Whistling Sound and Shake @ Idle

I have read several posts that seem to touch on this subject but none of them come to conclusion, or the discussion will veer to a different topic, or end up not dealing with my cars equipment. So I thought I'd create a new post.

2007 328i:
I have noticed that my car will start making a whistling sound as it warms up. When I begin my comute to work (or anywhere) the car is fine. About 5 minutes into the drive I start noticing the whistle. RPM's go up the whistle subsides and as the RPM's come down the whistle is obvious. As driving continues, there manifests a constant whistle and when I come to a stop the engine shakes sitting at idle. If I turn the car off then start it back up, the issue resolves itself.

This issue is not consistent, but has become more prominent in the colder winter days that we have been having here in Oklahoma. I had been simply dismissing the matter, but today the service engine light came on. I have not had a chance to code the light. I'm not sure that the service light is related to the behaviour because the light has come on once before during the summer but turned off on it's own.

Got the code

Took the car to autozone to run the code. It returned P1553. They didn't have any BMW specific information on this code. However the Volkswagen definition is: Barometric/Manifold pressure signal ratio out of range. This also concurs with a description at this link. There was also another description at this link as being Engine Position System 'B' Performance (Bank 1). Anyone know what the implications may be in this situation.

BTW: After the guy got the code, I started the car back up and the SES light went off.

I searched the interwebs and couldn't find any help, I was going to post helpful info and then bubb rubb, but I couldn't find info, so you just get bubb rubb:





Note you prolly want to have a BMW dealer read the code, I read that generic OBD2 codes won't provide any info into the problem.

Rich,
Did you have any luck diagnosing the whistling sound? My car does the exact same thing and it's so embarrassing! In the drive through I can totally hear it, I turn the car off and on and voila the sound is gone... I want to get it fixed but I don't want to pay an arm and a leg...

I took the car in last monday and they pulled a code that indicates a cam shaft sensor. I have not had it replaced yet since the problem hasn't prevented me from driving. I can tell you that, in addition to the whistling, if I take the car on long highway trips (2 hours), when I exit the highway and come to a stop the car will stall. At that point I have to pull the key fob, put it back in, and the car starts no problem, drives good. I plan on taking it back in next month to have the work done.

Here are the codes that were indicated:
2A99 Crankshaft exhaust camshaft, correlation
2A82 VANOS intake

Whistling Sound and Shake @ idle

I'm having the exact same problem as OP.

Has anyone found a solution for this yet? Spent hours trying to replicate sound once i took it into the shop but of course it didn't make the whistle once i was there. This problem occurs often but not all the time. Maybe 20-25% of the time?

The high pitched whistle sounds like a tea kettle and it is very loud. I can easily hear it even with my windows up and music loud. Once the whistle kicks in the only way to rid of it is to turn off the car and start it back up. It makes the whistle while cruising as well as at a stop light.

I see people have checked their intake hoses but has anyone checked the intake manifold and the intake manifold gaskets? Or even the seals for your MAP sensor? Also throttle body gasket? On most cars I've worked with, those are the places where the whistling comes from.

I have this problem but the whistle seems to come out of the exhaust? It's only at idle.
