My car is a 2008 128i with the same wonderful radiator design. I have had EAC code pop up. I cleared it, and a week later it came back. The radiator is fine, so I followed your thread. Thanks, MINIz Guy !

When I ordered a similar BEHRU temperature sensor from a MB dealer online, they contacted me back and asked for my VIN. I explained that I don't have a MB vehicle, but that the manufacturer of my car makes me buy the entire radiator instead of just the part. I said using the MB part was a known repair. The lady's response was "Oh, got it !" and said my part would be here in a couple of days - which it was. I could not find exactly the P/N that MINIz Guy used, but I think the P/N differences are mostly for cable length and connector style. My P/N is 221 905 56 00 A

I add a photo, because I may have discovered why I got an intermittent error. Notice that my sensor popped off the radiator almost intact, and I could see the failed glue still in the radiator block. Maybe this made the temperature response slower, or maybe this had nothing to do with it, but it's all back together, and I will report my experience.
