1.9 JTDm loud air noise!

Hi, any advice much appreciated! I have noticed very recently that the fuel consumption of my GT JTDm (2006) has not been as good as usual. On a long motorway run today, I noticed that whenever I tried to accelerate, I got this sound of rushing air and the acceleration was nowhere near as good as usual. Ive recently had a 60k service and also had the cambelt changed - is it possible that an air inlet hose may have been disturbed doing this work and has now come adrift, or is it something more sinister? It's difficult to pinpoint exactly where the sound is coming from, but possibly the rear of the engine @ drivers footwell area may be where it seems loudest.

Come adrift or may even have a split.

Check the large hose between the turbo and intercooler. It may well have split, also check the hose from intercooler to inlet manifold.

Thanks for the replies. Turned out to be the inlet pipe from the turbo, that runs under the gearbox. A known design fault, apparently, so I now have a modified pipe fitted, courtesy of Alfa Workshop.

Sounds like a boost leak...
