Problem (2002 CLK320...same system as E320): A/C will not start 1st time and is stuck on EC. If I restart the car, it turns on. At first I thought it was a leak, but after I put my gauges on it...not so!

My A/C gauges @ 1500rpm show Low: 35psi High 235psi
So its charged.

Could it be a sensor?
Here is the readout from the A/C control panel:

1. 70
2. 88
3. 45
4. 43
5. 40
6. 181
7. 16
8. 94
9. 25
10. 5.1
20. 4.0
21. 6
22. 0
23. 0
24. 14.1
40. 8
41. 5
42. 200
43. 134

Any ideas?
