My 300SDL shows relatively high temperatures at the vents.
Temps are not going any lower than 10 -12C (50 -54F).
I have had the system apart, cleaned, new compressor, new condenser, new evap. and filled with R12. But maybe some air found its way in.
I already topped off one can R12 but still some bubbles at the glass and the pressures already high with not much improvement.
Can there be air in the system?

What would be decent temperatures at the vent on the stock system for the SDL?

Location: I am in Oman, Middle East with high ambient temperatures (recently 110/120F). Here is no one around who could vacuum, recover the R12 and refill. But I have another 4 cans with me, I also have gauges and a vacuum pump.
