[QUOTE=n8ronj;25892147]On the print out I got from the collision shop it said:
ECM 1.253400 Swirl Flap Actuator Open Too Wide

SCR 1.8051B5 Return Pump: Taught-In Volume Outside the Permitted Range



n8ronj.... curious if you resolved the SCR 1.8051B5 and what was the cause? I have a 2015 328d 65K miles and just found the code present this weekend. Not throwing a CEL (yet). All of the codes below showed up at the same time over the past week and still no CEL.

8051B5: Return pump, learned volume outside the permissible range
(DFC_SCRPODVolLrnBFP

I am also getting:
26F500: DeNOx system, efficiency: efficiency too low in range 1
26F600: DeNOx system, efficiency: efficiency too low in range 2
273600: Exhaust gas recirculation actuator position, long-term drift: position deviation too
high (current / new condition)

26F500 & 26F600 look up to be the NOx sensors
