What dealership? If it was Jessel I would question whether they actually did anything.

In my experience they are lying cheating D-bags.

BTW where in Van are you located? I have always wondered how my car would pull compared to a 330. All within the confines of law, of course. And obviously in a safe place...

Thinking that this might be related to another issue I cleaned my VANOS solenoids last night, MAF, and hoped that all would be fixed when I started her up this morning... To my dismay again, it was not. I had 2AAB and 2A99 fault codes stored, so that was why I thought maybe cleaning the solenoids would fix it

One more thing I'm thinking I could try is switching primary O2 locations just in case they were misplaced after installing headers, but wouldn't that in itself throw a lambda fault right away?

Thanks for everyone's input and experiences

I would take a look at the outside DISA valve to see if there's play in the flap. Those have been know to cause a surging idle.

I have noticed even after 300miles and cleaning my maf, adapt reset with Bav tool, reloading AA tune with G5 nothing help but just time. I currently have 800 miles and it finally went away. I was idling 900 instead of 600-700..
It was annoying as fluck...I will be buying a header soon but still unsure between AA,AFE,SS

He has indicated that he just has the stage 2 AA tune, I'm pretty sure.

pinoye90 I think you're probably right... last night and today I went out for a rip again, and I don't want to jinx anything, but so far it has been idling really nice with only minor, insignificant blips *FINGERS CROSSED* As for the headers, I really do like the fit and build quality of Active's- definitely recommend them.

I actually went to the BMW Store, on Burrard. Being the skeptical ass with OCD, I actually snuck into the service hangar after handing over my keys, found my car, and told the tech DON'T DO ANYTHING EXCEPT RESET ADAPTATIONS. Since then it seems like my car has done some re-adapting to the updated tune, because today my idle has smoothed out significantly. If it fixed it permanently, it's $100 well spent. Plus I loaded up on chocolate chip muffins in the lounge and got them to give my car a wash

I'm always down for a little (legal) spirited driving. I live in north van, u?

By AA i meant AA tune since that's usually what it means, my bad I have the money for the headers just standing by researching more details

Sounds good. Check this out for future GVA meets: http://www.e90post.com/forums/showth...er+meet&page=4

***UPDATE***
This problem hasn't gone away. In fact, in seems to have gotten worse, accentuated by a complete break-down on my way to work this morning. Car was running fine, then all of a sudden, when I come to a quick stop at a red light, the engine just SHUTS DOWN without so much as a sound. I am thinking "WTF?" and start it back up, throws a CEL, it is choking, misfiring, running rough as a whore, so after quickly pulling over, shut it off and get a tow to my indy. The code was the same as one I had last time I was misfiring on the highway when this whole idle issue started: 2a99 - exhaust camshaft correlation. Cylinder 6 was the one that misfired, and had pre-detonated, causing the spark plug to collapse in on itself. After checking all plug gaps, resetting the Vanos timing, the car started up and ran fine.

I picked up the car after work, and it's back to the way it was before, although I hesitate to say that it's fixed (my mechanic didn't replace anything, after all). Since I have cleaned my solenoids since the last time I had issues, and my idle is still inconsistent, and only settles temporarily at times, I'm worried that this is more than just a solenoids issue... camshaft bearing ledge worn?!? It seems to run the roughest when the car is on an incline/decline, or when coming to an abrupt stop, making me think this is an oil pressure/retention issue in the camshaft. Has anyone had experience with this? Should I just bite the bullet and get new solenoids?

I had a neighbor offer to buy my car the other day, and I never thought I'd say this, but I am now considering it, especially if the head needs to be replaced..

Clean and swap them first.

I did that already- one week ago. If it were a solenoid issue, wouldn't the code follow the faulty one, not remain the same?

Correct.

Well f*ck me then... Could this be an issue caused by my tune timing? I really don't want to go down the money sucking hole of VANOS actuator or camshaft replacement

I doubt it's the tune. How does the valvetronic sensor look?

[polskatomek]

Haven't looked into that yet. Need to work up the courage. Too busy right now to tackle that if it needs replacement..

Start with the easy cheap stuff first dude.

[polskatomek]

Thought I'd keep everyone apprised of my situation- it seems that after changing my spark plugs a couple weeks ago (NGK IridiumIX) my idle problem has been solved. I decided to give that a try since it was still running on original OEM ones. Been idling smoothly ever since. Technically, the BMW interval for spark plug change on the N52 motor is 100k miles/160k kms so I didn't initially didn't think of it, but of course, dirty plugs are known to cause idling issues! Still running AA's header tune and loving it
