Mein Auto: F02 (750Li)
Funny i came across this , they Told me $285 bucks to swap the lower radiator hose on my 750LI .. I have just replaced the hose ($35 bucks later ) and still leaking , I Knew for sure the dumb A$$ tech i spoke with was wrong as i told him face to face it can't be the house and could very well be the sensor O ring . Thanks for the info guys .

I'll stop by later today and give you one Superhart, since you live about 3 minutes away... All you have to do to replace it is unclip the temperature sensor from the wire harness and lift it out of the top of the engine bay. Remove the old O-ring and place this one on there in its place. No leaks ever again! You should have called me yesterday before you did all of this because I would have given you the hookup!

So Home Depot has these O rings ? I need to pick one up in a bit or should i just buy the sensor from BMW Tomorrow ?
Thanks again fellas
