[W126 Coupe] Re:IDLE AIR VALVE VOLTAGE

[Steve Nervig]

I don't believe so, Malcolm. MB dip stick guide tubes have reached to  
within a couple of mm of the bottom of the sump since at least the  
early 80s to facilitate changing the oil by sucking out of the oil  
dipstick tube. That's how the Topsider and similar contraptions work.
