I reached out to 034 Motorsports to see if they can provide some insight because I got some trouble codes from my Audi. First off the performance is A1 for this product because I purchased it with a spacer. Now for the troubles. I scanned my fault codes and found that I have P0140, P01114 for my rear O2 sensor. I just wanted to check with you guys to see if these codes lead to failing rear o2 sensor. I live in a emissions state so I can't get around it. :(

P0140 is possibly not relevant to the HFC/spacer. This could definitely be a failing sensor. I recently replaced my secondary O2 sensor, with this one:

Your second fault code (P01114) is a typo...

Apologies for the typo. How do you like this sensor and did you get similar codes to?

Edit: How come the price is so drastic between the OEM and this one? Is it because of the wiring since it looks longer?
