I never heard of a catless F series BMW without a CEL, it will keep popping up unless you disable the system with a tune.

I recently spoke to a tech at Dinan and he informed me that modern BMWs have 12 different checks dedicated just to emission fault detection. It was inevitable you would get a CEL.
This thread had people who used the defouler and worked long term with no CEL though, some reporting in at 2 months and 6 months, not all hope is lost for me, one guy reset it initially and CEL never came back, maybe that'll be me too?
