My W211 E220 AC started blowing warm air. The pressure got so low that the on board computer disabled the compressor. The red AC light flashed and then went out. (UPDATE 22/8/16: Still Cold!)
I wanted to fix the leak and recharge with r134a but the compressor needs to be running when you inject these two.
This is how I approached the task.

You can skip the code reset on a w204. 🙂
Why arent all YoTuber videos this good. Its the same problem on my sons CLS and now all I need to do is clear the fault code. I have an OBD2 tool but not mercedes specific so hopefully that works or its a wallet tickler for a new one.. Many thanks. (You dont do a video how to identify which park sensor is goosed on a CLS do you 😛 )
Name of the multi-system that he used: ICarsoft multi-system scanner i980 for mercedes-benz.
Can you tell me the model of your diagnostic tool or what I must search for? I have also w212 face-lift
Please my Mercedes w211 e200 A/C does not chill when in a traffic or driving at a slow speed. What could be the problem?
I had to swap out expansion valve did everything besides clear the code, so tomorrow I will be getting a acon reading to allow the compressor to come on and stop the blinking light. By far the best video I have come across. Thanks.
Fantastic! – I have the exact same problem in my 2008 e-class –> now i know what to do 🙂
Seen several vids (23ish) on this subject and this is by far the best, most comprehensive and thorough vid I have seen. Thanks for such a good job.
Are you sure it wont spoil the compressor cause some guy wrote a bad comment on amazon about his compressor got blocked cost him 2000$ but he bought some other brand also in my country mastercool 53909 or 53910 is available ?
