turbo adapter clip hose no tight....

[Master Sylvain]

have been checking for boost leak on my 2.0 tdi engine
i need to know if the turbo pipe adapter must be tight or have a little play i mean a bit loose
need some advice check the video ..

Looked at this and it doesnt look good - the outlet of the turbo should be secured as it is in fact a pressure line - if its loose then you will lose boost and that will result in a performance drop. See if you can have a look at another model and do the same ?

The hose should b properly secured to the flange, that flange also looks kinda loose aswell - maybe some thread lock on the threads to secure if there it does screw in...

Thanks for reply
are this causing the car to smoke ?
I went to audi for the part they charge £160 for that turbo hose pipe + the adapter to turbo.
where could I found this part for cheaper but good quality ?

I agree, should be airtight

The smoking is due to the engine fuel being metered by the air being sucked into the turbo not in balance with what is being injected to the engine as boost is escaping resulting in the combustion being overfuelled... and lots of smoke. Get it sealed up and it should be okay

Today I change the whole turbo pressure hose
And I seal it up with this
I even change the MAF too
I pute this engine cleaner to clean the carbon build up
And I went for a 20 miles hard drive on the motorway
engine and turbo sound really better with some power improvement.
At driving car smoke fare less and no more iddle issue
on motoway no smoking at all but as soon I park in my drive and reversing there is some smoke come out .

there is my question what possibly can cause the smoke ?

Did the RTV Silicone hold up at the charge air hose? Did you put it on the turbo outlet side, or on the other side, where it connects to the hose going to the intercooler?
