GENERAL INFORMATION

System of a retsirkulyatsiya of exhaust gases on models with the diesel SDI engine


1–lower part of an inlet collector;
2–consolidation. At installation it is necessary to use new consolidation;
3–valve of system of a retsirkulyatsiya;
4–bolt, 25 Nanometers;
5–tightening bracket;
6–bolt, 10 Nanometers;
7–connecting pipe

System of a retsirkulyatsiya of exhaust gases on cars with the diesel TDI engine


1–inlet collector;
2–sealing ring of round section. At installation it is necessary to use a new sealing ring;
3–a sucking-away branch pipe;
4–valve of system of a retsirkulyatsiya of exhaust gases;
5–bolt, 10 Nanometers;
6–from a radiator of nadduvayemy air;
7–consolidation. At installation it is necessary to use new consolidation;
8–nut, 25 Nanometers;
9–final collector;
10-connecting pipe

The lambda sensor serves for adjustment of composition of exhaust gases on cars with petrol engines and is screwed in in a reception exhaust pipe about the catalyst.

Removal

PERFORMANCE ORDER
1. Lift the car and fix on supports. About the catalyst remove the protective casing closing the electric socket a lambda sensor. Release from fastening brackets a wire a lambda sensor (see fig. in subsection 5.2 item 3). On all-wheel drive models and models with the engine 1,6-I with an automatic transmission a lambda sensor it is established in a final collector. On models with the engine 1,4-I a lambda sensor it is established ahead about sealing laying of a flange of a reception exhaust pipe.
2. Using a wrench, unscrew a lambda sensor from a reception exhaust pipe.

Installation

PERFORMANCE ORDER
1. Put on a carving a lambda sensor a thin layer of G5 greasing.
2. At installation new the lambda sensor on its carving already is available greasing. Do not grease a working part a lambda sensor.
3. Screw up a lambda sensor in a reception exhaust pipe and tighten it the moment of 50 Nanometers.
4. Connect the electric socket to a lambda sensor and fix a wire of the electric socket. Close the electric socket a protective casing.
5. Lower the car.
