Vemo V10-72-1491 Exhaust Gas Temperature (EGT) Sensor

VEMO Exhaust Gas Temperature Sensor for OE Applications

The Vemo V10-72-1491 is an exhaust gas temperature (EGT) sensor built for pre-catalyst monitoring in select Audi applications. It uses a D-shape connector, 2 poles, and an L-form sensor body with an integrated cable for OE-style replacement service.

Built to match OE number 4H0 906 088 AF, this VEMO sensor is specified for high-temperature exhaust environments and supports accurate temperature feedback ahead of the catalyst. It is a direct-fit option for Audi A6 Quattro, A7 Quattro, A8 Quattro, and Q5 models listed below.

Detailed Description

The VEMO V10-72-1491 exhaust gas temperature sensor is engineered for vehicles that require precise exhaust temperature measurement before the catalyst. Its OE-number match to 4H0 906 088 AF and 4H0 906 088 L makes it a practical replacement choice for drivers servicing Audi A6 Quattro, Audi A7 Quattro, Audi A8 Quattro, and Audi Q5 models. The sensor’s L-form design, D-shape connector, and M14 x 1.5 thread help support proper fitment in the exhaust system while the wide operating range handles demanding thermal conditions.

VEMO is the brand line used for OE-style replacement components, and this V10-72-1491 sensor follows that approach with application-specific dimensions and connector design. If you are searching for an Audi A6 Quattro EGT sensor, Audi A7 Quattro pre-catalyst temperature sensor, Audi A8 Quattro exhaust gas temperature sensor, or Audi Q5 OE replacement sensor, this part number should be matched carefully to the OE reference before ordering. This part cross-references OE numbers 4H0 906 088 AF and 4H0 906 088 L for the same application.

What It Helps Address

• Fault codes related to exhaust gas temperature sensing
• Incorrect temperature readings before the catalyst
• Emissions system monitoring issues
• Driveability problems tied to exhaust temperature data
• Replacement needs for a damaged or aging pre-catalyst sensor

Installation Notes and Tips

Confirm the OE number, connector shape, thread size, and sensor location before installation. This sensor is specified for pre-catalyst use, so verify the mounting point on the exhaust system and compare the existing harness length and routing to the V10-72-1491. Because exhaust sensors operate in high-heat conditions, inspect the surrounding wiring, connector, and mounting threads during service.

Quality Assurance

VEMO supplies OE-style emission control components with application-specific fitment details and temperature-rated construction for demanding exhaust environments. Match the part number and OE reference to the vehicle listing for proper application control.
