questions again!
nothing worrying but when i first start up and for the first minute or so there is something whirring, like a pump (air-con off) which then shuts down. if you rev to about 3k rpm it starts up again for a few seconds.
i though it could be this electic water pump thing which cools the turbo after the engine stops, does it pump oil up too to protect the turbo when cold?
any suggestions?
