Any ideas what it is and where it should go? Also, it is the cause of the engine light being on?

    That's an external temperature sensor - an afterthought in some way or other on the ST170 as it's usually just cable-tied to the side of the battery box. Looks a right bodge! Don't see that being cause of the engine light coming on.

    Hope it stays off but will no doubt return at some point I'm sure.
