How Many Grams of Refrigerant Should Be Added to the BMW 5 Series Air Conditioning?
2 Answers
BMW 5 Series air conditioning refrigerant generally requires a refill amount of around 600-800g. Specific amounts are determined by the vehicle model: Each vehicle model has a prescribed refill amount, which is indicated in the car's manual. Alternatively, the refill amount can be controlled based on the pressure gauge reading. If a dedicated refill machine is used, it can be set automatically. Currently, refrigerants on the market are typically sold in bottles of 220g or 250g. Mid-range and lower-end models usually require 3-4 bottles, while high-end models require 4-6 bottles. Refrigerant Introduction: For the BMW 5 Series, refrigerant is typically added every 5 to 6 years. Refrigerant is a working fluid used in refrigeration and air conditioning systems to transfer heat energy and produce a cooling effect. It is a substance that easily absorbs heat to become a gas and releases heat to become a liquid. Based on the working method, refrigerants can be classified as primary or secondary refrigerants. According to material properties, they can be categorized as natural or synthetic refrigerants.
When it comes to adding refrigerant to the BMW 5 Series air conditioning system, with over a decade of experience in car repairs, I can say these high-end vehicles require meticulous handling. The exact amount in grams depends on the model year—for instance, older models like the E60 might need around 500 grams, while newer G30 models using eco-friendly R1234yf refrigerant typically require 650-700 grams. However, the quantity isn’t fixed; overfilling can burn out the compressor, while too little leads to poor cooling and wasted energy. I always use precise gauges to measure pressure and avoid system leaks. The refrigerant type must also match—R134a was common in older models, while R1234yf is now the standard. I’d advise against DIY attempts, as the AC system is complex, requiring professional equipment for vacuuming and refilling. A single mistake could cause serious issues—safety first! It’s best to visit a 4S shop or certified repair center. The manual usually specifies the recommended amount in the AC section, and regular maintenance can even improve fuel efficiency.
