Error #10720, #10721, #10705
Recently purchased a 2007 E92 with 90k miles, car runs fine with no issues. Did have a code P0171 and P0174, I figured may be a vacuum leak somewhere, possibly MAF sensor as the previous owner had a drop in K&N filter. Everything else is stock.
Previous owner had all spark plugs and coils replaced just last year. Called BMW to see if this car was effected by Fuel Pump and Injector recall, it was not... I went ahead and plugged in to get more detail, came back with Error #10720, #10721, #10705. Faulty o2 Sensors or fuel injector? |
