How much refrigerant should be added to a Mercedes-Benz E300 at one time?

Mercedes-Benz E300 refrigerant should be added about 6 liters at a time. Here is some related knowledge about the Mercedes-Benz E300: 1. Interior: The dark gray interior appears relatively youthful, paired with brown seats, giving a high-end feel. The focal point on the upper part of the center console is the large-sized GPS navigation screen, which is impressive and substantial enough, while the middle section houses the audio control buttons. 2. Exterior: The front face design is identical to the imported version, with the split-style high and low beam lights featuring sharp lines, creating an overall youthful and dynamic effect that completely washes away the "old Benz" image. The LED light group below the front of the car interprets the word "fashion" even more thoroughly.
I recently saw discussions about Mercedes-Benz E300 air conditioning issues on forums, where everyone emphasizes not to randomly add refrigerant. As for the exact amount, it really depends on checking the manual or directly consulting a 4S shop. Generally, older E300 models use R134a, while newer ones might use R1234yf, with system capacity fluctuating between 600 to 800 grams. Never estimate the amount yourself—overfilling can cause compressor pressure to skyrocket and damage it, doubling repair costs. I recommend checking if the air vents feel cool before each drive. If cooling is poor, first visit a professional shop for a leak test before precise refilling—it’s cost-effective and safe. Regular maintenance of the AC system can prevent sudden issues, avoiding the misery of driving without AC in hot weather. The labor cost is just around a hundred bucks, but it’s worth it.
