Where is this smoke coming from??

[Koum]

I know this isn't a great deal of information but is anyone able to help diagnose? 

It happens obviously allot more when the car is warmed up and it seems to be coming from the left hand side of the engine bay around the turbo but not actually the turbo.. 

 

Something is clearly leaking but just hoping someone may be able to know something thats common issue that happens around this area?

Is it the oil pipe or breather on turbo.

The second pic looks sooty, so maybe you have an exhaust gasket blowing.

I hope you don't have a cracked manifold.

Well, from the video it would look like the front of the exhaust manifold is leaking, but it is hard to tell.

Does it look like it is swirling around the front?  That would suggest it is blowing forward and then the fan is pushing it back.

I was thinking manifold because of the sheer amount of smoke plus it smells so bad in the cabin exactly like the exhaust :s

Yes it swirls as you say, when it reaches the fan... guessing its the manifold i suppose i need to investigate further but know its not an easy task to remove said manifold.

Turbo seems to be acting fine though comes in as and when it should - would it effect its operation if this was to be bad?

 

It also has a layer of some kind of soot on the plastics? so again i suppose this suggests the manifold?

It is looking likely.

Not sure how feasible it is now, but in the old days we used to disconnect/stop the fan and move a bit of tissue paper around the manifold to see if air was escaping.

Will try and give this a go! will have to wait until the weekend for now just hope it lasts until then!

Can't seem to find a guide on removing the exhaust manifold. Does anyone have any link to a manual or anything of any help?

With how fine the soot is and where it is, I'd suggest checking the turbo breather pipe. I had a very similar issue on my 407 2.2hdi.

So this is where the leak was coming from was missing the bolt circled as shown.

Replaced this and the leak has gone, however I don't think that's going to fix everything and believe that its all backed up everywhere and the whole system needs clearing out.

Going to be doing intake and manifold clean and may even replace the DPF as its caused nothing but issues however no more check engines in the recent months so thought it had cleared itself out... obviously not...

Also check out this air filter !

Got to ask .... when was the last time the car was serviced or the filter changed at least - that's shocking

[Koum]

Well I've owned the car 2 years and haven't done the air filter until now but it really shouldn't ever get to a condition like this 

 

[is200 Newbie]

Depends on the environment the car is used in but I agree that it should not get into this state. Don't think it is linked to the soot as the car pulls the air from the front grill area unless there is a hole in the system and its pulling soot through ... what does it smell like ?
