Quick facts
- Part: Beck/Arnley 158-0784 coolant temperature sensor
- Also called: engine coolant temperature sensor
- Fits: the 2002-2005 Audi A4 V6 3.0L, the 2002-2006 A4 4-cylinder 1.8L, the 2005-2020 A4 4-cylinder 2.0L, the 2006-2008 A4 V6 3.2L and other vehicles
- Condition: New
A failing engine coolant temperature sensor can show up as a temperature gauge that reads wrong, a check engine light or a hard cold start. A damaged connector or wiring can look much the same, so these signs alone do not prove the sensor is at fault.
Fits
Listed for a wide range of Audi, Volkswagen and Porsche models, it is a coolant temperature sensor replacement for the 2005-2020 Audi A4 4-cylinder 2.0L, and a coolant temperature sensor for the 2006-2013 Audi A3 4-cylinder 2.0L and the 2001-2018 Volkswagen Jetta 4-cylinder 2.0L. It matches OE form, fit and function.

Yes. Beck/Arnley 158-0784 is listed for the 2001-2018 Volkswagen Jetta 4-cylinder 2.0L, one sensor per car. For a different year or engine, look up your own car in the "Vehicles it fits" section.
Is this the right temperature sensor for the 2002-2006 Audi A4 4-cylinder 1.8L?
Yes. Beck/Arnley 158-0784 is listed for the 2002-2006 Audi A4 4-cylinder 1.8L, and that engine takes one sensor.
Are the terminals on Beck/Arnley 158-0784 corrosion resistant?
Yes. The terminals and coatings on this coolant temperature sensor are corrosion resistant, and the sensor is built to withstand an engine environment.
Can I inspect the connector on a coolant temperature sensor myself?
With the engine off and cool, you can look at the connector and wiring for corrosion, cracks or looseness. Testing the sensor's readings is a job for a shop.
Does Beck/Arnley 158-0784 replace OE number 06A919501?
Yes. 06A919501 is on this sensor's interchange list, along with 06A919501A and WT7257.
