As I mentioned before, when the AC system is overcharged with Freon, it can lead to the compressor working harder to regulate the refrigerant flow and maintain proper pressure levels. This extra workload on the compressor can cause it to draw more power from the engine. As a result, you will face more fuel consumption.Static pressure is only partial indication and yes 50 psi=3.4 bars is low pressure. My cars would not start AC at all till I had 5 bars static. Anyway, here is the best DIY help for AC I know. If your climatronic can't read the sensors, you need to use scanner for it. Read the notes at the bottom. Other than that, you are in mercy of mechanic.Turn On Your Car And The AC. Start the key and turn over the motor. Turn your fans to the greatest air setting. Turn on your AC.
