I need te replace my temp sensor on a 97' A4 2.8Q 12v and on ESC Tuning they carry two parts, Green EC#1484 and Blue ES#2832.
witch one do I need fro my car? or are there 2 sensors?
and where is the fan switch located?

 

look here for all your 12v motor ? 12v stuff

 

jackson, you'll have to look atyour old sensor to see what color you have...it should be either blue, green, or black (if it's black i beliueve you use the green)...check out the ultimate timing belt kit from ecs, it shows you a picture of where the fan switch is...

 

For your 97 12v it will be the Blue one
