Audi’s OE coolant temperature sensor, part 078919501B, is a genuine used sensor removed from a donor vehicle. This sensor monitors engine coolant temperature, sending data to the ECU for fuel mixture and cooling fan control. When it fails, symptoms can include poor fuel economy, hard cold starts, or an illuminated check engine light. It was originally fitted to Audi A4, A6, S4, Cabriolet, and Volkswagen Golf and Passat models with 1.8L, 1.9L diesel, 2.0L, 2.7L, and 2.8L engines. A direct plug-in replacement requiring no reprogramming.
