This temp sensor is used to send coolant temp data back to the engine computer. The ECU uses this data to set cooling system performance, as well as fuel and ignition mapping. A bad sensor will send incorrect data back to the ECU and will result in poor engine performance and worse fuel economy. There should also be a corresponding fault code and check engine light or you might notice erratic gauge readings.
This is a Genuine BMW temp sensor with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
