P0431 Warm Up Catalyst Efficiency Below Threshold Bank 2
The word Catalyst, means that the catalytic converter needs to be replaced because some of the warm up catalyst is not working initially when the car first starts up before it warms up.

Good luck on this repair.

Okay so I'm having problems with my 2001 vw passat v6 4motion wagon . when i start it up she sounds great but when i put it into drive and try to take off she sputters.. even when im driving down


could be time for a tune up also check the spark plug holes for oil if the valve cover gasket are leaking into there can also have a bad coil if the check engine light is on have it scanned at a auto parts store (most do it for free)the code can lead you to the bad cylinder exp code p0301 is cylinder number one p0306 is cylinder number six and the same for p0302-p035
