Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 What is the refrigerant type and capacity for the 2004-2010 BMW 528i HVAC system?
What is the refrigerant type and capacity for the 2004-2010 BMW 528i HVAC system?
The HVAC system in the 2004-2010 BMW 528i uses R134a refrigerant. The total system capacity is approximately 700-750 grams (24.7-26.5 ounces). Always refer to the under-hood label for exact specifications.
Q2 How do I reset the HVAC system after replacing components?
How do I reset the HVAC system after replacing components?
After replacing HVAC components, a system reset is required. Use a BMW-specific diagnostic tool (e.g., ISTA/D or INPA) to reset the IHKA (Integrated Automatic Heating and Air Conditioning) control module. This ensures proper calibration and functionality.
Q3 What is the recommended interval for cabin air filter replacement?
What is the recommended interval for cabin air filter replacement?
The cabin air filter should be replaced every 15,000-20,000 miles or annually, whichever comes first. In dusty or polluted environments, more frequent replacement may be necessary.
Q4 Why is my HVAC system blowing warm air on one side and cold on the other?
Why is my HVAC system blowing warm air on one side and cold on the other?
This issue is often caused by a faulty dual-zone temperature control system or a malfunctioning blend door actuator. Diagnose using a BMW-specific scan tool to identify the exact actuator or sensor failure.
Q5 What is the proper procedure for recharging the HVAC system?
What is the proper procedure for recharging the HVAC system?
To recharge the HVAC system, evacuate the system using a vacuum pump to remove moisture and air. Then, recharge with the specified amount of R134a refrigerant (700-750 grams). Use a manifold gauge set to ensure proper pressure levels: 25-35 psi on the low side and 150-250 psi on the high side.
