Actuators are about 1K each and 700 labor, have both replaced at same time along with the O2 sensors

I also have the increased emissions show up on my 2011 e93 M3 today.

274A, 2742, 2B59, 273E, 2748

I have all five of these codes show up. I am wondering If my issue is the same. with low voltage and need a new battery

Bumping an old thread.


I got codes P2430 and P2432 bank 1.
Air system air flow/pressure sensor circuit

Anyone with experience of these specific codes?

02? Secondary air pump?

I just received the dreaded increased emissions today on my 2013 E93 M3 (65k miles).

Sounds like a mixed bag in this thread between o2 sensors, actuators, valves, bad battery, and gas.

Is there any definitive resolution that is a sure thing or it is all dependent on pulling the codes unique to the vehicle?
