mystro Posted 14November, 2022 Report Share Posted 14November, 2022 Hi all, Has anyone ever changed their o2 sensor? I just got my car (997.1 Carrera S) and I understand it isn't too hard from reading online although would be good to get some local thoughts? Also where is best to buy from also? Cheers, Mitch Quote Link to comment Share on other sites More sharing options...

mystro Posted 15November, 2022 Author Report Share Posted 15November, 2022 @Joz Scan showed bank 1 sensor 2 was faulty. I ended up buying one and will replace this weekend or next. Should resolve the CEL for me. Peter M and Joz 2 Quote Link to comment Share on other sites More sharing options...
