I'm getting 09 - Water Thermosensor - Coolant temp fixed at 176F and I changed the sensor behind the water pump (the connector seems to be loose on it). I'm planning on replacing the coolant temp sensor which seems to have the wire glued to the sensor that screws into the radiator.

I'd like to hear any suggestions as well as see if there's another sensor I missed and if so where they are.

 

By the way it's a s5 NA

 

the one on the back of the water pump is the correct one, connection needs to be tight/good

 

Thanks I'll try to figure out a way to tighten the connection. So what issues does this cause? Is 176 too high for the rotary?

 

176 is low
