Hi All,
Was hoping someone could help me with a similar problem. On my e92 m3, when accelerating very gently (between 1-2k RPM, I hear this little jingle sound that is coming from underneath the car, almost underneath the drivers seat. The sound can be heard on the video posted below at around 10 seconds in (you have to listen carefully to catch it). It literally sounds like a little tambourine is being shaken and I have to drive with the windows down to hear it.
I did alot of reading around on this and it seems to me like there are several potential culprits: donut gasket that connect some exhaust pipes, a bracket that's loose, a mounting thats loose, heat shield (though my mechanic confirmed no issues with this).
The cars performance is generally ok, a little bit sluggish at times but I'm not a fast driver (lots of speed restrictions where I live).
I'd be very grateful if anyone can advise.
Thank you.
