As memtioned above, I took the car in for the 3rd time for dreaded belt squeal. Dealer had it ready to go with the installed aftermarket Korean belt 24 hours later, but asked if they could keep it one more night to make sure there was no issue at start-up the next day - no problem! Picked it up yesterday and all is good so far!

While at the dealer I complained of brake pulsing so the dealer also REPLACED my front rotors and brake pads despite having another 22k mi to go (according to computer) on the existing pads.

I also complained about the mpg decrease since having the emissions recall performed (egr replacement and repgoram) and the SA stated everything appeared to be operating within in spec, but that they will document the problem and that perhaps BMW will investigate if they receive enough complaints - so for everyone else COMPLAIN if you are seeing similar results since having the EGR work performed. It sucks that I am now getting high teens mpg city.

The dreaded A/C squeal is back! I was picking up my car from service and the runner went to grab my car, which had been sitting in the sun, and BAM, the squeal was back. I actually did a double take to see if there were any other cars that could be making a noise, but was sorely dissapointed. I asked the runner if he pushed MAX AC and he said yes.

Make a long story short, I left the car for another week. This is my 3rd time in for the same issue......Im starting to think alot of the mechanics aren't competent. Luckily my SA was promoted to Manager so I will make sure to run any continuing issues by him.

I don't mean to bump such an old thread, but I believe I am having a separate problem. My "squeal" isn't really a "sqeal," it's more of a consistent chirping noise. It isn't present on cold startups, or any startups to be specific. It is only there when the fan for the AC is on low-medium. When the fan is completely off, it's silent, but it will also go away when the fan is on full blast. It doesn't seem to come from the engine compartment, but rather from somewhere behind the instrument cluster, under the dash. It is very loud and very annoying, and it will stay as long as the AC is on. Help.
