[W126 Coupe] The Continuing quest for finding Vacuum Leaks

[Dick Spellman]

Dan,

You can block the vacuum feed to the elevation circuit temporarily with a
piece of vinyl tape.  FWIW, the controlled leak on the dial is more than
offset by the vacuum resevoir in the fender when all vac circuits are
intact.  I'd replace the line and place the headlamp elevation back in
service.  Do you have the factory guide for setting up the lamps with
elevation?  Also, that service is tied to the rear suspension on your 560.
The dial is a manual over-ride of sorts.  Where I don't have the hydraulic
suspension, I set the headlamps up so I could elevate as needed on
particulary dark nights ie with wet pavement, poor street lighting, rain,
etc. and without then need for operating the high beams that would
interfere with opposing drivers.

Let the list know if you need the manual.

Dick
