After 6 months of dealing with this "Increased Emissions" off and on I can say this issue was finally solved with a new "low fuel pressure sensor (and required adaptor since the design changed)". Problem solved.
BTW...The dealer threw a pre-cat O2 sensor at this issue with no effect. The low fuel pressure sensor (which I led them to after reading tons of posts here) was the culprit.

TBA replacment
Yes, do them both. About the same labor as doing one, and it's only a matter of time,,, (1 week in my case).

Agreed, I did both at the same time - about 52K miles.

Hey Guys,
I posted up that after storing the car shortly after getting it, I was getting the increased emissions error on the dash. After driving it for a while, it went away. Then, when I had battery issues, it came back. Again, I changed the battery and it went away. Anyways, more recently, I got the increased emissions again. I had filled up at an ESSO station near me and got the error message. I didn't know what was going on, but, I was going to take it to my local indy shop to have it checked out. Well, after about 3/4 of a tank, I filled it up with V POWER 91 Octane from Shell and the error went away. Yay. Well, shortly after that, the real problems started. I was downtown in early October and I was on my way home when the dash lit up with an increased emissions AND reduced engine output with the redline drop to 4500, rough running and all that. I shut off the car and it reset. It happened a number of times and I took it to my indy shop. They did an injector flush but that didn't solve the problem. After a further investigation of the codes, they saw a 2B59 (Coolant Thermostat). I had the thermostat replaced today. Fingers crossed that it the last of the engine fault codes (at least until the throttle actuator or the ICV goes). DrC

I had the dreaded "increased emissions" code about two months ago. After popping in the OBD2 in? It turned out to be the "low fuel pressure sensor" and i was relieved that it wasn't something far worse($$$). It was such a easy fix! Just remove the air box, and it's right in front of you. If you have small hands? You can probably do it with out removing the air box.

My 2008 with 71k miles just had the same issue. I typically only drive it on weekends and have been getting the battery discharge warnings, but I've been hesitant to replace the battery since it goes away once I drive the car for a bit.
I retrieved the CC ID 31 code by holding the stalk button down, but I'm assuming this doesn't narrow it down to anything. I'm not under warranty, so I'm not too eager to pay a tech to look at it immediately based on the experiences above. I also don't want them to do guesswork on parts replacement if it's just caused by a weak battery.

If we're talking about idle control valve, there is a service bulletin for it and you could get it replaced at your dealer for free without having warranty.

increased emissions problem - my turn
I just got the increased emissions warning light problem this week. I was driving at 70 on hwy, then wham, massive reduction in power...WTF? Increased emissions lights up, then the yellow engine malfunction icon pops up, but virtually no power - but engine was still running. Pull over, turn off, and back on....all good. Drive to next exit just fine. Then got back on and punched it and it happened again. Restarted and drove fine. Problem recurred a couple of times. Drove to dealer today, they say it is the Vacuum Pump. I hope this is the last of it. SA said this is unusual. My car is '12 coupe 6MT with 15k miles on it (delivery date dec 2011) and is uber clean. I asked what it might cost if not under warrantee and the guy said $2500 to 3000 (Pump over $2k) In case this is wrong, he just guessed but that is a sobering amount of $$ for what may be an ancillary part. I will update when I get it back. BTW, other than oil changes and tires this is the only issue the car has ever had.

My bank 1 finally went out at 175k miles so I just replaced both.

I'm getting code P0050 "H02S Heater Control Circuit (Bank 2 Sensor 1)"
Figured doing the obvious and replacing the driver side (Bank 2) pre-cat wide band (sensor 1) would fix the issue. Wrong. Car seems to run better post install but still throwing a CEL - Increased Emissions. Not sure how to trouble shoot now, as its acting like I never replaced the sensor. Suggestions welcome! -- car is a 2009 e92 dct with 112k. Runs well other than this, need to get it inspected soon!! |

Hi all,
I have a 2010 M3 with 28k miles. The increased emissions light appeared and stayed on for 5 days then magically went away. I did no notice some hesitation during acceleration but the car was drivable. I have EZ care so I took into the dealer and they found a bad O2 sensor which was replaced under warranty. I also had a flaky power door actuator which was replaced. Total bill was $1200 (but I paid $50 deductible only). Anyway, here's where it gets more interesting. They claim that the codes will be still be in the computer for "hundreds of miles" and I have a state inspection due this month which I will fail, they claim, because the codes are still in the system even though the idiot light is gone. They wanted $75 to clear them and claimed EZ care won't pay for it. Is there truth to this? I pressed them to indicate how long it takes to clear the codes and they gave me a wishy washy answer of 150 miles. Is this accurate? Can I clear them some other way easily? |

I too have run into this problem. The car lights come on saying increased emissions and basically shuts down the car where it will not drive over 40 mph. The BMW of Mobile Alabama had my car for almost a month. This is what all they did to rectify situation before replacing the EDM on the 8/80,000 warranty. Replaced was ]Both front and back O2 sensors and both actuators. They kept getting bank 1 or bank 2 message when the swapped them out so the ended up replacing both. Now keep in mind without any warranty on these parts it would have cost $1700 for each actuator had I gone to BMW Galleria in Diberville MS ( close to my house but I will never ever take a car to that dealership again. Its the first BMW dealership to open in over 23 years and the owner does not deserve that dealership. Hew is a stuck up snob who caters to his friends and family.
Anyhow, Becky in Mobile is wonderful. She managed to keep my bill low and made sure it was fixed before giving car back to me. |
