MB Ur-questions

["Jouko Haapanen" <joukoh@vtoy.fi>]

While I wait for my 1988 Urquattro (MB) factory repair manuals, there are
some questions I meed to ask.

1. The (vacuum) hose on top of the wastegate is not attached to anything. 
Is this the way it is supposed to be on an MB?  There is just approx. 10cm
of hose dangling free on one end.  The fiche refers to N 900 996 01,
shorten piece to 620mm.  Such an exact measurement, and mine is only 100mm?

2. What is the test procedure for the full-throttle enrichment switch?  Did
I miss it on the fiche, or is 443 906 277 D the right part?  The fiche says
F-85-D-900 001>>, but only refers to WR and GV engines.  Did I miss this
one on the fiche?

Thanking in advance (again),
