Weird air suspension issue on F11
Hello, I could use some help with the diagnostics on a Bmw 5 series 2011 touring F11. I bought the car a month ago. It was falling on the rear on the driver side for 2 weeks. Then for 10 days it was raised at rear like suv. Today, again dropped. Level sensor fault on dash shows after a few mins of driving. Compressor pumps the rear when car starts. Twice it dropped while driving. Passanger side never dropped completely.
When mechanic looked at it he did not see any leaks from airbags. Now my though process was: Since it stayed up for 10 days I presume that there are no leaks from airbags or piping. Therefore it probably leaks from valve which gets stuck open or closed. Or maybe it is due to sensors which are defective and valves incorrectly pump or let the air out. These are the fault codes: 480DB1 Raw code: 480DB1 ECU: Air suspension Status: Test failed, Test failed (current drive cycle), Pending, Confirmed, Test failed since last DTC clear 29EB00 Raw code: 29EB00 ECU: Engine control unit Status: Test failed, Test failed (current drive cycle), Pending, Confirmed, Test failed since last DTC clear ============2============== 802096 Raw code: 802096 ECU: IPDM/Junction box (JBBF) Status: Pending, Confirmed, Test failed since last DTC clear, Test not completed during this operation cycle ============3============== 801C20 Raw code: 801C20 ECU: CAN gateway Status: Pending, Confirmed, Test not completed during this operation cycle |
