Hi
Seeking some assistance with a really annoying high pitched whistling sound I am experiencing with my Tiguan mk2 2017 162tsi. It seems to occur most times whilst driving at lower speeds in particular. I took it to the dealer and they “couldn’t” replicate the problem.

Link to video with sound: - YouTube

I can’t isolate the sound very hard to pin point but could be water pump or pcv valve.

Thanks
