Sounds like a snake living on the rear axle...

Or some kind of pressure being slowly released... open the gas cap with the engine running and the hissing continued...

Recently replaced N80 valve but P0441 code has returned...

Its a 2.0T and Im preparing it to sell to my good friend.

Thank you

my mates s3 has done this since day 1 and now 39k miles on the original pump..
