About this part
The air conditioning compressor on your R-Class W251 pressurises the refrigerant and keeps the whole system working. Warm air despite a full charge, a grinding noise from the belt drive or a magnetic clutch that no longer engages all point to a failure.
Frequently asked questions
What should I check when buying an AC compressor for the Mercedes-Benz R-Class?
Manufacturer and part number matter, and so does the refrigerant your R-Class W251 uses - R134a and R1234yf need different oils. Compare pulley diameter, rib count and the connector type of the control valve as well.
Does anything else need replacing with the compressor?
If the old compressor broke up internally, swarf is spread through the whole circuit, so the drier and expansion valve go with it and the lines get flushed. Skip the flush and the new compressor swallows the debris and fails again.
