= higher EGT, but within the limit. My old Bosch guy said every Diesel
should have an EGT gauge. I looked into the price and having to get a
nub welded on the down pipe 40 yrs ago and the finances voted against
the EGT gauge.

My '83 300D (same drivetrain as yours), which also doesn't get
driven much, does the same thing. It sort of "hammers" and
shakes the engine at idle in any kind of weather.
I vaguely recall that carbon buildup isq supposed to be the
cause and the cure is to lug the engine up a long grade with the
engine temp topping out.
Not lug! Lugging is high load, low RPM. That is not good for any
engine. What you want to clean out the engine is high cylinder
temperatures. So high load, high rpm, full fuel. There are a
couple hills around here that are big enough and long enough and I
try to "treat" the engine every time I climb them. The turbos
need a bigger hill to do it well.
Just high RPM isn't enough, so running the engine against the
governor in a low gear isn't effective. It is the heat caused by
max power and high RPM that clears junk out.
