different car, but on my 300SD I just charged the system up this morning. You can bypass the pressure switch and the compressor should come on....

But I had the same probelm this morning as you...the compressor wouldn't engage and realized that I didn't have the climate control inside the car turned on(simple thing, but easily overlooked...i.e. just jumping the switch is no good if the A/C isn't switched on).

But check your fusebox for the compressor as well and the connector to the compressor.
