MeloB M Hi All, I just changed the EGR cooler (error P-2457 was present and confirmed by the dealer's diagnosis which then provided the part #) on my 2012 E70 and cleared the code and CEL afterwards. Took it for a spirited drive to test and the CEL came back after starting the car. Below are the codes I got from INPA. I'm having a hard time figuring out what these mean. Am I doing something wrong? Appreciate the help. Thanks, Mel #1 · Nov 4, 2017 Hi All, I just changed the EGR cooler (error P-2457 was present and confirmed by the dealer's diagnosis which then provided the part #) on my 2012 E70 and cleared the code and CEL afterwards.

Or isn't fully connected? Newtis.info perhaps? Engine electrical... The '9' code is some AC thing, I'd not be too concerned with that at this point. #3 · Nov 4, 2017 4b73 is heating, crankcase ventilation. Could your PCV valve heater be unplugged? #4 · Nov 5, 2017 Where is the PCV valve located? I don't see any unplugges wires hanging around but will make sure to go over them once more Insert Quotes Post Reply
