Removal and installation the catalytic converter/diesel particulate filter (Skoda Yeti 5L)

Note: On diesel models, the catalytic converter and diesel particulate filter are a single, non-separable module.

1. The installation details of the catalytic converter are shown in the illustrations. Before installing the old lambda probe or exhaust gas temperature sensor, apply high-temperature grease G052 112A3 to its threads, making sure that it does not get into the openings in the lambda probe housing. The threads of the new lambda probe must be lubricated with assembly grease.
