Hey everyone,I have a 2003A6 Quattro and my check engine light is on and I dida scan with the scan tool and it read out two codes, (1) evap emission control system leak very small, (2) evap emission control system purge flow fault. Does anyone have any clue on what the issues is?

 

Most likly you have a evap purge valve that is stuck part way open causing a leak in the evap system and improper flow from the evap system to the engine. Check to see if the purge valve holds vacuum. If it doesnt, replace it.

 

Thanks alot, what kind of effect can it have on my car in general?

 

If thats what the problem is it will have minimal effect on how the engine runs.

 

but it will damage the catalyst so what was the codes?? the EVAP system is there to protect over fueling and damage to the cat, its a story on its own
