In Canada, the 190D 2.2, 190E 2.3 and 190D 2.5 did not come with headlamp washers, and was not available as an option.
The 190E 2.3-16V had them as standard equipment. The 16V came pretty much loaded on this side of the pond, as it was a VERY expensive car in it's day.
The 190E 2.6 offered the headlamp washers as an option.
The standard equipment lists for the various cars changed over the years, with the list shrinking in later years.
