Hoooo sound
Posted: Wed Oct 14, 2026 10:19 pm
Hi all my first post and I’m after some help please.
Scirocco 2009 1.4 160bhp. As I’m driving there’s a quiet hoooo sound lasting around a second and at the same time there’s power drop or it actually feels like a very quick dab on the brakes. As I said it only lasts around a second but it’s random and can happen at anytime, in a 10 mile drive it happens 3 or 4 times.
It’s more of a hoooo sound than a moo so I don’t think it’s the moo valve that people talk about.
Thanks all.
