1997 VW Passat TDi 110 "Psssh" - Wee Willie Winkie
I've got a funny noise eminating from my Passat!

Under hardish acceleration in any gear, from 2000 to 3000 rpm I get a loud sound which is best described as "psssssssshhhhhh". It sounds like a load of air escaping - but performance isn't impaired, apart from a very slight hesitancy. It sounds like it's coming from the left hand side of the engine (as I look at the bonnet from the drivers seat)

Any ideas guys and gals?

Cheers,

DB

Check the security of the hose attachment on the top of the turbocharger, the big prominent pipe that comes over the top from the intercooler.

Mine blew off completely once and left me totally turbo-less. I can see how a leak would hiss quite a bit...
