BMW F10 F11 N47D20 How to Remove AC Compressor 520d 2011-2017

Replacing the AC compressor on a BMW with the N47 engine is a precise job. Since this engine is found in a variety of chassis (E90, E60, F10, F30, X1, X3), space can be tight, but the process remains largely the same. ​Here is the technical breakdown in English: ​🛠️ Step-by-Step Replacement • ​Refrigerant Recovery: Use an AC service station to vacuum out the old gas (R134a or R1234yf). Do not vent it into the air; it's illegal and bad for the environment. • ​Drive Belt Removal: Use a T60 or T55 Torx (depending on the tensioner version) to rotate the tensioner pulley and slip the belt off the compressor pulley. • ​Electrical & Line Disconnection: * Unplug the control valve solenoid connector. • ​Remove the bolts holding the high and low-pressure aluminum lines. • ​Tip: Plug the open lines immediately with caps to prevent moisture from entering the evaporator. • ​Compressor Removal: The unit is typically held by 3 long bolts. On the N47, you may need to move the intake charge pipe or some plastic shielding to get enough clearance to pull the unit out. • ​Installation: Bolt in the new unit, reconnect lines with new O-rings, and reinstall the belt. ​⚠️ Critical Success Factors ​1. The "Black Death" Check (Metal Shavings) ​If your old compressor failed internally (seized), it likely sent tiny metal shards throughout the system. • ​Action: Inspect the orifice tube or the expansion valve. If you see "grey sludge" or glitter, you must flush the entire system and replace the condenser. Otherwise, the new compressor will fail within days. ​2. Receiver-Drier Replacement ​The drier acts as a sponge for moisture. Once the system is opened to the atmosphere, the drier becomes saturated quickly. Always install a new one during a compressor swap to protect the internal valves from corrosion. ​3. Oil Balancing (PAG Oil) ​New compressors often come pre-filled with oil, but never assume it’s the correct amount. • ​Drain the oil from the old compressor into a measuring cup. • ​Drain the oil from the new compressor. • ​Refill the new compressor with the exact amount specified by BMW (usually around 100\text{ml} - 150\text{ml} total system capacity, but check your specific VIN). ​4. Vacuum Test ​Before charging with gas, the system must hold a vacuum for at least 20–30 minutes to ensure there are no leaks and to boil off any remaining moisture. ​💡 Maintenance Tip for N47 Owners ​While the belt is off, check your Crankshaft Pulley (Harmonic Balancer). The rubber inside the N47 pulley often cracks. If it wobbles, it creates vibrations that will destroy the bearing on your brand-new AC compressor. #automobile ​ #cars​​ #mechanic​​ #mechanicrepairteam​​ #shortsfeed​​ #mechanical​​ #repair​​ #toyota​ #vw​ #volkswagen​ #bmw​ #mercedes​ #carsfix​    Youtube:        / @sevtauto9289          / @petersgarage111   If the video was useful give us “thumbs up” and consider subscribing to the channel to see more videos!
