Sounds very similar to my 2.2, never thought it was a problem.

Thanks chaps. There's clearly something amiss though, because of the occasional power drops that accompany the noise. Regardless though, it's in the garage now so I'll hopefully find out more later. Darren

Ok, I'm an idiot. Or oversensitive, or possibly both. Despite plugging it in, giving it a good look over and test drive, they couldn't find anything wrong. The noise, apparently, is just the actuator for the turbo vanes working and whilst they didn't actually say 'they all do that, sir,' it was definitely implied Embarassed

On the plus side, kudos to Challenger 4x4 for not charging me anything for this little escapade.

In the drive home, it behaved impeccably Rolling Eyes Darren

Only just seen this thread, and would have been reluctant to comment anyway given your username and normal knowledge levels

but.. as a couple of others said, sounds just like my 2.2 that has done it from new (much more noticeable with the window down) and as you say you can almost do it on purpose by throttle/gear changes. It has also been mentioned a few times, generally by new owners.

That must have completely passed me by, unfortunately. The only other related stuff I'd come across was in connection with the EGR valve, but that was replaced on mine last year.

Hey ho, you live and learn. Darren

At least it's extra reassurance for the rest of us. So far no one has said mine made that noise just before <something> happened Thumbs Up

So, despite all that I said above, this issue has still been niggling me. The occasional power hiccup and the odd noises convinced me that there was still something wrong. As a bit of a gamble therefore, I've replaced the turbo actuator and lo and behold, normal service has been resumed. Took it for a long test drive this morning to get it good and hot, and couldn't replicate the symptoms at all.

I can only assume that the actuator was sticking at one end of its' travel and then snapping back, hence the sound like a valve closing. I'll try and strip down the old one to see if there's anything obvious.

I was concerned that it might be a fault with the turbo itself but with the actuator removed, the linkage was completely free to move with no sign of anything sticking. Anyway, fingers crossed... Darren

Interesting narrative, sounds like you ‘knew’ in your gut something wasn’t quite right and it’s likely turning out to be true!

Yeah, kind of.

I've now stripped apart the old unit but disappointingly, there's no smoking gun. The inside is as clean as a whistle and when I applied 12v to the motor, it ran smoothly in both directions, albeit noisily one way. I'll just have to see how it goes.

Do you still have the strange sound or the replacement actuator sort it? WARNING.

Some time ago my actuator stuck on full boost (the well known chafed harness fault) and the induction noise was extremely spectacular!
