engine bay noise

Any one help on this one.
Hi all - Captiva's just had its first10,000 ml service its a 61 plate 2.2 lt. When the air temp outside is warm I get a strange gurgly sound when lifting the accelerator of and changing gear (maual) took to the dealership and it didn't make the noise, (the air temp was 12 degrees) yesterday it had been sitting inthe sun all day temp about 21d and straight away there is a noise "rattle" when lifting the accelerator pedal while chamging gearit continues and doesn't go away, looked at some other forums seems they call this a chickening sound, sounds daft but anyways the dealer (main) couldn't find anything, told me when its does it again take out to them.
Also was checking on some entries on this forum re the std radio/cd, boy is it rubbish, the blue tooth is sub std and the reception in Aberdeenshire is shocking, will be up grading..thanks Paul

Mine does this sometimes too, not too sure if it's just in warm weather though, a Vauxhall service engineer told me it's the recirculating turbo dump valve several years ago. No issues with the radio on my '07 Captiva but I don't have bluetooth.

Not sure about your gurgling noise as not experienced it myself on the Captiva, but I did have a same gurgle on my previous S-Type Jag and found it to be air locks in the air con. As it had a complex climate control system, there are many valves to allow climate zones in the car, and the bubbles (air locks) made a gurgling noise but only when the car engine was switched off and the air con would be off and the bubbles would 'settle'. Never got it fixed, but as told it was a simple bleeding and re-gassing of the system.

As for you radio reception, it isn't the radio before you go through an upgrade, but the crap aerial built into the rear glass. Unless you are in the city poor areas with strong signals they are complete rubbish. So upgrade your radio by all means, but you will have the same problem unless you fit a proper aerial.

Don't have the in built Sat Nov, but you aren't the first to complain about that on this site.
