so most of us with the 1.8t will be plagued by mysterious boost leak or boost surging. the biggest culprit is the charge pipe to the s hose with the c clip connection. over time the o-ring will fall apart and let boost leak by. this causes boost fluctions and leaks. a cheap fix to this is to buy 3 t-bolt clamps, silicone hose and a joiner.
what you need:
2.25in. x 3in. alum. or stainless joiner $10
2.25in. x 3in. silicone coupler $8
3 t-bolt clamps $10
Dremel with cutoff disks
now you need to remove the charge pipe, s-pipe, and pancake pipe. start by removing the silicone hose from the charge pipe and DV.
remove the clamps and set aside.
now remove the smaller silicone hose from the charge pipe.
now unbutton the heatshield wrap.
move it to the side and loosen the hose clamp from the charge pipe.
remove the wrap and slide the hose clamp down and out of the way.
next using the 10mm socket unbolt the 2 10mm bolts holding the charge pipe clamps.
there are 2 more down the backside of the charge pipe that need to be removed as well.
charge pipe should be free.
now to start on the bottom side.
you will need to jack up the vehicle and remove the passenger side wheel.
reach up and loosen the clamp on the top of the pancake pipe.
now find the 10mm nut holding the pancake pipe to the frame.
now find the 2 hose clamps holding the pancake pipe to the intercooler.
loosen them and you should be able to pull out the pancake pipe.
you should be able to see the s hose.
now go back up top to the charge pipe. remove it from the silicone hose to the turbo.
pull out the charge pipe and s hose.
here you can see the charge pipe to s hose connection.
use the flathead to pry of the clip.
