BMW B48 2.0 AC Compressor Pump - Used Original Parts

Diagnosis and Common Symptoms

A failing AC compressor on the B48 engine is a common issue that directly impacts cabin comfort and can lead to more complex system failures if ignored. Diagnosis in the workshop often begins with scanning the IHKA (Integrated Automatic Heating/Air Conditioning) module. Technicians frequently observe fault codes such as 801222 (A/C compressor: Shut-down due to missing DME release) or 80120B (A/C compressor clutch: Open circuit).

Common symptoms reported by drivers include:

• Weak or no cold air from the vents, even at maximum setting.
• Intermittent cooling that works for a short period before blowing warm air.
• A noticeable grinding, whining, or rattling noise from the engine bay when the AC is switched on.
• Visible failure of the compressor clutch to engage when the A/C button is pressed.
