Bad mass airflow sensor
Can a faulty mass airflow sensor cause drivetrain malfunction to display?

To answer your question; yes, it can. I had a couple o2 sensors go bad at the end of the exhaust manifold that would spring up limp home mode and a "drivetrain malfunction" every time I would give it the beans. Anything that alters the vehicles ability to calculate fuel to air ratio on the fly is going to cause a malfunction due to the fact it starts guesstimating when a sensor goes bad and the system cannot guess the mix faster than you can step on the gas. Would recommend pulling codes to make sure.

I am having drivetrain malfunction issues on my 2013 528i xdrive.
The codes I am getting are:11A002, 11AC02, 213601, 108A01, P0015, and P0087. The car has a brand new engine, turbo, air filter, tmap, fuel pressure sensor, lpfp, hpfp, spark plugs, and coils. I have also cleaned the MAF. I am lost on what to do next. Please... Please... provide assistance on next steps to take. Thanks in advanced. |

Prior to the engine & turbo being replaced there was 117892 miles on car. Since leaving the shop last year (12/5/2018) I put only 448 miles on car. |

Forbes if the engine (wether it be a brand new engine or a remanufactured engine) directly from BMW and they did the work to replace it, they warranty their parts for 2 years after the date you drive it off the lot. Given the fact you've replaced most everything in that car more recently, I would bring it into them and have them take a look at it. They'll honor their warranty if those parts are in fact causing the problem.

I will schedule an appointment for tomorrow to get it looked at. Thank you so much for the feedback. I will keep posted on what they say. Drove it to work yesterday and it drove fairly well, however I am still not getting enough boost/power. [IMG][/IMG] I posted some of my most recent fault codes. |
