Hey i got this code from one of my 00 1.8TQ, and i was just wondering which of the two O2 sensors it is. Also do you guys think that i would have to replace it or what??

16524 [&:] O2 Sensor Circuit - Slow Response (Bank 1 Sensor 2) B

 

sounds like a lazy sensor
its the post catalitic one too.
clear the code and if it comes back replace it.

 

judges? is that correct?

 

Yes it is the rear O2 sensor. Bosch direct replacement sensor is $130.62 shipped at my store.

Do what _Adrian_ suggested first, clear the code and run the car with known good premium gas and see if it returns. If the sensor is completely gone you will feel it in your MPG.

ecartoys,
do you have the bank2 sensor2 for 97 A4 Q 2.8?

 

If its the post catalytic converter sensor.. screw it... it does nothing but tell you the cat is working.... You can clear the code... buy a new one.. or not.. doesnt
really matter.

Now if your emissions get tested you may want to replace depending on how they test you.
