OVERVIEW
Replace the correct original temperature sender
079-919-523-J is the Genuine VW/Audi temperature sensor for the specified original installations. Its sensing probe, two-pin electrical connection and mounting feature match the factory component at the assigned location.
The factory application determines what temperature this sensor monitors. The confirmed installations below include oil-temperature and intake-air-temperature positions, so identify the original sensor number and exact installation point before ordering.
Technical details
- Complete factory number: 079-919-523-J.
- Factory specification: factory two-pin temperature sensor, complete number 079-919-523-J.
- Design: metal sensing probe, molded connector body and mounting tab, as pictured.
- Quantity supplied: one individual temperature sensor.
One individual sensor is supplied. Housing, flange, wiring, mounting fastener, seals and fluids are separate unless expressly part of the pictured sensor. Match the complete original number and mounting arrangement; this is not a universal sender.
Common reasons to replace
- Testing confirms an implausible temperature signal from the assigned sensor.
- The sensing probe or connector body is physically damaged.
- An internal sensor fault is confirmed after wiring checks.
- The original mounting feature is damaged.
Check diagnostic readings, connector condition and wiring using the vehicle-specific test procedure. A circuit fault or actual system temperature problem can produce similar symptoms. Determine the sensor's assigned function before interpreting the reading.
Vehicle fitment
Use only at the specified original sensor position. The table identifies the monitored system for each confirmed application; match the full original number, connector and mounting feature.

Installation guidance
Follow the repair procedure for the exact sensor location. Work with affected systems cool, control any fluid released and renew the specified seals or retaining parts. Keep the sensing tip and mounting bore clean and tighten the attachment as specified.
Verify correct connector engagement, inspect for any applicable leaks and compare diagnostic readings with the expected values. Complete the prescribed fault-clearance and function checks.
