2009 407sw Emission System error

Emission The system started to get the error when it was empty when the gas is loaded and the engine stays & nbsp; If the city is 50km away after night, how do I solve this problem?

I got that error once. I have 407 too. but then he went to the error code. I think it must be something related to the fuel we take. If you want to contribute to the fuel once. I did so. later it improved.

but I can not say that the contribution has improved. I think it must be something related to fuel and injector.

It may be relevant in catalytic convectors. I remember that if the topic has been opened in the forum before, I am sure you will find it if you research it. Get well soon.

I went to the service, go to the engine, the fuel has a sensor, it is broken :(
