Exhaust Smoke
Lately I noticed that my W211 CDI has been giving out more black smoke than usual. Should I be concerned by this? I always thought that the high pressure injection should reduce the amount of smoke. If this is normal, more fun for me to spray a thick cloud of smoke onto others when I pass them on the highway.

240D smoke
If you are not currently using RedLine diesel fuel catalyst, then start - begin by pouring one entire bottle into your tank when you fill up, then add the specified amounts at every fill up. We have two 300 turbo diesels (one with 200+K and the other with 260K miles) both have had Redline since almost new and neither smoke even on heavy accelleration. You can find Redline at Pep Boys and most auto parts stores.

Are there any problems using Redline in my W211? I assume it would be fine in older diesel engines because of the low sulfur diesel fuel now being used. I don't want to screw up the common rail injection system or anything else in between.

I solved the smoke problem by accident actually. All I did was do an engine oil flush (using an additive which cleans out the sludge from the engine - done during oil change) AND by replacing the MAF (Mass Airflow Meter) on my '02 C270 CDI. Since then no black smoke at all !!
Here's a link to the stuff i used for the engine flush. There are other brands out in the market that do the same thing though.

having used protec for a number of years, i have found it to be the best on the market, eats other products alive. wait until you have used the fuel system cleaner or the aqua deisel this stuff is incredable my wifes old merc has a new leaf of life considering its done 130000 miles, the guys at mercedes are amazed at how good the performance is after 1 treatment, even in my car its performs like no tomorrow. having seen the before and after i will continue to use the stuff, 2 thumbs up to Protec autocare 
even if you are reluctant to use it at least have the decency to give it a bash, this product does what it says on the tin and with regards to environmental issues it BEST on TEST. they even have techinical back up as the guys in scotland are realy switched on with advice, heres their link

MAF location.
Kind of hard to explain. If I were there, I could point it out to you with no problem.
Look for an electrical plug connector somewhere between
your air cleaner and the inlet to your turbo.
This plug is connected to a spacer like part that fits into the air stream.
There is a fine electrical element within that calculates air-flow and feeds that information to your
computer which then determines what amount of fuel to supply, among many other things.
This part does not require regular servicing, and should be good for thousands of miles.
One thing that has been proven by the TDI boys:
STAY AWAY FROM K&N AIR FILTERS. Why?
Because the slightest film of fine missy oil on the element of your MAF will cause it to fail.
This has been proven time and time again by the TDI crowd.

Excellent site. It has a lot of detail repair instructions for all years of TDi engines.

Car had maybe 5-6k miles when I posted this. Now it has 15k miles and occasionally makes a lot of smoke when the engine isn't warmed up. No smoke though when I push the car to its limits once the engine heats up. I assume diesel cars run very cool when they idle.

The exhaust gas is very cool even in the summer. No smoke at all. I have 7,200 miles on the clock. Love this car. It is a great pity they do not make the straight 6 anymore. This car will be remembered as the last of the great MB diesels. Power. Clean enough technology without going overboard with half a dozen filters to please the Californian tree loving zealots. Cheap to maintain and less to worry about all the check engine lights just because there is a tiny bit of soot or NxO escaping down the exhausts.
