AmineA4

Hi guys,

So i'm having a problem with my Audi A4 04 1.8T. Since a month my car seems to shut down after 30 to 40 min ride. Ive changed my fuel pump and my fuel filter. My spark plug and coil are still good.

My garage told me my catalyst is the problem. Im having lost of power and the engine shut off after. Its an automatic.
Would a new cata solve the problem for real ? Just want to be sure before buying it !

Thanks guys here are the code Im having.
