Hi, I have a 2011 1.5 dci.

There's an inconsistent loud screeching noise coming from around the throttle body area in the engine bay. It only occurs when rpm goes above around 2k, and is most common when I have just lifted off the accelerator. The car drives fine otherwise.

Has anyone experienced this before? At first I thought it might be an air leak, but I have checked all hoses and they appear to be fine. Could it be the throttle body itself?

Here's a photo to be clear about where I hear the noise from:
