AC Compressor 5Q0820803P for Audi A3 VW Tiguan | 6SES14C

How we label data. Confirmed values are read from supplied stock and published technical data; reference values are published cross references and are shown for identification only; anything not published is withheld rather than guessed.

An air-conditioning compressor is the pump of the A/C loop: it compresses low-pressure refrigerant vapour and feeds it to the condenser so the heat can leave the car. On the Volkswagen Group MQB platform the compressor is bolted low on the engine block and driven by the accessory belt, with displacement regulated by an internal control valve rather than by cycling the clutch on and off.

The 5Q0820803P compressor is the VW Group reference for the 6SES14C unit. Published parts data identifies it as a Denso 6SES14C compressor: 12V clutch, R134a refrigerant, ND-8 oil, a 6-rib pulley of 110 mm and a bolted mounting. It is listed for the Audi A3 1.4T, VW Tiguan 2.0 TSI and the wider MQB family covering Golf, Jetta, Arteon and Taos, together with the Skoda and Seat models that share the platform.

The EA211 and EA888 engines named in this listing are the two four-cylinder families that dominate this platform: EA211 is the 1.4 TSI unit, EA888 the 2.0 TSI. Because several compressor variants were fitted across the same model years, the safest identification is the number on the old compressor plus the engine code. We confirm the match in writing before quoting.
