BMW refrigerant filling quantities R134a an 1234yf.
How much freon does my car need?
Most cars hold between 28 and 32 ounces of refrigerant (or about 2—3 12oz cans), however larger vehicles and those with rear A/C will likely hold more. Check your vehicle manual for the system capacity for your specific vehicle.
What type of freon is R1234yf?
R1234yf is a hydrofluoroolefin (HFO) refrigerant. HFO refrigerants are composed of hydrogen, fluorine and carbon atoms, but contain at least one double bond between the carbon atoms. Due to its composition, R1234yf does not damage the ozone layer or has minimal global warming impact.
What PAG oil does BMW use?

Can you recharge R-1234yf yourself?
Can you put 134a in a 1234yf system?
Are r134a and R1234yf fittings the same? Vehicles with R-1234yf have different service fittings than R-134a vehicles to prevent cross-contamination with different refrigerants. Also, it’s illegal to put R-134a or any other refrigerant into a car originally equipped with R-1234yf.
What happens if you mix 134a with 1234yf?
The mixing of R-134a with R-1234yf will change refrigerant pressure and may result in evaporator freeze-up on pressure control systems, reducing system airflow.
How much refrigerant oil should I add?
The AC system in most modern vehicles needs a total of 4 ounces (120 ml) of oil. So, checking the manual is a good idea to be sure of the exact amount and to avoid over- or under-filling the system. A low level of oil may cause compression failure, and overfilling will also hurt cooling performance.
How much oil do I put in my AC compressor?
Most new compressors will take about eight ounces. Make sure the correct oil is used and the amount is used.
How do I know if I have too much oil in my AC?
Inefficient Cooling The most glaring sign of an overfilled AC system is poor cooling because an internal coating forms resulting in reduced heat transfer. For instance, you might notice that it’s taking way too long to cool things or your windows stop defogging properly.
Should I recharge my car AC myself?
The refrigerant shouldn’t escape unless there is an underlying problem. Unless the AC system needs repair, you shouldn’t have to recharge it. Using a DIY AC recharge kit may delay a trip to a professional as the problem worsens or make things worse by overcharging.
How can I make my BMW AC colder?
Why is my BMW air conditioning not cold enough?
One of the most common reasons your BMW’s air conditioner isn’t working is because of an A/C leak. The fluid that is used to cool your car, freon, could be leaking out of your car, or there might be a bigger leak in the A/C system.

How often should you recharge your car AC?
How often should you recharge your air-con? Most vehicle manufacturers recommend that you service or regas your car’s air conditioning system every 1-2 years.
Is R-1234yf being discontinued?
Under an Environmental Protection Agency mandate, R-134a will be phased out and R-1234yf refrigerant must be in all new cars by 2021. The latter is already appearing in vehicles and is “here to stay,” he said.
How long should R-1234yf last?
A/C system service intervals average a minimum of 3 years or 60,000 miles. R-1234yf requires a compatible oil for effective use.
Does R-1234yf cool as good as R-134a?
The results of this study have shown that the cooling capacity of R1234yf AAC system is significantly lower (between 5 to 25 %) than R134a system. In the experiment, the power of the compressor is slightly lower (up to 11 %) for refrigerant R1234yf compared to R134a inside the AAC system.
What are normal AC pressures R134A?
As an air-conditioning refrigerant in newer automobiles, the optimal running pressure for R134A is between 22 and 57 pounds per square inch.
