All seems to be running ok at the moment, at least It did on the 600 mile drive down to western France. (He runs into the garden and grabs the first tree)

I have been getting the odd chirrup from the car now and then when accelerating. Not something I can replicate, and it only does it occasionally. Probably half a dozen times since I have had it.....

Sounds almost like an old fashioned turbo waste gate noise ish......

Anyone else with a 4:4 get an odd noise like this?

Also I seem to have a slight flat spot in the power delivery as the secondary turbo comes in, so accelerated like a stabbed rat up to 2250rpm slight hesitation then goes again. I have heard of a similar problem on earlier cars but can't find the threads. I think a software update solved it but can't remember!  There is nothing that can't be fixed with a hammer😜😜

with our 3.6 TDV8 we had a warped exhaust manifold that caused a chirping on power. Not sure if thats the issue with the 4.4 but the symptoms sound similar.
NOt an easy fix, so I hope your cause is something else

Cheers, I Hope not but would have thought it would happen more regularly if that were the case.! There is nothing that can't be fixed with a hammer😜😜

Do you think it comes from the passenger footwell because SHMBO has mentioned something similar recently. 2016 (L405) Autobiography in Black with Ivory - for ULEZ
2014 (L405) VSE in Black with Ivory
2011 (L322) VSE in Black with Ivory
2005 (3.2 V6) Porsche Cayenne in Black with Savanna
1999 (P38) VSE in Burgundy (?) with Sand

Have you had the codes read? Just incase that helps?

Not driven ours much but on the odd 2 hour motorway run, I've noticed that from time to time on cruise control at 70mph, now and again there is the briefest sensation of the car surging forward then immediately holding itself back. Unsure if this is the 8 speed auto box self adjusting 'in flight' dependant on the road gradients; whether it's normal on the 4.4TDV8; or whether it sounds unusual (the SC didn't do it)?

Havent had them read yet Craig. It will have to wait until we get home, should really get me an Iid tool  There is nothing that can't be fixed with a hammer😜😜

Mine does this too occasionally. It is usually when I'm slowing for roundabouts or junctions, at about 10-20 mph. Also noticed acceleration can be flat sometimes too. Due for a service soon, so I'll mention it then, unless anyone thinks it warrants more urgent attention. Btw it's just clocked up 90k, so hopefully the turbo's not on it's last legs!

My 4.5 TDV8 is also started to make this noise. Sometimes it's very quiet, other times it's quite loud. Just been round to my local Indy and took one one the mechanics out for test run and he also heard it. They have never come across this before.

It normally happens when accelerating gently away and appears to occur at a gear change. The noise seems to coming from the front right of the car. My first thought is that it sounds similar to a turbo waste gate noise, as per previous comments.

My car is now booked into the Indy next Friday for investigations

Perce, just wondering if you got a resolution

Post up the results, mine seems to be still only doing it occasionally, not really noticed it too much since getting back from France! There is nothing that can't be fixed with a hammer😜😜

I´ve the chirrup only at 1100 rpm in road, this seems a vibration of metal. The car stayed one week at LRS, unfortunately they not discover the origin.

My car is still making this noise and on a more regular basis now. I've tried searching the internet again to see if I can identify the root cause and found this link. The noise this car makes is exactly the noise my car makes.

Anyone has this on their car?

My 3L TD6 L322 makes a more canary like high pitched chirp when you come of the gas (you can hear it if the drivers window is down). I assumed it was a normal turbo waste-gate noise. Is this not correct?

mine is still doing it occasionally, as you said originally it seems to be on light throttle when changing gear still. Hasn't gotten any worse though. There is nothing that can't be fixed with a hammer😜😜

I hear mine do it when I'm backing it into my workshop, when I have to press the throttle to get up a little slope and then come off it quick. Doesn't seem to do it going forwards, but then I don't suppose you come off the throttle as quick....

Who knows....
