re. Help - 200TQ big boost leak on trip

Sounds like you shold be looking for a leak at the ECU where the line goes
in - probably a cracked pressure damper - the clear plastic  thingy that
looks like a fuel filter without the innards.

We are on our way from massachusetts to michigan and having a problem with
the 200. Under boost, there is a surge of air into the cabin through the
vents. The engine bucks a little also. I turned off the climate control and
still the same so it seems like a big boost leak. I looked around the
pressure hoses and can't see anything obvious except a small amount of oil
on the rubber hose from the J hose to the intercooler. I don't want to mess
with it on the road and make it worse since I don't have many tools with me.
I thought that you could force the engine to boost by pinching off the lower
wastegate hose.  At least then I could hear where the leak is. If anyone has
any ideas or can help, I am headed down I90 almost to NY. I'm mobile on the
laptop so I will get any emails right away.  For now, we will try to stay
off the boost.
