There was no impact on the vibration. I haven't checked the plugs.

I've ordered an OBDII connector through Amazon and I'll turn my laptop or iphone into a code reader when that arrives. I'll let folk know what I find.
Needs to be able to read BMW codes. BMWhat is a good choice.

Quick update: The wireless OBD2 connector finally arrived and I downloaded the trial version of BMWhat. Both worked perfectly first time. BMWhat picked up a few codes but they were all of the 'random noise' variety. There were no ECU codes. That was a relief but doesn't help diagnose the vibration.

I was operating under the assumption that the dirty plugs and vibration were connected given that they started at the same time but it turns out they weren't. Around the same time that I started this thread, I found a thread on dirty plugs where the issue was that the plugs hadn't been torqued fully. With nothing to lose, I pulled the plugs, cleaned them and put them back in, giving them an extra quarter turn. My torque wrench doesn't go low enough to be useful. I pulled one plug at the weekend and it was cleaner than when I reinstalled it. Put it down to basic human error. I've changed plenty of plugs in the past (not in BMWs) and proper torquing has never been as critical.

Now I'm in the same boat as everyone else with the vibration at idle and no other symptoms.

What is the torque spec for the plugs ?

Generally speaking, once you find a vacuum leak, and still have a problem, look for the other vacuum leak.
A vacuum leak will often not show a code, because enough air is flowing thru the MAF to be in a normal range, and the O2 Sensors adjust to a somewhat normal mixture, but not exactly.
Physically examine each boot carefully, with the small bellows off the elbow near the throttle body being a common culprit. Also remove the cabin air box and find the small vac hose under the back of the manifold.
With the air filter box and MAF Removed, find a rubber hose leading up and fwd from the Dipstick tube. Be sure that is intact.
While there, also remove the DISA valve and inspect that.
Nothing difficult anywhere along here, should take less than an hr to do it all, and gives opportunity to check around

Yep. Have two of those, a M60 with a Supercharger, an Xterra, an old Z and a flock of motorcycles.
The principals of all are the same. I've been a mechanic on all sorts of machines since High School (1983) and learned along the way to look it over for mechanical issues first. Fix all that then check pressures, then go for electronics.
Just like going to the Dr. They give you a good head to toe exam, then a set of vital signs, then they ask whats hurting.

Mein Auto: BMW 525i
The kids' soccer season is coming to an end so I've got a little bit of time to continue troubleshooting the rough idle. At the weekend, I decided it was time to try cleaning the idle control valve. I removed all of the air intake assembly up to and including the throttle body. That's when it got weird. I couldn't find an ICV. I removed half of the cabin filter assembly to see if it was hiding back there but couldn't find anything. I noticed that the throttle body is 'drive by wire' so, at least in theory, you could use the ECU to control the idle via the throttle rather than relying on the ICV. Can anyone tell me if this is how BMW does it with the N52?

I looked online for replacement ICVs for this engine and found nothing, which would indicate that it doesn't exist or I'm just bad at looking.

This is the 525i version of the 2007 model, so it has the single stage intake manifold (i.e. no DISA).

lol, this ain't a Honda....

Google valvetronic and you'll see how BMW controls the "throttle" on that engine. Def. no ICV.

The throttle body doesn't even do most of the work--say thank you BMW engineering

Sometimes, I wish it had just a little in common with a Honda :-). The filter on the windshield wiper pump blocked last week and I cleaned it at the weekend. On my wife's Honda or my son's Nissan, it would have taken 5 minutes. I had to remove a wheel and pry back the inner shield to get to the pump. Still, it is a lot more fun to drive than the Honda or Nissan.

Thanks. I learn a little bit every time I look under the hood of this car.

just thought Id mention that I had a crazy idle every once in a while at start up when it was hot and on cold starts. After changing out my valve cover gaskets it seemed to stop doing this, haven't noticed it happening lately. So its possible that a vacume leak from the valve cover gaskets can cause a rough idle .. Due to loss of vacume

Set idle with DIS.INPA is only for trouble shooting and will revert back at next start.Classic symptoms of worn intermittent levers or eccentric shaft or both.If you have INPA you can temporarily set you idle valve lift from .3 mm to .8mm.Do this and see if idle improves.If it does you have worn parts.Lots on this issue on earlier valvetronic models.BMW did an SIB but only on the n62.Ive seen it on the other forums across the engine range .Any valvetronic engine.Increasing idle speed will smooth it out for awhile,until the offending intermediate lever wears a new spot on the eccentric shaft.

On the N62 engine you can disconnect the VANOS solenoids and it will disable VANOS & Valvetronics. This reverts it back to using the regular throttle body and sets the valves all the way open like most engines.

I assume this would work on the N52 engine as well and would be easy enough to try.

Can also unplug the valvetronic motor,this will also put system in fail safe .If the intermediate lever is the issue the engine could still have rough idle at max lift??

Costco fuel bashing is not necessary. It's a top tier fuel and as such resides in the same territory as Chevron and Shell. I run Techron one fill up prior to a synthetic oil change, which is usually around 5k. I use Mobil1 0W-40 and Mann filters. In addition I add 2 oz of Marvel Mystery Oil and 2 oz of Sta-Bil to every 5 gallons of fuel that goes into the tank if my 2009 528ix. I have used this elixir for years in all of my vehicles that include BMW, MB, Acura, Saab, GMC, Volkswagen, Triumph, Volvo and Chevrolet. I also add it to all of my gas powered toys and tools including outboard motors and commercial lawn mowers. I have never had a fouling issue with injectors, spark plugs or carbs. It takes some effort to be diligent but well worth it.

I don't see how that would work. It seems that if you just unplugged the valvetronics motor, there would be no way for the computer to open the valves all the way to then use the throttle body, so I don't quite get that

The problem is slight difference between valve openings on different cylinders due to wear on the intermediate levers/eccentric shafts. When the valves are all the way open the difference between them is a very tiny percentage of the overall opening and thus not that big a deal

When they're closer to (or at) minimum lift at .3mm or whatever it is, a small variance is a much bigger issue

Your right ,valvetronic motor would sit at whatever position it was unplugged.
