C230 Kompressor Sport

I need to know where you install freon in a 2004 Mercedes Benz C230 Kompressor Sport

If you are not mechanically inclined, and frankly, if you do not know where you lines A and C / are, you're not. Leave this task to a professional mechanic, if it just needs freon it will not be long or too expensive. This is not the same as adding windshield washer fluid or a pint of oil and, in some states it may be illegal for you to alter the system. I do not want to tell the good, but if you can afford a Mercedes, you can afford to have it properly maintained.

In the line of low pressure.
