Sanden PXE16 Air Conditioning (Aircon) Compressor – Volkswagen

Air Conditioning Compressor Issues
The air conditioning unit on various Volkswagens have been known to commonly fail. The Sanden PXE16 air conditioning compressor (aircon pump) is fitted to many of the Volkswagen cars, and many customers have complained that when it fails, there is rarely any warnings whether that be on the dashboard, or any change to the sound of the engine. They have noticed the fault only when they go to turn on the aircon and realise that there is no cold air coming through the vents.

Reason For Common Pump Failure
Having investigated many faulty Sanden PXE16 air conditioning compressor units, we have concluded that the main reason for the failure of this particular unit is due to lack of lubrication within the mechanical unit and that is it most likely down to a manufacturing defect. This is due to the fact the aircon pumps rarely just fail, there is always a root cause as to why it would just stop working, and in this case, it has proved to a be very costly manufactured defect. Although many dealers have now acknowledged this fault, it is still questionable whether they will replace it under the extended warranty in goodwill.

When an air conditioning unit lacks lubrication, it eventually causes metal fatigue. Over time, this results in the compressor shaft snapping, but unfortunately, if this is not rectified immediately, it then leads to further issues within the pump. The rubbing of the broken shaft causes very fine particles, known as swarf, to break off and get within the whole air conditioning system and causing the pipes, valves and the filters to block up.

Also, due to the nature of the air conditioning compressor failure, it is not as easy as replacing the pump and refilling the aircon gas. The aircon expansion valve (TXV Valve) and dryer unit will also need to be replaced due to it being blocked up from the swarf. The air conditioning system would then also need to be flushed for at least 4 hours to ensure that the swarf residue is removed before fitting the new parts.
