2007 Audi S8 5.2L v10 passenger coolant fan want stop running
 

Does anybody know were the Engine coolant Temperature is located at on th 2007 Audi s8 (Engine code BSM) I replaced the 1 that i can see on the coolant line which is grey but im looking for the Green one 4 prong, I suspect that its bad wherever it is cause the coolant fan on the passenger side turns on 8 seconds after starting the car and even after i turn the car off its still running and then i gotta disconnect the battery then reconnect it but starts up again if i start the car up..i have looked everywhere for the relay to and pulled them all and it stills runs ??
