Hello- I have a 2008 Audi A3 which I recently had chipped. (best decision ever) The car has 65k on the motor and I'm trying to be proactive and replace some parts (fuel filters, O2 sensors, PCV valve) I am very confused as to which PCV or Pressure Regulator Valve I need to order. Can anyone help with a model number or link?

Also, does anyone know if I should go ahead and replace the O2 sensors or wait?

Thanks

 

Hello, I'd like to help answer some of your questions. The pcv valve doesn't look like your older traditional type. Our techs call this a labyrinth, it bolts to the valve cover and does the same job as the traditional pcv valve. They plug up quite a bit though. It is 59.63 for the 4 cylinder one I think it is. The fuel filter is 51.00 and appears to be in with the in-tank fuel pump. A new fuel pump would come with the filter from what my picture tells me. I'd need your vin# to double check for the correct parts.

I asked a tech, he said the 02 sensors are replaced when they fail. He didn't state any mileage interval for replacement on a maintenance schedule.

I hope this helps, please let me know if you have any questions. Thanks, Jeff.
