Why does my BMW M9 have a high-pitched noise while accelerating?

I recently purchased a BMW M9 and have noticed that while accelerating, there is a high-pitched noise coming from the engine. It's not a constant noise, but it occurs every time I press the gas pedal. Is this something I should be concerned about and how can I fix it?

It is important to address this issue as soon as possible. The high-pitched noise could indicate a problem with the engine or exhaust system. I suggest bringing your car to a certified BMW mechanic to diagnose and repair any potential issues.

I also experienced a similar noise in my BMW M9. After consulting with a mechanic, I learned that it was due to a faulty exhaust gasket. It's a relatively easy and inexpensive fix, but it's best to have a professional take a look.

I had a similar issue with my BMW M9 and it turned out to be a loose bolt on the exhaust system. I suggest checking all the bolts and tightening them if necessary. If the noise persists, it's best to have a mechanic check for any other potential causes.
