hqstu 780 Report post Posted July 2, 2016 Hi All, Sorry if this has been discussed before but a quick search didn't really show up anything... Head under the hood this weekend doing Waterpump, thermostat, vanos seals, valve cover gaskets when it dawned on me that this car (and my previous 530i M54 - both NZ new) don't have the post cat oxygen sensors. The connectors on the top of the engine go nowhere... Can anyone explain? I'm guessing BMW NZ deleted them as not required under our (then) emission rules? What was done to the engine management to cater? Cheers, Stuart. Quote Share this post Link to post Share on other sites
