Notwithstanding that there is a high likelihood that it's the compressor... OP, have you put a set of gauges on and *confirmed* that you have a proper fill?

Yes, I checked several times and it was loaded properly (440g). It's just weird to me: When I just charge the air conditioner while the connections on the air conditioning pipe are still connected and turn on the air conditioner, the compressor immediately starts working and the fan starts. So it is about the fact that while the air conditioning is being charged and the air conditioning charging machine is displayed on the screen that the charging is over, the air conditioning starts working without giving gas (over 2000rpm) and the next shutdown of the vehicle continues the same

I have seen often that older cars need more than the spec of grams of R134a. Do you recall the high/low psi when it was working?

That said, symptoms are off failed variable compressor

When the compressor is running low and high pressure are as they should be on the correct compressor, this is what the mechanic told me. And he told me he suspected the valve

Does anyone know where the FM singal amplifier is located or what could be the problem? I have radio interference, it works a little well and sometimes there is a lot of noise

Backup camera? Also how's that connected to "problem with AC"

Not to open a new topic all the time, I wrote here. Do you think the e53 has preparation for the rear camera?what could be the cause of the noise on the radio?

You should start a new topic for any different problem. Illogical combining causes problems to solve any additional issue.

The FM uses wires in back and back left window for antenna. I don't think that's the connector for it I think that wire goes though a side connector but that's a guess.

AND close off this A/C thread with the fix.
