Hello group - my 2012 R60-S/N18-turbo just threw a bunch of non-standard hex codes (to me; e.g. no P-codes): My BMW+Mini reader shows 2EFE and 2EFF "electric fan" codes, plus 2F01 and 2EEC inlet and outlet 'plausibility' codes ?!?!

I'm a decent diagnostician (have had Bimmers for years - so it's required...grin), but I'm struggling where-to-start? 'Seems a temperature sensor issue, and IATs/thermistors are usually easy to check: Googling on it's p/n (13628519445) suggests that it's in the charge pipe - - does that seems right, folks? Any inputs are very much welcomed!

 

A google search shows 2EFE generally seems to mean cooling fan related, but also in some instances misfire related, depending on the computer. Mayb post the brief description next to each code if one is displayed on the scanner. I know the Schwaben scanner does that. You might also consider posting the cars symptoms that go along with the codes.

 

*There's the rub; really no discernable issues. It might be a tad slower to warm up to even idle, but after a minute or so - smooth idle as always. No other obvious performance or mileage-loss artifacts. The brief descriptions that I provided were from extensive googling of the codes, beyond what my BMW scanner shows... Thx!
