Mine does that. I put it down to the turbo spinning up with partial throttle. I'd describe my noise like a Dolphin "Whoooooosh.....eee...eee...eeee.....eeee" almost like turbo chatter, but very very faint. I've done 30000 miles in 10 months since I got the car and it hasn't got worse or broken. I notice the same noise from the 1.9 Astras and Insignias etc that use the same engine.

As mentioned, lob some injector cleaner in.

the noise you describe is simply the turbo spooling up, it will change sound as the engine catches up with your throttle input.

if the car is pulling hard i dont think you have a problem#

and if the feul consumption is lower that 40MPG its because you driving it to hard listening to the engine makeing whooshing sounds !

Mine does that as well but higher up rev range it started at 2750 now does it at 3000 no noise though, mind you always have radio on so i may not hear it .Not bothering me as the car is going great at the min lol.Thought it may be the vacuum valve on the turbo sticking slightly its on the right of the EGR as you look under bonnet .If you get someone to start it the lever should move .If it was a big problem you would have no boost at all .I spoke to Gus about mine he is a expert on these cars and its not a problem he has encountered before .Dude its an Alfa great cars but some would say odd things go on lol. I would turn radio up and drive car it may sort its self out dont think its anything Major .You know anyone with same car if so try blag drive or ride in it so you can compaire performance you will then know if yours is ok .Mines been remaped and decate pipe fitted it pulls like a train always feels eager is yours like that if so not much wrong with it .I would use the millers it will keep the inside you engine soot free and you get better performance and MPG

I like the spool up noise, driving through town getting it to go "Whooooooosh", then "eee eee eee eee" as I lift off. Only does it on partial throttle between about 1700 and 2000rpm.

So the noise seems to be normal, lob in a few doses of injector cleaner and see how you get on

My JTD also makes that kind of noise when driving around town. If it goes well and doesn't use any oil or excessive fuel then all is well

had the hesitation on mine at around 2-2.5k rpm not massive but noticeable and makes it uncomfortable to drive in town. Turned out to be the gasket between the egr valve and the inlet manifold, egr had been of several times and they just used the old gasket. Updated gasket available from Alfa Workshop Part No: 55225287

Hi maverick. To be honest I don't see how it could be the gasket since mine looked pretty intact. It wasn't deformed or dirty and I tightened it pretty well so there shouldnt be any air leaks.

on mine it was the original gasket but once removed it was obvious where it had been leaking and once replaced it was smooth through the rev range.
