Customer Question

Hey how are you doing. I'm having a problem with an 09 tdi Jetta. It keeps coming up with a po47a code. We replaced the sensor suggested by vw but keeps coming up with the code. Part #076-906-051a is the piece on the upper left side of the motor. Any onsite would be greatly appreciated

Did you replace the one in front of the firewall or closer to the coolant reservoir ?

Customer: replied 2 years ago.
It could go either way. It's on a bracket located at the edge of the valve cover to the right of the coolant reservoir and just infront of the firewall
