Hey Folks,
Please help me diagnose what the noise in my R32 MK4 is!
The high pitch whine/ noise in the video (below) occurs when I take my foot off the accelerator (usually happens when I'm in 3rd or higher) and coast. Doesn't always happen and seems to occur once I've been driving around for 5-10mins+.
This may not be accurate but it seems to occur between 20 and 30,000 RPM and sounds like it's originating from the passenger/nearside of the car though I'm not 100%.
I've taken it to VW and they reckon it's a vacuum leak from the engine, however,
