Installed AFE MAGNUM Cold air intake in Early October - I had absolutely no issues until last week when I got a Check Engine Light - It was a pretty generic code so we cleared it - game back on again this week - I have a great BMW service department. They are going to return the car to the stock CAI and we will run it for a week to see. The initial thought is that it might have something to do with outside temp. It has gotten a lot colder here in NH and as cold air is much denser than warm they may be a issue with the increased air flow which is triggering a code. I will notify AFE this morning since I believe mine was the first one on a 2018 M240I x drive.
If anyone has seen this issue on a 2107 M240 please post here. This CEL does not appear to cause any performance issues just a pain looking at the little yellow engine.
