Hi,
I've got a W210 320 Cdi and I did the A/C diagnostics test and it came up with the following error codes:

1) 231 ECT Sensor
2) 416 Coolant circulation pump

I managed to clear the first one. As for the 2nd one, problem is, it's very cold here and it's hard to tell if the A/C is working. The car is new to me and I have just had the refrigerant refilled. From the diagnostics I got a Refrigerant pressure reading of 8 bar or 113 psi (shouldn't it be 300 psi?).
Does this mean that I have a problem with the A/C (the pump???)

Also there seems to be some problem with general airflow to the cabin, the fan is blowing ok, just not into the cabin! Could these be related?

The actual diagnostics figures I got are:
....after start......after 5-6 mins
#1....19..................20
#2....10..................11
#3....21..................34
#4....20..................33
#5....16..................07
#6....24..................36
#7....05..................05
#8....17..................16
#10..1.2.................1.2
#11..2.4.................2.4
#12..4.1.................4.1
#20..0.0.................0.0
#21..07..................07
#22..00..................00
#23..00..................00
#24..13.3...............13.3
#40..74
#41..30
#42..08
#4..136

If you see anything suspect let me know!
Thanks.
