Crank no start, 11 codes, looking for a place to start
Hello,
2011 35i (122k miles) ran without issue until Sunday night, when it presented a "crank no start" condition. I am getting 11 codes. 277A - Hot film air mass meter signal: Electrical fault 2C58 - Charging pressure control: Switch-off as consequence 2C89 - Blow-off valve, activation: Short circuit to earth 2D52 - VANOS solenoid valve, intake, activation: Short circuit to earth 2D9C - Exhaust VANOS solenoid valve, activation: Short circuit to earth 2E4B - Exhaust flap, activation: Short circuit to earth 300C - Intake camshaft sensor, electric: short circuit to B+ 300E - Exhaust camshaft sensor, electrical: short circuit to B+ 332F - Terminal 87_2: No voltage 3400 - Engine oil pressure control valve, activation: Short circuit to ground 3492 - Engine-oil pressure sensor, plausibility: Pressure too high before engine start Based on that I would say there's a short but I am hoping someone might know of a common issue with these codes and could hopefully point me in the right direction for trouble shooting. Thank you! Last edited by MagnusIsACat; 05-14-2024 at 08:21 PM.. Reason: Misspelled 87_2 as 97_2 |

check the oxygen sensor wiring behind the throttle body. I drove my X5 to the side of my house to make room to work on my X3. I went to start it and nothing, Crank No start. I thought there may be a leak in air supply. I removed the Rubber boot with resonator and to my surprise there was a bundle of chewed up wires. My best guess: the wires are long and they fell down and got caught in front driveshaft. I repaired the wires and it started right up. I did make sure the connectors were secure and would not fall again.
