Apparently someone had installed engine software from the X5 M50d and X6 M50d vehicles which use the AdBlue exhaust purification technology onto the M550d and 750d. This causes some N0x emissions violations, but only affects a small portion of the vehicles unlike what we've seen with Dieselgate and the issues also seen by Mercedes.

Munich. The BMW Group has found in internal tests that a correctly developed software was assigned to some unsuitable model versions by mistake. As a result, the BMW Group informed the responsible authorities immediately. The corresponding software has been developed correctly for vehicles with a combination system of SCR and NOx storage catalytic converter.
However, this software was mistakenly used in model versions whose active exhaust aftertreatment takes place exclusively via a NOx storage catalytic converter. These models were equipped with the correct software at the time of their initial registration at the start of production in 2012.
Therefore, the BMW Group plans to recall 11,700 vehicles. Corrected software will be provided for these vehicles after approval by the relevant authorities.
Affected are niche engines of the already expired model generation of the BMW 5 Series and 7 Series from the years of construction from 2012 to 2017 with the high-performance diesel engine N57B30S1 with three turbochargers. In detail, these are:
BMW M550d xDrive Sedan (production 03 / 2012-10 / 2016)
BMW M550d xDrive Touring (production 03 / 2012-02 / 2017)
BMW 750d xDrive (production 07 / 2012-06 / 2015)
BMW 750Ld xDrive (production 07 / 2012-06 / 2015)
All further steps are carried out in close coordination with the responsible authorities.

Yup ... though some journalists have used lots of words to imply this is a diesel conspiracy.

Yeah, I tried to cut through that and make it more accurate. I am impressed, BMW has managed to produce their vehicles and not have these emissions issues.
