[urq] Re: Upper Wastegate Hose on '83 Ur Quattro

[Brandon Rogers]

Based on my experience with the WX, one of the first things an owner should
do on these cars is just go ahead and replace _every_ vacuum hose - it will
be somewhat of a PITA, but I believe it will save lots of time and running
issues over the long run.

Thanks for the replies from all.  From what I gather, the upper wastegate
does not really connect to anything.  I was seaching for something since
someone had put a hose on the port, which did not go anywhere.

I replaced the lower wastegate hose and tightened some clamps.  That fixed
the problem.  Funny - the hose was not torn, although it did not look too
good.  When applying pressure to the hose and holding the other end closed,
if it was leaking, it was a very small leak - more like it was weeping
pressure slightly through the walls in various places, like it had gotton
porous over time.   I guess it was enough to cause the overboost problem.
Probably a combination of the adjacent hose not being clamped very tightly
after I did some recent maintenance, and the lower wastegate hose getting
kind of raggy.

I was holding off fixing all the worn hoses, etc. because I am going to put
an MC in it, but that won't be for some time, so might as well enjoy driving
it.  So need to charge the AC next.

  Where does it go?  There is a hose attached to mine, but it doesn't go
anywhere and I see nothing in the vicinity to connect it to.

  Hard starting and overboost at about 1.9 bar prompts me to  investigate.
I probably need to replace the lower wastegate hose, but the upper is not
connected to anything right now and maybe that is the main culprit.
