I don't think you will have a problem getting the EVAP monitor or the Secondary Air monitor to complete.......But as far as the O2 monitor and Catalyst monitor goes if your luck is like mine then it's not hopeful. I'm pretty disappointed myself.

If nothing comes up with bimmerlogger or INPA, I will be putting the stock manifold back on and loading the tune for just the 3-stage manifold. I have run out of patience, lost a sale on my car, and have lost multiple cars I wanted to buy.

Well that was driving after an hour.

So I'm not hopeful lol

I did the drive cycle many times, over 700 miles at least and couldnt get it to pass.....

Guess time to research and see what needs to be done to get the cycles complete. Have to be documentation somewhere.

Interesting. This is what I found:

Hi,I thought tunes just code out the o2 sensors,cause that's what's taking out? The evap and air pump are the car itself,you may have sensor problems,check your gas cap and related fuel lines up front,can you sent you ecu to aa to be checked over? Road test with resets don't take more than a hundred miles,I've reset mine on my e60 n52 and it goes into every monitor not ready,takes about 100 miles. Have you tried to contact another tuner on there opinion? If your changing your tune back to stock and still pulling codes,you have bad sensors,I'm on a 3si with no tune,and no codes,runs like a top! You should have no codes on a factory tune,you'll just carry it over and be in the situation your in now,try new 02 sensors,there funny if not operating correctly. Hope this helps

It's definitely possible to force the catalyst and O2 monitors to "ready", but I'm not AA and can't speak for them.

your 325i doesn't have an SAP monitor. I think that is only on the N51. I'm not even sure the N51 has SAP, but it has different emissions equipment than the N52s.

If you are selling the car, I'd just put the stock exhaust manifolds back on. headers aren't going to affect resale value, but not being able to pass an emissions test definitely will. You could make up the costs of going back to stock by selling the headers.

The N51 does have secondary air, but you are correct that I do not. That monitor for me is N/A on my scanner.

I just mainly don't want to have to remove the headers because I don't have a lot of free time to do it and don't want my car down for multiple days since I would have to do it after work at night.

I also really want to figure this out because I do not like to be easily defeated and am stubborn. I'm going to be making a final decision this week, but as of right now it looks like I will be reinstalling the OEM manifold.

INPA tell you anything?

unfortunately that is the price we pay for adding power to the car. I still have my old headers in case I ever want to go back . My car runs well ( knock on wood) and it def has more power but the other side of the coin will be when I go for emissions and the smell of the catless headers.

I added a highflow cat converter after the secondary cats which got rid of most of the smell , and I can make the car pass emissions for a fee

care to elaborate? Inquiring minds want to know.

AFE headers seem like a good option for you guys.

Been super busy so I haven't had a chance to install it yet. Going to do that tonight and see what I come up with.

UPDATE: Everything I could possibly think of and that has been suggested to me has been tried with zero results. For some reason my car just does not like the AA N52 catless header tune and will not pass inspection. I was really hoping that I would be able to figure this out for myself and for the sake of other forum members, but I have officially given up. I've been driving around for almost 2 months uninspected while receiving one ticket and multiple close calls its the end for me.

So before you install the AA N52 Headers think twice, because you could be part of the unlucky people like myself that will not be able to pass emissions for inspection. It is very dissapointing when you purchase a product, that is also not cheap, and it does not work properly. Anyone that has run into a similar situation as myself please feel free to comment.

I will be installing the OEM N52 manifold next week when it arrives and the headers will be going to TheAxiom so they will not be posted for sale unless he changes his mind.

Honestly, sorry I wasn't able to help you more. hassmaschine could have provided more guidance, but I understand you're at your breaking point.

My breaking point was reached a longgg time ago but you gave me a little hope so I kept trying. A little help is better than no help and there is only so much you can do remotely also. Thanks again!

My AA tune was nothing like as described, they promised issues/fixes after denying an issue existed for a long while (while others on here have had the same issue), and then were complete jackasses to me when I requested my money back. I went to Epic and the tune is awesome. I would never spend a dime with AA and will do my best to ensure nobody I know does either.

Sounds all too familiar my friend. At first they were helpful and would send me different tune files and request some data snapshots to look at it, but beyond that they did not do much. They cover themselves by saying it is for "off-road use only" and make sure they say it many times during your communication with them. I knew I wouldn't get my money back for the entire tune, but I asked to at least receive the $60 back for the O2 bypass since that was the part that did not work correctly and was promptly told no because it was for "off-road use only". I also will never be purchasing another Active Autowerke product after this experience because I got the feeling that they definitely know about this issue but are not doing anything to correct it since it may only affect 20% of customers. I am glad you commented and have a feeling we may see more people chime in with a similar problem.

Sorry to hear it didn't work out. Id say try Bpc,there doing wonders.

Well I planned to sell my car anyhow, otherwise I would give BPC a shot. My plan is to get either a 2009 or 2010 335i Xdrive, or an e46 m3 and a winter rat.

Who's BPC?
