda probe -G39- using the ring spanner for lambda probe. –  Use the set of tools -T10395- to remove the exhaust gas temperature sender 3 -G495-.

–  Remove warm-type clamp -1- between diesel particle filter and exhaust turbocharger.

–  Unscrew bolt -1-. –  Remove the sound dampening system → Body Work; Rep. gr.50.

–  Unscrew screws -1- of protective plate for right drive shaft, if present. –  Release assembly carrier in the service position and align → Chassis; Rep. gr.40.

–  Unscrew exhaust gas temperature sender 4 -G648--1- from exhaust pipe downstream diesel particle filter. –  Do not pay attention to the position -2-.

–  Release the screws -1- and then the nuts -2-. –  Remove bracket for diesel particle filter.   Note t  The assistance of a 2nd mechanic is required for guiding out the diesel particle filter. t  The decoupling element in the pre-exhaust pipe should not be bent by more than 10° - risk of damage.

t  Secure the decoupling element with the transport security -T10403- against overtensioning -arrow-.

–  Slacken the fixing nuts -arrows- of the warm-type clamp and slightly push it back from the pre-exhaust pipe. –  Carefully remove the pre-exhaust pipe with particle filter above the lowered assembly carrier together with the differential pressure sender -G505-.

–  Turn the particle filter by 180° and remove. Install Tightening torques → Chapter. Installation is performed in the reverse order, pay attention to the following points:   Note t  Before installing the assembly carrier with steering gear, make sure the seal on the steering gear is not bent on the assembly plate. In this way the footwell opening is correctly sealed, otherwise water could penetrate or noise could occur. t  Replace seals, self-locking nuts and the clamp for particle filter. t  All cable straps which are detached when removing, should be attached again in the same place when installing.

Pay attention to the fitting position of the seal -arrow- (steering nut)

Observe sequence when installing the diesel particle filter:

1.	Position diesel particle filter on exhaust gas turbocharger, loosely tighten clamp -1-
2.	Loosely screw in screws and nuts -3 … 5- by hand
3.	Tighten clamp -1-.
4.	Tighten nuts -5-.
5.	Tighten screws and nuts -3- and -4-

–  Align exhaust system free of stress → Chapter. –  After replacing the diesel particle filter, an adaption must be performed in the function „Targeted functions“ → Vehicle diagnostic tester.
