We've been working on getting my kid's A4 18.T on the road, changing plugs, VC gasket, timing belt, serpentine belt, tensioners, rollers, etc etc, and have come across a cable in the engine compartment that I cannot figure out.
I believe it was disconnected when we got the car, and it has a number on it: 4B1.971.321.
I searched and can only find one website where it's referenced, and it's some guy asking "where the heck does this cable go!?". He got some answers. In spanish....
Can anyone help me out on this cable? Is it supposed to be disconnected, or does it have a home?
Any help is appreciated!
