Right car I've bought whines through all gears , travelled 500 miles since having it and apart from cringing from embarrassment the car as performed fine.
Actually noticed around 30mph in third gear its shudders slightly and also noticed similar at 50mph average speed cameras in fifth.

Checked air intake and found orange turbo sleeve had split , paid £18 at Peugeot parts as was desperate and thought I had fixed it (placebo)
Guess what its still there.

Unplugged air pipe altogether and the whine is still there I'm guessing obviously turbo sounds like a police siren.
Harder you press the gas the louder it goes until your crushing in fifth you don't hear it ...

Checked turbo spindle no obvious deformity,
Noticed oil in damaged sleeve and check after putting new sleeve on today and doing over 100miles fresh oil...


Please help!!!!

Had the exact same problem, check the edges of the impeller blades - if they look scored then the impeller is being drawn against the turbo body.

As storeman says, the pick up pipe filter could be blocked, it's an infamous issue on these engines, read here for more info, also see here

That's the same noise as the one we had, it's the turbo on it's way out. It looks bone dry too.

It's not just a case of sticking a brand new turbo in either, you need to replace the oil feed pipe, and give the engine a good flush with oil changes. There's info about it in the links in my previous post.

The turbo is easy to get out on these, as it's right in front of you.

The cartridge would be ok, providing you follow the rest of the guidance on cleaning out the entire oil gubbins (sump, lift pipe etc). Even then, there's no guarantee that any attempts to fix the issue will be 100%.

Some recommend getting everything brand new, OEM quality rather than aftermarket. Including a new sump.

Have a read of the guidance info and see what you think.

Read the links thank you ,

Got a confession too the car I have is not a 407 but a xsara picasso the forums aren't as busy as it is here and all the searches I've searched this forum trumps the others .
So sorry.


Spoke to a garage in Bradford who have said this
Labour: £140 Remove and install turbo. Clean oil feed pipe, oil strainer in the sump.
Parts: £240 Reconditioned turbo charger and gaskets
Total: £380

Does this sound roughly right?
Is there a specific turbo I need?

No need to confess..... Peugeot, Citroen, they're the same underneath!

Personally, I'd ask for a new feed pipe. The sump will be ok with a good clean, if possible a new strainer would be better. And new filters and good quality oil is a must.

You may want to clean out the EGR, intercooler pipes and check the intake too, they're fairy easy DIY jobs.

A reconned turbo would be fine, but make sure you get some sort of warranty for it. It might be difficult due to the nature of the fault.

The cost looks fairly reasonable though, can't fault that.

That's what'll need doing. The issue is not with the turbo, but with the level of preventative maintenance from day 1.

The video shows how to clean the system, but it isn't a guaranteed fix. Sometimes the carbon build up can be severe enough to mangle a new turbo within a very short period of time. Which is why new parts are recommended.

The 307 we had at work which had the same issue had contamination at the top end too, so it was more or less goosed.

I've got the car booked in for Monday managed to get a reconditioned turbo for £180 with warranty from a specialist,

Is it worth paying for a new strainer , banjo bolts,
I've read a few posts on here about removing the filters from these , and buying an OEM oil filter and not trying to buy the cheapest oil filter.
Oil invest in premium 5w-30 is that right and recommendations I don't trust garage oil and have read I need low ash content decent oil.

Any other things to add guys,

How do I check my injectors are okay , as I've read they can come loose any specialist tools do I need to tighten as also 'read' again these are very delicate



Sorry for all the questions

And again thanks everyone

It's advised that OEM parts are to be used, even if that means paying more.

You can check the injectors by doing a leak-off test (I think there's a DIY guide somewhere on the forum). You can also remove the injectors and inspect them visually. That way, you can also check the copper seal washers and replace as necessary.

Lexia3 and Diagbox can show you the injection rate, other systems such as Delphi can show this info too
