OBD Reading interpretation

[Ruben]

My 2010 BMW 116i misfires and engine check light on the dash is on.

It provides the following OBD reading:

2B68 Air mass flow, plausibility
2FEF Thermal oil level sensor
2775 Combustion misfire, cylinder 3

Any advise on how to resolve the misfire.

Appreciated.

Hi Ruben....welcome to the Forum

Not entirely sure how these faults are related to one particular problem area....am thinking you may have separate issues there which will need looking at one at a time.

I would probably start with the Oil Level Sensor and then maybe the AMM next?

Let us know what you find

Morning Ruben

My 10 peneth for what it's worth

2B68 Air mass flow, plausibility.         This fault reading can be caused by a dirty (oily) Mass Airflow unit or a old clogged air filter check and clean/replace. I would start with the simple filter change.(Would I think cause random misfire and lack of power)
2FEF Thermal oil level sensor             Fairly common fault caused by a number of things Dirty connector or sensor failure (normally just a recorded fault no lights on the dash)
2775 Combustion misfire, cylinder 3 As cylinder 3 is nominated as the culprit Spark plug failure, coil pack failure are the suspects in my opinion. I would start by checking the loom to the connector at the coil pack, it's not unknown for them to chafe and short. If the loom is OK then simplest is the coil pack swap it to one of the other cylinders if the misfire moves that's your fault. If the misfire stays at cylinder 3 it will most likely be the spark plug..

Hope this helps
