Exhaust gas recirculation system on vehicles with a TDI diesel engine
- 1 - intake manifold;
- 2 - O-ring. At installation it is necessary to use a new sealing ring;
- 3 - suction pipe;
- 4 - valve of the exhaust gas recirculation system;
- 5 - bolt, 10 Nm;
- 6 - from the air cooler;
- 7 - seal. When installing, a new seal must be used;
- 8 - nut, 25 Nm;
- 9 - exhaust manifold;
- 10 - connecting pipe
The lambda sensor is used to adjust the composition of exhaust gases on vehicles with gasoline engines and is screwed into the exhaust pipe near the catalyst.
Removing
1. Raise the car and secure it on stands. Near the catalyst, remove the protective cover covering the electrical connector of the lambda sensor. Release the lambda sensor wire from the mounting brackets (see fig. in paragraph 3 of subsection 5.2). On all-wheel drive models and models with a 1.6-I engine with an automatic transmission, a lambda sensor is installed in the exhaust manifold. On models with a 1.4-I engine, the lambda sensor is installed in front near the exhaust pipe flange seal.
2. Using a wrench, unscrew the lambda sensor from the front exhaust pipe.
Installation
1. Apply a thin layer of G5 grease to the threads of the lambda sensor.
2. When installing a new lambda sensor, there is already grease on its threads. Do not lubricate the working part of the lambda sensor.
3. Screw the lambda sensor into the front exhaust pipe and tighten to 50 Nm.
4. Connect the electrical connector to the lambda sensor and secure the electrical connector wire. Close the electrical connector with a protective cover.
5. Lower the car.
