This part cross-references 03F919501A and TS5884 for the same application.

Common Issues This Part Can Address

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting or rough idle related to temperature input errors
• Cooling fan operation that does not match engine temperature
• Rich or lean fuel control caused by inaccurate coolant data
• Check engine light concerns tied to coolant temperature sensor faults

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. The TX274 uses a bolt-on attachment method with a female round plug-in connector and male blade terminals, so matching the original sensor configuration is important for proper fitment. Confirm the vehicle application against the listed fitment for Volkswagen Polo, Virtus, Atlas, Atlas Cross Sport, Jetta, Arteon, Golf, Saveiro, and Audi A8 Quattro models before replacement.
