Hi guys,
I logged my car the other day with a friend and the data we collected showed a weakend boost level. So i pressure tested my car. The only tiny hiss noise came from this hose(the left on). the hose seems not to be a part of the main pressure system.What does it do? I will replace the hose of course, but can that cause the little weakend boost pressure. The boost reaches 1.0 bar as it should but the logs show that its going down slightly.
Someone got that leak too?
Thx for hints and comments

 

Another pic u see the hose better.

 

That venturi check valve is quite notorious for failing. I'd replace that for sure. Part number is 996 110 652 70.

Number 9 in the picture.

 

Hi there,
Its actually the hise with number 6 which is hissing. Its connected to partnumber 9. Thats a pump...what ever it does....

 

Oh, u think that pump nr9 is shot? Ok...i replace that.

 

Any hints to get this thing out? Looks like removing the 3 clamps from the hoses leading to the pump and boom. Or any problems known? Some tricks necessary?
Thx in advance

 

Guys i need a quick hint.
Nr. 21 is damaged i need to replace it. But I dont know which way to mount it. Which way the air flows? up or down?
Thx for hints.

 

Ops...forgot the picture

 

Air flows into the plenum. In that pic, the air flows down.

 

Great thx alot.
