can anyone tell me if they have had problems with the intermitant wipe not
working on their merc. I previously had a 220 and it cost me £120 for new
indicator/ wiper control arm, and the same fault has 0ccured on this 320.
also can any let me know how the air con works on the 320. the button is
marked E/C, but on reading the manual this says that E/C stands for economy
control. should i have this button on or off?

As far as wiper. test it by spraying water onto the windshield by the rear
view mirror. Make sure the wiper setting is set to intermittent.
If something is wrong with A/C the EC light will come on and you cannot turn
it off... meaning something is broken.... a sensor... last 3 times it
happened to our W210... it turn out to be the evaporator temperature sensor.
Don't just change the part... there is a diagnostic procedure to find out
which one is bad.
AFAIK, the E/C turns off the compressor (when lit), nothing to do with
how the flaps route the air streams.
Have a peek inside the engine bay, have a look at the lowest
pulley on the right hand (viewed from front of car). (for M104 engine)
This will spin if the compressor is active.
