Any diy valvetronic intermediate lever post?
 

I've been looking for any post on diy intermediate lever and eccentric shaft replacement post. Does anyone know a link or post where I can get some info on how much is involved in doing this. I know most information I have found says this runs $1700-3K for a shop to do. I know I can do this myself and my wife's X5 needs them done. Im just looking for a little info from someone who's already done it.
Looking to get a few points on how to make things easier and what not to do. haha

In case no one has done it, I would also ask in an e60 forum and e65/66 since those had models that used your engine in some of them.

I've been surfing around those forums and its hard to search forums unless you sign into some of them. It seems like the N62 motors are getting to the age now where this is becoming more of an issue and I see more and more people posting the "cold start idle problems" We love our X5, I just want to make it right.
There are so many questions I have about all this, I just need someone who has been there done that and pick their brain.

Check my posts on a referral to a shop called Columbus Auto. The guy there (Ivo) has done levers on a few cars, but has seen it not solve the problem. When BMW does the levers, they do everything and that jacks the bill right up. There are some tests you can try to see if it's levers and maybe buy some time with the software adjust that BMW threw at them to get them through warranty. Otherwise, brace yourself for an "all in" experience if you want to do it right. Even though Ivo is up in Canada, he knows his stuff and will likely spare a few minutes to discuss with you. If you connect and he helps you out, let me know and I'll get him and the guys a round of coffee next time I'm there.

Cool, That's kinda what I was looking for. We plan on keeping this X5 for awhile, I'd rather fix it right and be done with it if it don't cost more than buying another used X5 "haha". Now looking back I should have talked her out of it when she wanted the 4.4 over the 3.0, but its her vehicle. I have a local guy who is coming over with software to check everything out before I do anything.

For search, not sure if you know, but I find the best way to search this site is typing the following string (minus the quotations) into a google search. Turns up best results for me. Use this for other sites that have less than desirable search engines too. Hope it helps.

Thanks for the tip, I've spent this week searching the interweb on this and haven't come up with much. So i figured I'd ask as a last effort.

If you have access to GT1 software, there is a test that you can run to see if it's the levers. Attached are the details on how to test if yours have issues and/or how to see if yours are part of the bad batch they had.

Slow&Steady, For completeness in this thread can you tell us why you suspect your intermediate levers need replacing. What symptoms are leading you there? Do you have any codes?

Im getting rough starts on cold mornings. When it does this we get a flashing check engine light and codes for multiple cylinders mis fires (don't have the codes in from of me) Its a 2005 X5 4.4 with 120K miles, production date 12/04. I have replaced everything that's replaceable. Plugs, O2's, CCV, cleaned throttle body, Maf ect. It don't show up anything being off on my carsoft software, I don't have the GT1 software yet but I'm buying it. I have a guy coming this weekend to check the tolerances on the valvetronic levers if he has time. I think that sums it up.
Im confident its the eccentric shafts and Intermediate levers.
