"I own a 2002 Audi 2.7T quattro and the Beck-Arnley coolant temp sensor failed in just 27 days. I started getting false low coolant warnings on a cold engine even though the coolant was completely topped-off. Shortly thereafter the coolant temp needle started creeping into the overheat zone despite showing cool engine temps otherwise. The false overheat condition led to improper rich fuel conditions and horrible mileage as a result. Furthermore the rich fuel running also led to numerous cylinder misfire codes at full throttle. Lastly the false overheat gauge reading compromised correct A/C function simply because the ECU thought the engine was running too hot and shut the compressor off until the coolant needle reached a certain point on the gauge. Audi is very particular about parts. They are designed to optimally run on OEM parts which far exceed what anybody else produces aftermarket. If the coolant temp sensor does not show a VW and four-rings symbols on the part....you can count on them failing almost randomly."posted by: Dilberto on August 27, 2012view all 2 reviews
