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

mercredi 19 novembre 2014

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!
