Global Parts 1712090 HVAC Pressure Transducer

HVAC Pressure Transducer for Audi Applications

Global Parts 1712090 is an HVAC pressure transducer that sends pressure feedback to the engine management system so the A/C control strategy can respond correctly. On modern vehicles, the ECM manages the air conditioning system; on earlier systems, this type of switch can directly shut the compressor off to help prevent damage.

Compatible with select Audi A4, A6, S4, S6, S8, and A8 Quattro applications, this part number 1712090 is a direct-fit service component for pressure-based HVAC control.

Key Features

• HVAC pressure transducer for A/C system pressure feedback
• Supports ECM-controlled air conditioning operation on modern vehicles
• Used in earlier systems to help protect the compressor from unsafe pressure conditions
• Fits select Audi A4, A6, S4, S6, S8, and A8 Quattro models
• Global Parts part number 1712090
• This part cross-references Four Seasons 37372 for the same application.

Detailed Description

Global Parts 1712090 is built for vehicles that rely on pressure signal input to manage HVAC operation. In Audi A4 and Audi A6 platforms, as well as S4, S6, S8, and A8 Quattro applications, the transducer helps the control system monitor refrigerant pressure and respond appropriately. The part number 1712090 is also referenced by related aftermarket listings for the same service position.
