1997 C280 A/C Trouble
 

Compressor was noisy on the drive home (pok---pok---pok). Next day EC light was on. No cold. Checked codes. 07 L0. Ran some R134a into system. 07 now 2.9 but EC light still on.
Here are the rest of the readings:

01 86°F
02 83°F
03 91°F
05 123
06 190
07 2°9
08 89°F
09 50°F
10 435
20 00
21 000
22 000
23 000
24 11.9
40 02
41 03
42 02
43 6-C
50 89°F
51 72°F
52 50°F
54 OFF

The temps look accurate (except maybe those 50°F-- not sure what theyare) the outside temp was low 80's. I don't know all the codes so any help in diagnosing would be appreciated. Charge leaked out overnight. I'm guessing compressor but how do I verify and is there anything else I can check?

Thanks in advance.
