Question ML 350 W164 272CV P0422

El coche funciona perfectamente, su consumo es normal y todo parece normal.
Sin embargo aparece continuamente el codigo de error P0422

Ha pasado recientemente la inspección técnica oficial positiva.

Mi mecanico dice que su diagnostico está bien y que las sondas están funcionando perfectamente.

No pasa nada.
Todo funciona perfectamente.
Sin embargo es molesto llevar la MIL encendida y que se vuelva a encender de nuevo.

sorry that my English is not very good, I try to translate with the help of Google

The car works perfectly, its consumption is normal and everything seems normal.
However, error code P0422 continuously appears

The official official technical inspection has recently passed.

My mechanic says that his diagnosis is fine and that the probes are working perfectly.

Nothing happens.
Everything works perfectly.
However, it is annoying to bring the MIL on and turn it on again.

Greetings and thanks for reading

Welcome to the forum! Please take a moment to visit the User Control Panel and update your profile to include your car model and year, and your location (at least country). This information will then appear below your name and avatar on the left side panel next to each post you make. This will greatly help others to give you better information. If you are using the mobile version of the site, you will need to switch to the "full" version to get to the User Control Panel.

P0422 is either "0942 The efficiency of the right catalytic converter is insufficient. (function chain)" or "0946 The efficiency of the left catalytic converter is insufficient. (function chain)". I would say you need to replace at least on catalytic converter.
