Guys,

I must thank each and everyone of you who have responded to my previous
posts about my new-to-me pride and joy - E-420 Sedan.

I have another query.
After I received the car back from being serviced, I noticed the
actuation levers (turn signal AND cruise-control actuation) mounted on
the steering column were LOOSE.  That is, these two stalks are mounted
to an assembly that fits around the steering column.
When I stroked for making either a LEFT or RIGHT turn signal, the whole
assembly shifted down or up and I had to push further to get engagement.
 A few days later, the whole assembly was TIGHT.  It was as if the
problem never existed.  The mechanic said he'd only worked on the
passenger side (changed the charcoal filters for the cabin air - they
were filthy by the way).
Well, today (about a week later), the looseness was back.  The weather
here was unusually hot today and the car interior was even hotter.  I'm
assuming the temperature must be affecting something.  I took the car to
the mechanic and he had never heard of any problem like what I was
describing.

Again, I'm appealing to the wisdom of a higher court (this
newsgroup/forum) for any background information anyone may have about
what I'm experiencing.

As usual, thanks in advance because I've always been informed by
everybody's responses.
