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

[Ben Swann]

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.
