Increased emissions warning!?!

AlpineMsix · 6th October 2009, 01:23

So i got the increased emissions warning after starting up my car today..

Made an appt with the dealership to get it checked out...

Now im just worried because my software and my intake system are both Dinan so thats okay

But my exhaust system is ASR GEN2.... I really hope they dont blame it on that... could those be related issues?(Even though I have had the exhaust on for over 12k miles.....

I really hope they dont blame it on my exhaust!

Had the same thing over the summer, i was afraid they were gonna blame it on the eisenmann but it ended up being that a part needed to be replaced. I dont remember exactly what it was but definitely head over to your dealer, i remember my service advisor saying it was a good thing i wasn't afraid to bring it in.

If they blame it on the exhaust, they are just plain BS'ing you. It is impossible for our exhaust or any other manufacturer's, for that matter, to cause an increased emissions warning light. Usually this is caused by a malfunction of one of the many devices that have a direct correlation with fuel control and timing. The dealer should easily be able to figure this out once they scan the car.

Would this cause loss of power?

the emissions warning was due to a failed oxygen sensor

I also had the same problem but would this cause a loss of power.

Happened to me too, I was driving to Florida when it came up. Didn't slow the car down or anything. It was weird, it showed up then next morning when i turned the car off it went away, and came back up when I got back to NYC.
I took it to the dealer and the SA told me that the intake was just loose.

Yes Sir! This would cause a loss I power because the AFR would not be correct. Can even cause damage to the engine.

And my light just came back on too. It went away after a week and it just came back today. I have removed the charcoal filters a while back otherwise it is a stock 2006 m5. Looking at history from the dealer at 50k miles my car had the increased emission light on that was diagnosed to be an internal leak in oil pump and hose. Pump and upper oil line was replaced.And the next line says Replaced leaking Vanos high pressure hose and pump.
I have just noticed my pax side vanos is clicking louder than usual. Not sure if it is the one that was worked on...
Coincidence or not i had this sudden drop in oil level from 0.6 to 0.0l. To be on the safe side i added .7l and the new total is 1.0l ????
Another think that is hard to understand is that at 56k miles both cats were replaced with new ones?

But i will start by checking for a loose intake...
