Engine Coolant Sensor Location 2.8L Z3

So, I'm a bit confused and am looking for help. I just bought a 2000 Z3 with a 2.8L engine and got a P0125 code (ECT Sensor Insufficient for Closed Loop Fuel Control). Whether than testing and deciding on what parts to replace, I have just decided to replace the Thermostat and the ECT sensor. The only problem is, I can't find where the ECT sensor actually is... My car seems fine, I haven't had any problems, the needle is always straight up, no fluctuations (it's a BMW so I look at the temp gauge constantly). I've heard several things from a few other BMW owners about what it could be between the two, so I figure regardless of what it is, having both new parts won't hurt the car any. So, where exactly is the sensor that might be causing the P0125 code?
