How to Charge Air Conditioner BMW 5-Series 2004-2010
In this guide, you will find instructions on how to recharge the BMW 5-Series Air Conditioner (AC) with R134a refrigerant (freon).
This guide applies to 5-series from 2004 to 2010 applicable to models such as 525i, 530i, 535i, 545i, M5 520d 530d 535d. Follow the step-by-step instructions below and make sure to watch the how-to video as well.
If your BMW 5-Series blows hot air but no cold air, it may be an indication that the A/C system is low on refrigerant.
What you will need
- AC Recharge Kit
- Safety Glasses
- Start the engine and let it idle.
Ensure your vehicle is in Park.
Start the engine while keeping the vehicle in the park. If your BMW has a keyless start feature with a START/STOP button, press START to start the engine. With the engine running turn on the air conditioner system on your car. Set the temperature to MIN and blower fan to MAX. Make sure the A/C button is pressed or is switched ON.
Pull the hood release under the dashboard. Secure the hood in the up position. Ensure the hood does not fall down on you while you are charging your BMW 5-Series with refrigerant.
Locate the low-pressure air conditioner charging port. Remove the cap from the A/C charging port.
Connect the a/c recharge kit to the low-pressure line. With the engine running take a reading and ensure the refrigerant pressure is the low zone.
Connect the A/C recharge kit, start the car. With the A/C recharge kit connected read the gauge. Continue to the next if the A/C pressure reading is low.
Charge A/C Once you reach the recommended pressure level stop adding refrigerant to your BMW 5-Series AC. Overcharging a BMW 5-Series A/C with refrigerant does not make the air blow any colder and can cause damage to the air conditioner system.
