Turbo flutter

[benali]

Just had the oil and filters changed. Now noticing a strange flutter noise from the airbox which I'm pretty sure wasn't there before, exactly the same as this:

Garage told me not worry, its just breathing differently with a clean filter.
Its got me a bit worried though, is it a sign of a more serious problem lurking around the corner?

That is actually my video! hehe

It done this with a cone air filter, but took it off the next day... It made my ECU pop an error.... Overboost..

Check if the garage tightened the airbox properlu, and the MAF itself

(i) The duct that links the blue circled air inlet behind the headlight to the airbox, through the inner wing.  It's the clean looking pipe visible just behind where the indicator would sit.

(ii) There is an air filter fitted, and that it is fitted properly (3 screws to remove airbox cover.
(ii) If they've done the diesel filter they may also have removed the turbo air pipe between the intercooler and the manifold for access, and not refitted it properly. If they'd done that though I would expect it to go into limp mode if you tried to drive it.Visible to the left of the diesel filter here.

If you can get someone to rev the engine while you listen with the bonnet up you may get a better idea where the noise is coming from.
