Okay hope everything is okay with you and the family, had to go through Katrina in 2005, it was devastating ... Keep me posted , I'm thinking about changing the ICV, I cleared the check engine light couple days ago, and it came back with " manf control vehicle speed, idle speed control auxiliary inputs" which was the same issue before, so im thinking ICV please correct me I I'm wrong !

40, I have been tempted to replace the idle valve too. But, I already hung one part on this thing that it didn't need because I THOUGHT I had seen enough evidence. Ain't doin that anymore. I want to be very sure before I buy any more pieces. What is that first code, MANF control vehicle speed? Don't recognize that one. You must have a good scanner, that sounds like a beamer code not generic. Have you gotten that one before?

I totally understand , specially no one wants to spend money on a part that's working fine , hmm yes I have had it couple time before, I would say in the last month but kept erasing it , the code number is p1500 , as much as I want to replace the ICV, when I took it out and cleaned it it didn't look that bad , had black dust on both ends but cleaned it and it was moving smoothly , my other concern is the throttle body .. I hope it's not the case tho..

I cleaned mine too. Same, seems to move freely. The one thing I noticed on it was that it had some scratching on the vanes. I don't know if this is normal or not, or if it would affect operation. I used to fix Volvos, I think they used the same IAC and I never had to replace one. It's been a while though and I was pretty green. I am still in touch with one of my old co workers still working on Volvos. I will call him and ask about this. It is the only abnormal looking thing I could see on the IAC. I'm ordering a set of micro files for cleaning electrical connectors today, they should be here next week and then I'll work on the wire harness. More soon.

okay sounds good, i was looking into the throttle body, some of our cars come with cable and some come electric, it depends on the year, i believe mine is electrical , new one would cost around $250, not sure if i wana go there yet, might go head and the ICV first, i will keep you guy posted ..

Have you cleaned the throttle body? I would for sure do that before buying one. I talked to my buddy about the ICV and those things hardly ever go bad and when they do there are obvious symptoms. Scratching on the vanes is normal, does not affect anything. I got my file set yesterday, gonna try to go after the wire harness this weekend with it. I'll post when I learn something new. I'm pretty sure your car is drive by wire (no cable).

I have the exact same problem as well.. slight pedal pressure brings it on, quickly after startup
I have my own thread on it.. I've replaced MAF and ICV with no change.. still get P1500/211 mechanical fault, jammed open.

...i didn't realize I was talking to the same guy. My bad hahaha. Bummer App blinds me
By the way, the bandaid for my issue (until I can get a real solution) is to unplug the MAF. I get limp mode every time with it plugged in, and never without it. Of course, startup is slightly rougher, and MPG tanks, but for me it keeps her going. This works because it gives your ECU an open-loop mapping, which has predetermined variables and does not utilize some sensors.

Thanks for joining in weste. Haven't learned anything new yet. Got a few things to try, but need time. I guess after Thanksgiving. We'll get there someday! Tough when you're short on $ and time.

I'm in the same boat. Hey, if you have any ideas on where to start, I would be interested in helping out the hunt! I honestly just ran out of solid ideas, haha.

OK. I am reviving this again. Had my ICV replaced today and throttle body looked at and within 15mins of driving the 3 dreaded lights came back on. So now I am really not sure what is going on. I did notice this though, during the Fall of 2012, this issue showed up. Winter came along and had no problems the entire winter. Now that it is Spring and the weather has warmed up consistently, the lights are back and I am in limp mode again. Can there be a reason why the outside temp could be affecting this??

If temperature affected it, my instinct tells me electrical.

Checked your transmission thermostat?

And check codes to see what temp the transmission is reportedly running at. Could be related...

lilbimmer! Good to hear from you. Electronics are very vulnerable to temperature at times. You may recall that I also replaced my throttle body to no good result. I think I drove like a week without a failure. But check this out: Recently had a chance to talk with a grizzled full blood German Beamer mechanic named Zigmund about this problem. He said to unplug the MAF and drive. I did that about 3 or 4 months ago, get ready.....NO FAILURES! Car runs like a scalded dog! If you do this be aware that you will lose cruise control and there may be reduced fuel mileage because as I understand it, this puts the car in a permanantly richer state. Ziggy stopped short of saying the MAF is the problem because he wanted me to bring the car to him so he could scan it and such. Can't do that, can't afford Ziggy. Other than the above there seems to be NO down side to this fix.
I want my cruise back so I'm going to try and figure out how to fool these pesky computers into giving it back. Also want to find the REAL problem and plug MAF back in.

What's good silvercar? Funny you should mention the MAF as I asked the mechanic who worked on my car last week what his thoughts were about removing it. He was kind of weary of doing so. Like I mentioned in this post or another, I was fooling with the MAF one day and did not see the lights for weeks. So did you take the entire box off or can the plastic piece that connects to the air filter come off? I might try this this weekend.

To the other comments, the wiring has come up as a possible issue as well.

How do I check this using the BMW 1.4.0 Scanner?
