Check engine light after new dinan cold air intake
I installed a Dinan CAI on my 2015 m235 with no other mods except MPE. I bought the dinan intake because of all the reviews stating no CEL since I am not ready to install a tune. The CEL appeared on the second day after install. Car is running smoothly. The code was P0171 for running lean. Any ideas with what may be causing the error? I checked the connections and cant find an air leak. Could this be something that resolves in a couple days after the ECU adjust? If not I may remove it until the N55 dinan flash tune is released.

The light has not returned after clearing the code and tightening all the clamps and MAF sensor a little more. After contacting Dinan they said the long term fuel trim average adjustment in the m235 is around 15-18%. That is where my car is sitting now after several days of driving. The CEL usually triggers at 25%.
