    Strange 'Jet Engine' noise on first start up...

    Hey guys/gals

    Not sure if anyone has experienced a loud high pitched 'jet engine' sounding noise ocassionally on the S3 just after start-up?

    Any ideas what it may be be? It goes after a couple of minutes, as I'm selling the car very soon, wanna get it fixed before selling on.

    Any ideas gratefully received.....

    That'll be the Secondary Air Pump, it's just doing its job, it's nothing to be concerned about.

    It pumps air into the exhaust system during cold starts to heat up the cat quickly and get it working on those emissions.
