CDTi - air release noise on switch off

[bluesky]

On switching off the engine of my CDTI 131 there is noise of a release of air pressure from the engine. Is this normal noise from the Turbo or something more sinister?:bowdown:

If it emanates from the dashboard area it is probably just the usual noise the Air Con makes.

Thank you Derek. The noise does come from the dashboard. That's a weight off my mind.

If it's coming from the aircon system, I'd check that the slow speed fan is working. These noises are a sign that the condenser cooling is not right.
