Dear Forum, I have a 2004 Cayenne Turbo with 87k miles on it. I purchased it used in February and encountered the P0130 code in late April. I replaced the bank 1, sensor 1 02 sensor (passenger side, in front of catalytic converter) in mid-May, cleared the code and all was well until now. The code has re-appeared after approximately 150 miles since replacement. Hs anyone experienced a similar issue of a P0130 code soon after the O2 sensor replacement? I welcome all suggestions. FYI - in an attempt to give back to this good community, I did post my replacement procedure in this forum. Some additional background: 1) vehicle was purchased with cat bypasses for both secondary cat's. 2) vehicle passed Illinois emissions before I purchased it 3) vehicle passed PPI before I purchased it 4) vehicle was purchased with an ECU tune from EP labs Thanks in advance!
