Product Details

This HVAC pressure transducer monitors refrigerant system pressure and sends an electrical signal to the vehicle’s climate control or compressor management system. On Audi platforms such as the A4, A4 Quattro, A6, A6 Quattro, and S4, the correct pressure signal is critical for stable A/C operation, compressor protection, and proper system cycling. Four Seasons 37372 is built as a direct-fit replacement for the listed applications and cross-references Global Parts Distributors LLC 1712090 for the same application.

Use this pressure switch when servicing an Audi A8 Quattro, S8, RS4, or Allroad Quattro HVAC system that requires the specified transducer style and M10 x 1.25 threaded connection. The Four Seasons 37372 part number is also referenced in OE-style interchange listings for multiple Audi platforms.

What It Helps Address

• Inaccurate refrigerant pressure readings
• A/C compressor cycling problems
• Compressor shutdown caused by pressure signal faults
• HVAC system fault codes related to pressure transducer input
• Loss of cooling performance from a failed pressure switch

Installation Notes

Verify connector shape, terminal count, and thread size before installation. This unit uses a female M10 x 1.25 fitting and is system mounted, so the replacement should match the original sensor location and electrical interface exactly. Confirm the vehicle’s HVAC diagnosis before replacing the transducer, and inspect the connector and sealing surfaces for damage or contamination during service.

Quality Assurance

Four Seasons lists this pressure transducer as meeting or exceeding OEM requirements, supporting OE-style fit and function for the specified Audi applications. Part number 37372 is engineered for direct replacement use in the HVAC pressure control system.
