Strange whistle

Post by delroyx » Sat Mar 11, 2023 7:21 pm

Had a strange whistling noise on start up today. It went away fairly quickly but sounded like the noise in this vid..

Anyone else had this? No warning lights.

Any ideas on the part & number of the offending part & how easy it is to replace?

I pulled the rear RS carbon cover off. It looked quite different to the video I posted under there. I didn't look too closely as I didn't have time or my phone to hand. I'm guessing the video shows a 4.2L not from a B7?
