BMW F30 i3 i8 Electric A/C Compressor 6452-6998209-01 - Used Original Parts

Diagnosis and Common Symptoms

From the workshop floor, failure of the high-voltage A/C compressor is definitive. The primary symptom is a complete and sudden loss of air conditioning, often with no prior warning. The system will not engage, and you will get ambient or warm air from the vents regardless of the temperature setting.

On diagnostic scans using ISTA-D or equivalent tools, you will typically find specific fault codes stored in the IHKA (Integrated Automatic Heating/Air Conditioning) module. Common codes pointing directly to a failed electric compressor include:

• 801222: A/C compressor: switched off due to excess pressure in refrigerant circuit.
• E7140C: Signal (status, electric A/C compressor) invalid.
• 20A908: A/C compressor: Shutoff due to overtemperature.

Visually, there are often no external signs of failure. The fault is internal to the compressor's electronics or electric motor, a common issue as these high-voltage units age.
