Anti pollution error C5

Post by MrXantia »

Hi,
at random occasions my C5 2.0 petrol announces that there is an Anti Pollution error and lights up the yellow warning light in the instrument panel. It has obviously something to do with the cat, but what is the problem? Knowing the Cit rennome as I do, it could simply be an electrical error caused by water in the circuits. At a few occations it came right after washing the car.

How can I check if things are ok. Like the Lambda feeler?

Rgds.

its not neccisaryly anything to do with the cat,it could be anything related to the de-pollution system like EGR,exhaust air injection pump,coolant temp sensor etc. probably best to get the fault codes read.might even be just a software problem.
