[MBZ] **wiring harness on the W140 Diesel **

[Peter Frederick]

PIddling about at low speed carbons things up pretty badly on a 601, 
and a full throttle run will blow out all the loose stuff, pretty 
spectacular if it's been a while.  Most of it is probably loose soot in 
the exhaust.

My personal "tonic" these days is some contaminated fuel I add a quart 
or so of per tank -- one of my colleague's wife filled her car up with 
diesel fuel a couple years ago, so he was stuck with the ten gallons or 
so of gasoline with diesel in it.  Not enough to prevent the car from 
running (poorly!), and it burns in the lawn mowers, but not well 
(carbon fouls the plugs, smokes).  A bit in a full tank of fuel and the 
300D just purrs!
