2013 328i Drivetrain Malfunction and more
So I decided to take my car on a five hour road trip. On the way there towards the end I noticed the car to shake at low speeds, and drive smooth at high speeds, so I thought it might've just been the roads. On the way back, I was driving in eco pro and had to stop pretty abruptly driving off a short and very steep highway exit ramp. The car shut off from the auto start/stop function, and right when it turned back on, a warning came on the iDrive screen saying "Drivetrain malfunction drive moderately. maximum drivetrain output not available. consult service center."
I pulled over and turned the car off, and waited about ten minutes to turn the car back on. The warning did not come back up, and I drove the rest of the way (3 hours) in comfort mode without the warning coming on again. When I got home I scanned the car and it threw a bunch of codes: ============1============== CDA904 Raw code: CDA904 ECU: Engine control unit Status: Test failed, Test failed (current drive cycle), Pending, Confirmed, Test failed since last DTC clear ============2============== 123516 Raw code: 123516 ECU: Engine control unit[Archive (inactive)] Status: Confirmed, Test failed since last DTC clear ============3============== 120408 Raw code: 120408 ECU: Engine control unit Status: Pending, Confirmed, Test failed since last DTC clear ============4============== 801C20 Raw code: 801C20 ECU: CAN gateway Status: Pending, Confirmed, Test not completed during this operation cycle ============5============== 481F8B Raw code: 481F8B ECU: TPMS Status: Test failed, Pending, Confirmed, Test failed since last DTC clear, Test not completed during this operation cycle, Warning indicator requested ============6============== 481F8C Raw code: 481F8C ECU: TPMS Status: Test failed, Pending, Confirmed, Test failed since last DTC clear, Test not completed during this operation cycle, Warning indicator requested ============7============== 481F8D Raw code: 481F8D ECU: TPMS Status: Test failed, Pending, Confirmed, Test failed since last DTC clear, Test not completed during this operation cycle, Warning indicator requested ============8============== 481F8E Raw code: 481F8E ECU: TPMS Status: Test failed, Pending, Confirmed, Test failed since last DTC clear, Test not completed during this operation cycle, Warning indicator requested ============9============== B7F665 Raw code: B7F665 ECU: Dashboard/Instruments cluster[Archive (inactive)] Status: Confirmed ============10============== B7F30F Raw code: B7F30F ECU: Flexible bus interface Status: Warning indicator requested ============11============== B7F311 Raw code: B7F311 ECU: Flexible bus interface Status: Warning indicator requested ============12============== B7F313 Raw code: B7F313 ECU: Flexible bus interface Status: Warning indicator requested ============13============== B7F315 Raw code: B7F315 ECU: Flexible bus interface Status: Warning indicator requested ============14============== B7F316 Raw code: B7F316 ECU: Flexible bus interface Status: Warning indicator requested ============15============== B7F318 Raw code: B7F318 ECU: Flexible bus interface Status: Warning indicator requested ============16============== B7F319 Raw code: B7F319 ECU: Flexible bus interface Status: Warning indicator requested ============17============== B7F31A Raw code: B7F31A ECU: Flexible bus interface Status: Warning indicator requested ============18============== B7F322 Raw code: B7F322 ECU: Flexible bus interface Status: Warning indicator requested ============19============== B7F323 Raw code: B7F323 ECU: Flexible bus interface Status: Warning indicator requested ============20============== B7F8C6 Raw code: B7F8C6 ECU: Infotainment system[Archive (inactive)] Status: Test failed since last DTC clear, Test not completed during this operation cycle ============21============== E71448 Raw code: E71448 ECU: Climate/heater/Air conditioning Status: Pending, Confirmed, Test failed since last DTC clear My car has a stage 1 bootmod3 tune and a VRSF catless downpipe installed. The tune is set to deactivate the CEL from the downpipe. The TPMS codes state that all of the sensors are bad, but I believe it to be the RDC module, not the sensors. I've been having this issue for months. Besides from the TPMS, I have no idea what any of the codes mean. I started looking each one up individually, but i don't know which ones are just from having the car tuned, and which ones are pointing at actual issues. The reason I scanned the car in the first place was to figure out what set off the drivetrain malfunction warning, but there are a lot of codes. can someone please help me figure out which ones are related to the drivetrain malfunction, and possibly what else I should look out for based on the codes that came back? Any help is greatly appreciated, Thanks. |
