Limp mode and a bunch of fault codes after that - any thoughts?

[krx927]

My car went into limp mode last week when I was tracking. It started misfiring badly and displayed "your engine is operating under reduced power, it's safe to continue driving but have your car checked at BMW dealer soon". After I restarted the engine it was running with out an issue.

I diagnosed it with BMWhat and I got 14 fault codes.

Do you have any thoughts on the fault codes from my car?

Additional important info: when this happened I was almost with out the gas, there was less than 5l left in the tank. I could imagine that some of the codes are connected with this, but for sure not all...

List of codes I think are connected with low fuel:

Motor Control:
Engine / Motor

1. Fehler: :Misfiring cylinder with a cut-out / Misfire with cut-out cyl 1
Code: 2B35

2. Fehler: :Engine misfire cyl 2 with cut-out / Misfiring cylinder with cut-out 2
Code: 2B36

3. Fehler: :Misfire with cut-out cyl 3 / Throttle actuator / Misfiring cylinder with cut-out 3
Code: 2B37

4. Fehler: :Engine misfire cyl 4 with cut-out / Misfire with cut-out 4 cyl
Code: 2B38

5. Fehler: :Misfiring cylinder with cut-out 7 / Misfire with cut-out cyl 7 / DMTL Diagnostic Module Tank leakage diagnosis, system failure
Code: 2B3B

6. Fehler: :Misfiring cylinder with cut-out 8 / Misfire with cut-out 8 Cyl / DMTL Diagnostic Module Tank leakage diagnosis, system failure
Code: 2B3C

7. Fehler: :Misfires with cut-out 6 cyl / Throttle actuator / DV-abortion adjustment, because the environment / Misfire with cut-out 6 cyl / DMTL Diagnostic Module Tank leakage diagnosis, system failure
Code: 2B3A

8. Fehler: :Misfiring cylinder with cut-out 5 / DV-abortion adjustment, because the environment / Throttle actuator / Misfire with cut-out 5 Cyl
Code: 2B39

9. Fehler: :Misfires with several cut-out cyl / Lambda adaptation cylinder 4 / Misfire with cut-out several cyl
Code: 2B41

10. Fehler: :camshaft sensor / unknown fault code / Camshaft sensor fault master / Info tank empty at fault entry
Code: 27C1

List of codes I do not think are connected with low gas and look a bit scary to me:

11. Fehler: :Oxygen sensor before the cat / Heater for lambda probe front catalyst / Output O2 sensor heater before catalytic converter / Output stage heating probe before catalyst / DMTL pump / VANOS control socket bank 1 / Heating DMTL
Code: 271B

12. Fehler: :check at lower top / Mass air flow sensor / Security concept manager action
Code: 2B57

13. Fehler: :Testing of lower stop / check at lower top / Secondary air valve, control / Check to their bottom / Throttle valve actuator, check the lower block / Check to their bottom/throttle flap / Throttle - check lower stop / Security concept manager action
Code: 2796


ABS / DSC / Brake:
Dynamische Stabilitaets Kontrolle / DSC

14. Fehler: Rear right direction detection / Valve HSV1 / Valve UPS1
Code: 5DC6

Any thoughts on the issues I might have?

The car has around 23000 miles and it is 2011. I took it to the track around 8 times until now.

Thanks!

That's a lot of codes. Take it to the dealer and have them check it out.

I am scheduled next Thursday. I was just wondering if anybody has an idea...

O2 sensor, throttle actuator, spark plugs

Let's see if you are correct: I take it to the dealer next Thursday.

Good that it is in warranty!

Some feedback after the visit of the garage. Basically they cleared the fault codes and they did not come back so they end up doing nothing...

I will monitor the codes with BMWhat and see what happens.

Low fuel could have caused the misfires. I can't run my e46 below 1/3 tank on track because of this.

I will also avoid it in the future...
