Instructions: After installing the exhaust system components, it is necessary to check for internal stress in the system and for sufficient distance between the system components and the body. If necessary, loosen the double clamp and align the exhaust pipe and muffler so that there is sufficient distance to the body and the fasteners are loaded evenly. Replace the self-locking nuts. When replacing the particulate filter or the exhaust pressure sensor 1-G450-, it is imperative to adapt the exhaust pressure sensor 1-G450- via the tester: guided functions; adaptation of the exhaust gas pressure sensor 1-G450-.
Remove the battery and the battery mounting pad. Remove the air filter housing. Disconnect the lambda probe connector "G39" "3" and the exhaust gas temperature sensor connector 4 G648- "2".
Disconnect the exhaust gas temperature sensor connector 3 "G495" "1" (fixed behind the holder). Disconnect the connectors from the holders and remove the cables from the holders on the front wall of the water drainage box "2" and the turbocharger.
Disconnect the connector, unscrew bolt "2" and remove the bracket of the exhaust gas pressure sensor 1 "G450", including the sensor by moving it in the direction of travel. Remove the exhaust gas pressure sensor 1-G450- on the particulate filter.
Unscrew the "arrow" mounting bolt on the upper bracket of the diesel particulate filter. Remove the soundproofing tray. Remove the subframe with the steering gear.
Loosen clamp "1" connecting the particulate filter and turbocharger. Unscrew the nuts securing the particulate filter to the bracket using the open-end ratchet wrench "T10384".
Loosen the nuts securing the "arrow" of the particulate filter bracket "A" to the cylinder block. Leave the bracket on the cylinder block.
Front wheel drive cars
Unscrew bolts "1" of heat shield "A" above the right drive shaft and remove the shield.
All-wheel drive vehicles
Unscrew the bolts "1" of the heat shield "A" of the right drive shaft using the 8 mm socket "3247". If necessary, slightly press the diesel particulate filter upwards to gain access to the rear bolt.
All
Secure the detachable element of the front part of the exhaust system with the transport protection device "T10404". Loosen the fastening clamp on the exhaust pipe. Do not remove the clamp. Remove the particulate filter bracket "A". Move the fastening clamp in the direction of the exhaust pipe. Remove the particulate filter with the exhaust pipe by moving it downwards. Do not damage the wires or other components.
Installation
Secure the detachable element of the front section of the exhaust system with the transport protection device "T10404". Install the particulate filter bracket in place at the bottom of the cylinder block and tighten the bracket fastening nuts by hand. Install the particulate filter on the bracket. Secure the exhaust pipe to the propeller shaft or body using suitable means. Screw in the fastening bolt on the upper bracket of the particulate filter by hand. Slide the double clamp into the correct position on the exhaust pipe. Pull the electrical cables of the temperature sensors upwards. Install the clamp on the turbocharger in the correct position and tighten it. Tighten the fastening bolts in the following sequence.
1. Lower bracket of the diesel particulate filter to the engine block.
2. Diesel particulate filter to the lower bracket, use the open-end ratchet wrench "T10384".
3. Diesel particulate filter to the upper bracket.
