Engine: D5: V70 very inter power loss cured !!

Firstly sorry you have changed the intercooler un-necessarily , but the word swoosh did relate to that , and it should be obvious it is blowing when it is removed for examination .
"Squeal" is a different kettle of fish and may well be the turbocharger .
When it is cold remove the rubber air inlet pipe to the turbocharger from the air filter and try and spin the impeller with your fiingers . it should spin freely and continue to spin for a short while . also there should be no end play, ie in and out axial play but some side play is permissable but if it's flopping around then probably broken you cant diagnose these things remotly so it would be a good idea to get a dealer to spend 30 mins comfirming the problem , if it IS the turbo then you need to find out why it failed , number one cause is poor oil supply to its bearing , either the wrong oil or a restricted supply ... Turbochargers dont usualy fail for no reason and dont usualy "wear" out ..

Good Luck

Thanks again for your quick reply, i will examine tomorrow night i always am a one for checking oil level weekly and always service myself with original filter and 10 40 semi sim oil but you recommend another oil? was it 0w 30 ? can the oil feed pipe get clogged up,thus oil stavation? but i have no oil leaks or low levels or any from the exhaust? ?

you will get better fuel economy with the 0w.30 A5 B5 spec oil ...

I have seen a D5 go for "only" 36000 miles from new without an oil change and it was covered with about 8 mm of thick grease like substance all over the inside of the engine , it failed due to the oil being unable to get through the sump strainer .. the turbo was the first thing to fail ..

Thanks for that i will change to that oil in future,but do change every about 8k miles i have just came in from my garage looking at removing the turbo off the engine,i take it you have removed many off before, i have got the car on ramps removed the engine bottom cover removed the in and out rubbers pipes removed the top cross member engine mount bar for better access and the only thing that looks tricky is getting a tool to undo the 2 torx bolts on the underside of the turbo oil feed? and the top oil feed also do you just remove it from the top of the turbo,but does this cause it to be awkward to take the turbo upwards out of the bonnet area? as it looks to me as if there's hardly room to take it out upwards? and also the exhaust bolts look seized? Any advice on all of the above please

i have replaced the inlet turbo rubber hose at £62 incase of load collapse,
i have replaced the turbo governer at £133 and intercooler at £221,and the noise is getting worse,think it must be the turbo?? possible faulty waste gate or dump valve or just knacked turbo??
but is ok when not towing only a lower air turbo spinning noise can be heard(not when i change gear-it is constant)
ps when i removed my old intercooler found the date on top of it which was dated nov 06,so it must have already been replaced as my xc90 is a 54 plate sept 2004,i bought the car a month before it was 3 years old at 118k miles and now its on 133k miles as i only use it for private family use,so a bit gutted that i did not need to replace it,to be honest wish now i had taken it to a volvo independent as i have spent a lot on it for parts and my own time in the garage and yet to no avail , anyway any advice on my turbo please and what to check for and how easy is it to remove the thing from behind the bulkhead and do i by new a second hand or is it a simple repair?? any input would be kindly appreciated-regards

99% it's the turbo. The question is why it failed twice?
I had to replace turbo in my car because it was giving an over-boost. The vanes in the turbo were stuck.
You can check the turbo only from the inlet side. Take off the inlet hose and look for scratches on the casing around the rotor. Grab the shaft and try moving it around. If there is a lot of play then your turbo is gone.
Compare it with my turbo: http://volvoforums.org.uk/showthread.php?t=97831
That's the used unit which I fitted to my car and it's ok.

Just something to consider. I had a screeching sound coming from my turbo a few months back. Didn't happen untill the turbo spun up and when under load it was ok. When I lifted off the accelerator and let the revs drop the screeching would begin and it sounded awful.

Took the car into my local inde and had them have a look at it. My turbo had come lose! They checked it and retightened it and everything was hunky dory once more, no more screech.

volvo xc90 se d5 54 reg 133k miles (6 speed manual)

Hi just to say after having "urgent engine service required" message's having replaced my intercooler,turbo governor,top turbo pipe,and still no joy after £420 just for bits, and replacing myself, so no labour charge,still had noises and faults, which i only had when towing my caravan underload, and drove fine when not towing, when towing up hill it was getting worse firstly wooshing noises then a few months later with squealing, and a kind of grinding noise, and worryingly a few times the engine nearly cutting out at 60mph, which i put down to exhaust being blocked?It kind of got me thinking after that it must be the turbo,anyway it was to big of a job for me to removed the turbo myself as on the xc90,as you have to drop the engine a little to get the turbo out from behind the bulkhead due to lack of room, and i priced up the new turbo, and the best price i could get was £770 inc vat from volvo and aftermarket one were even a little more expensive,anyway took it to a volvo independent specialist,which i have used before,and i told him to tow with it otherwise you would not know really,after 2 days he phoned me back after checking all hoses with infra red dye for leaks and pressure testing mounts pipes etc, and putting a camera down exhaust to check for cat blockage's etc,then towing a car on a trailer he confirmed to me it was the turbo afterall,anyway he put a genuine volvo turbo complete on after ordering from sweden, and i picked up a week last wednesday,he said it is a very awkward job as he always likes to completely remove the oil feed pipes and check for blockages and replace all gaskets etc aswell, and he told me to run it in for a a few hundred miles, which i did then this week towed our caravan down somerset and back last night,and glad to say now my xc90 is as good as new again,due to it being chipped it flies even up hills on m5 by bristol 60mph with caravan in 5th or 6th (manual box) is no problem,and i laughed as i see all land rover based 4x4's struggling up hills and the xc90 d5 leaves them standing,and i had to laughed again as on the m42 a AA pickup had a large caravan on the back with a discovery on the flat bed lol! I say this as i had a range rover with the bmw 2.5d 6 pot engine a few years ago and can say it was the worse car i have ever owned for reliablity and was hopeless towing with any descent speed (manual aswell) so i know my xc90 has just cost me £1150 inc vat to sort out but i have had it for 3 years now and with 133k,so i will always trust volvo for my transport
(ps got him to do me a oil change for £60 extra 0w 30 fully syn oil and filter and is at least 3-4 mpg better than the 10w 40 i use to use so will be sticking with 0w 30 in future-just glad now car is back to normal) thanks to the volvo specialist -top guy ! Knows his volvos as he's also a volvo nut !

I think you need to go and take some driving lessons on towing and carefully read the highway code
