PLASE HELP-Wastegate errors
Hello, I am not a mechanic so am looking for help with the error codes here. It looks like I have a wastegate issue with Turbo(s) and valve/CAM issue. This is a 2018 M550i with 70,000 miles. Anyone know where I can determine if there are additional dealer actions for these issues? Thank to for any help at all!
I have attached images of the scanner screen. Main errors are: 12343A 120908 123525 etc...Many more in images |

That Camshaft Jammed error code does not sound good at all. Are you tuned/modded? With so many codes, its hard for someone to narrow it down. Your best bet would be to take it to a reputable indie shop and have them properly diagnose it.

If you're handy, open up your Integrated Supply Module and pull all of the plugs. Check the connectors for coolant residue, or even melting. If you can, also check the thermostat for any leaks. Heck, while you're under the hood, just look for coolant leaks, anyway.
Last year, my thermostat cracked, causing a coolant leak to travel up the wiring harness from the thermostat into the Integrated Supply Module, which then caused a short. My initial symptom was a code for one of the O2 Sensors, then within 2 days a Drivetrain Malfunction which prevented the car from starting. The short even caused the connector in the Integrated Supply Module that sends power to the O2 sensor to melt. Dealer ended up replacing the entire wiring harness, thermostat, O2 sensor, Integrated Supply Module, and DME for bank 1. My SA for that repair said that this was a known possible issue. Granted, I trust him about as far as I can throw him....but given the electrical faults you're seeing, it could be possible your symptoms are just different symptoms for a similar cause. If you get this diagnosed, please post back with your/your shop's findings.
