Hey guys, haven't been on the forums in a while.

Since its 187 degrees outside and 325% humidity, I'm trying to get my 240D's A/C running. The system is bone dry due to a leak that caused the previous owner to re-charge the system about every 3 months. I'm currently trying to charge the system myself and I cannot seem to do it. I jump the compressor and start filling on the low pressure side, but the pressure just keeps increasing, and I'm not seeing anything in the little sight glass on the drier. It's charging up to about 50-60 psi and the engine bogs down considerably when the compressor is engaged.

Is something wrong? Do I keep filling on the low pressure?

I read that you might need to charge up the high pressure side, but only if it has 0 pressure, which is does not. It has pressure on the high side.

I'm afraid to simply keep filling the low pressure because the pressure just keeps rising. It doesn't seem like the system is accepting the freon. (R-134a)

Any help or suggestions are greatly appreciated.
