I heard that the compressor is always on unless the climate control is turned off or the EC button is turned on. This applies (compressor on) even when you are heating the cabin.

Charles, what does PBU stand for? I use the N22 read out for information like that also.

I am guessing item number 7 is the pressure in bar, correct? I don't have the list off hand, it's in my visor in my car. Now, can we tell if there is a leak or not by monitoring the pressure? What seems to be the "normal" pressure range and what pressure should we be concerned with? Anyone know? Hopefully Steve B will come and help us out.

And Benzfan, I agree with John S. on trying to put the blame on one of the AC shops.... though I'm assuming that would be rather difficult, but it's definitly worth a try and some persistence (for the $2100!)!
