Squeak
So my car has been making this squeak sound - for want of a better description - under no particular circumstances. Car is going into BMW tomorrow for a look but wondered if anyone here had any thoughts.
Please see attached sound recording. This was after a cold start in the morning just letting the engine settle and about 50 seconds later the noise happens. Times I notice the sound: - as the car slows to a stop (coasting and under braking) - depressing accelerator / brake / clutch pedals - releasing brake pedal - changing from comfort to sport mode - while accelerating - while changing gear - while idling from cold start - while idling during a drive ...I thought it was only happening on hot days once the engine had been given a good run in but it's not so consistent. Also happens more when in sport / sport+ than it does while in eco / comfort. It's sometimes really loud and I'm getting embarrassed that people turn around to look my way when that sound occurs now more than they did because of the burbling / crackles of this beautiful engine / exhaust. If I'm cruising through town between 20-30 mph then I'll hear it a lot. Wind the windows up and turn up the music at least stops me hearing it but I actually rather listen to the car...

It's the flaps in the exhaust. Mechanically the dealership are saying nothing is wrong so it's just a characteristic I'll have to live with. Yeah, like when I was told the hissing and crackles from the HK system was a characteristic of a high end car I'd have to live with. Feeling a little fobbed off...
