One-stop purchase of expansion valve 8W0 820 679 for Q8

The expansion valve is the throttling core of the air conditioning system. Affected by long-term refrigerant impact, pipeline pressure fluctuation, engine cabin high temperature and vibration fatigue, the internal valve core is prone to jamming, scaling and failure of flow regulation. A faulty expansion valve will cause abnormal air outlet temperature, insufficient cooling effect, intermittent cold air, frost on the pipeline, abnormal noise of the air conditioner compressor, and even overload damage to the compressor. Most buyers will purchase this expansion valve together with AC pipelines, sealing rings, filter driers in a single bulk order to reduce purchasing and logistics costs, bringing stable profit margins and low inventory pressure for distributors all year round.

Manufactured strictly according to Volkswagen Group original technical standards: overall aluminum block outline, pipeline aperture size, mounting hole position, internal throttling channel and superheat setting data are completely consistent with genuine 8W0820679. Compatible refrigerant: R134a, with universal interchange performance for related VAG models. No cutting, drilling or pipeline refitting is required during replacement. It is installed between the evaporator and liquid pipeline of the Q8 air conditioning box, perfectly fits the original vehicle pipeline interface and fixed position, greatly shortening air conditioning maintenance working hours.
