[MBZ] 83 300SD update and ACC system

[kevin kraly]

We had the SD out today, I'm so happy with this great car!  The button next 
to DEF is definitely the way to go, and the system works very well!  The fan 
changes speed as it should, and it doesn't have to be HOT HOT HOT in there 
all the time!

I noticed an exhaust leak near the front of the car, and when it's idling 
with the blower on, there are exhaust fumes coming into the car.  It's not 
noticeable when driving down the road though.  I guess the air is pushing 
the  fumes toward the rear of the car and out of the ventilation system 
intake.  Another thing I've noticed is that the car idles better when cold 
than it does once it's warmed up.  There's one cylinder that has  some very 
minor but noticeable injector knocking/clunking going on, probably the 
source of the slightly shaky idle.  Once it's off idle, it disappears as 
does the shaking.  Once the weather gets a bit drier/warmer, I'll be able to 
start doing some fine tuning and, of course, a valve adjustment.
