Application and Buying Notes

When replacing an air conditioning compressor, the safest check is the part number and the physical layout. This unit is identified as CXS1221 and also carries original equipment number 1221, with an ear mount configuration, 120mm clutch diameter, and 6 groove pulley section. If those details do not match the vehicle’s existing compressor, do not assume it will fit.

The application list covers specific petrol and diesel engine capacities in Audi TT, Volkswagen New Beetle, Golf MK5, and Polo MK3 models. That said, vehicle build dates, bracket arrangement, hose position, and pulley style can still vary, so the engine size alone should not be used as the only guide. The Horizontal Special Pad fitting type and VQL head code are useful checkpoints when comparing the old unit.

This compressor is specified for 12V systems and is listed with SP10 oil and 135ml oil capacity. If the vehicle requires a different oil type or a different charge quantity, the installation should be checked carefully before fitting. A compressor mismatch can create installation issues or system problems even when the vehicle model appears close.

At 7.5kg, this is a substantial component and should be handled carefully during inspection and installation. The unit is supplied without a dust cover, so if the existing installation uses one, confirm whether the vehicle setup expects a separate cover or a different arrangement. Matching the pulley groove count, clutch diameter, and mounting style is just as important as matching the model family.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number CXS1221 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

For part number CXS1221, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

Compatibility note: Confirm fitment using part number CXS1221, original equipment number 1221, the 12V ear mount configuration, and the listed vehicle application details before ordering.
