It is a common problem... no preventive measure unless you just don't use
it that much. People who uses it all the time finds it died early.
Just get it repaired... a Colorado outfit does great job... go to
mbcoupes.com and look under part supplier.
The cruise control failure is pretty will understood and even easier
to fix - in most cases.
Take the mofo out, resolder every connection. EVERY connection. 99% of
the time that fixes it. The other 1% of the time you guy a good used one
from a scrapyard, (resolder it!) and install and go.
To answer the original question, well, uh, you could resolder it now
or wait till it breaks then resolder it.

And by mofo, he means the cruise control amplifier located under the
dash. Never tried the resoldering idea, but have replaced the amp in
my 300SD once and it's currently out again. Like much of the German
electronics, it's the weakest link. Currently, I'm dealing with a
whacko tach and that's because the tach amp has gone again.
