2002 VW Jetta very low mileage codes P0420 and P1296 help needed! Sign In

Recently failed emissions test- Need help!
I have a 2002 VW Jetta with ONLY 48,000 miles on it. I just had the water pump and thermostat replaced. Now after failing emissions the P0420 and P1296 popped up. The mechanic who replaced the water pump was even shocked that the P0420 code was coming up because of the very low mileage on the car. Please help! Is it really the converter? What other options should I explore? I just dropped $800 on the water pump/thermostat so trying to find the most cost effective solution. The car was previously owned by a family member who purchased it from the dealership and no other work has been done on the vehicle besides standard maintenance. Any advice or how I should go about fixing would be useful
Thank you

Which engine? P1296 has to do with the engine coolant temperature sensor or how the coolant temperature is being regulated. That code could have set from your leaking water pump or possibly the incorrect thermostat is installed?

Your mechanic needs to monitor the engine coolant temperature with his scan tool and see what is going on.



Is the catalyst rattling if you hit with the flat part of your hand?
