Avensis 2.2 D-cat goes intrerrupted when accelerating

[Nicku]

Hi guys,

 Looks i get rid of one pronlem so i can get another one....😩😩😩. The turbo is wisseling little bit loudor tha usual (but not very noiceble), and when i go over 2000 rpm the enhime runs in hopes, sudden los of power until 2800 -3000 rpm when everything goes back in normal. I mention that only in second and third  gear. Overall no lose of power, no smoke no nothing. Avendis 2.2 D-cat 2006. On tester, the turbo pressure is ok injectors ok  i cleande the EGR (vasan't very dirty)...🤔🤔, I did not tested the vaccum pump and the vaccum hoses.

 

Any advice where i could start ?

I would check all of the pipes and joints of the turbo system, where the air goes from the intake, through the filter, into the compressor and the intercooler and back to the engine. It could be that a split or a loose joint is letting the pressure escape intermittently. Also possible is that the vane control valve is sticking or bad, or the vacuum control solenoid or vacuum lines to the vane control valve have problems.

I manage to find the problem... The intake hose ( the one that conects directly to the turbo) was loose.  I changed the loose metal clamp and everything is ok.

Thanks.
