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?

Got the code as well - increased emissions - 2013 E93 M3 80k miles - and went to read the codes today - and the car showed no "check engine" lights.

I don't drive the car much so it may be a low voltage issue with the battery.

Does anyone have the cost to repair the O2 sensor or even what they paid to get a new battery - which I do have a scanner - but not the one that can program a new battery...argh. Any insight would be helpful.

Did you get your M3 fixed - what was the final diagnosis - and if you choose can you include the approx cost to fix.

“Increased emissions” is not a code, it’s a whole category of issues. You need to scan the car with a bmw specific scan tool or you’ll just be throwing parts at it. Could be anything.

Could be a bad (loose) worn out gas cap.
