Hello All,
Back to PW after a long gap. I am looking for some help with P0422 (Main Catalyst: Bank 1: Efficiency Below Threshold ) DTC on my B5. I have also intermittently had P0130 (Oxygen (Lambda) Sensor B1 S1: Malfunction in Circuit) and the SAIP DTC (don't remember the code).
I am due for emmisions. I cleared the ECU DTC's. Several readiness codes were not set initially after clearing the DTC's. I followed the instructions from here:

After following the process, the CEL came back on for P0422 and the readiness code was not ready for secondary air pump. You are allowed to have one CEL, one readiness code not set as long as it is not Catalyst related in my state. Unfortunately that is true in my case.
I have not seen any drop in my performance. May be the cat is bad. I have also read that it is possible to set the readiness codes using vag-com.

Any thoughts? I hate to spend on a new cat converter on a 14 year old B5...
Thanks!
