Just picked up a c270 cdi estate. With the recent hot weather the speed at which the car cools has surprised me. Seems to take a long while to come down in temperature. If I turn the auto-off and put fans to max and temperature to minimum (it's the heatmatic I think - auto but with dials not lcd display) the air coming out doesn't seem to be what I would call icy cold. It's my first merc so not sure if this would be right? How can I check this to see if it's working or shall I just go back to the garage for them to check.
