I'm encountering the same problem. Our SES code indicated 2 codes according to the ODBII scanner (P1419 & P1093 from Advanced Auto Parts). After taking it to the dealer, they indicated that it had two faults but didnt indicate the exact codes, the service order showed the following:
(1.) O2 Sensor Fault - Suggested replacing the Intake Boot since it was torn.
[Elbow Tube 13-54-1-440-102]
(2.) Mass Air No Signal - Suggested replacing the following:
[Secondary Air Filter, Non Return Air Valve, & Air Mass Meter]
(11-72-7-534-722, 11-72-7-553-067, & 11-72-1-438-814)
My question is, what are the chances that the SES light will still be on despite replacing these items. After paying $200 for BMW to diagnose the SES light, I wasnt informed about whether or not the MAF Sensor needs to be replaced [Hot Film Air Mass Meter 13-62-7-567-451. The Hot Film Sensor sits between the main Air Filter and the intake Elbow Tube.
The advisor indicated that the Hot Film Sensor would not cause the O2 Sensor to Fault. Do you think that $200 is too much for a diagnosis that left room for plenty of things that could be causing the SES light to come on?
