Remove the air filter housing completely.
Remove the intake manifold.
Then unscrew the protective screen together with the intake manifold support from the cylinder head.
Disconnect the 1.4 lambda probe plugs and unclip the wires from the holders (fig. 2.302).
Unscrew the lambda probes on the catalytic converters using the 3337 lambda probe wrench set.
Raise the car on a lift.
Unscrew the fastening nuts of the main catalytic converter flange.
Then unscrew the bracket on the gearbox.
Next, unscrew the flange to the exhaust manifold.
Remove the exhaust manifold.
Carefully remove the exhaust pipe with catalytic converters.
Installation
NOTE: When installing the intake pipes, check the tightness of the flange connection after the catalytic converter. A loose connection in this place is the cause of cross-section of the exhaust gases. Because of this, outside air gets to the lambda probe after the catalytic converter, and the lambda regulation is disrupted.
Align the exhaust system so that there is sufficient clearance between the transmission and the subframe.
Further installation and assembly is carried out in the reverse order of removal.
