What is this tube on the diff?

[coyote550]

I was under my car today doing some exhaust related work and there is something on my Torsen diff that I haven't seen on other S550. A tube or hose coming off the diff. Is that a diff cooler? If it was it doesn't make sense as there should be 2 lines then.

Is that a temp sensor maybe? It you pinch the hose does it feel like wires are inside it?

You don't have a diff cooler. That would look like mine. To the left of the diff cooler line... there is an electrical connector. I think the other post is right that's your temp sensor.

Thanks for the advice guys. It is indeed a temp sensor. Since there doesn't seem to be a way to read it in the car I assume its a safety thing (i.e. limp mode if diff overheats or similar).

I was under the impression that the temp could be read from the dash.

I believe that's on the 18+ with the digital dash.

Why the heat wrap in that area on the exhaust?

Same reason he has a diff cooler. To keep diff temps down

No heat shield in that area. Car goes to the track 4 days a year. Trying to keep the temps down during June to September Florida heat.
