Hi there, I have a longer ratio diff off a 320 to use on my 318. Will this require a new speedo sensor? If so where is it located? Thanks in advance, Dan.

No mate, your speedo drive is from the gearbox.

meaning you need a different speedo as the correction is built in there, otherwise it will never know what final drive is fitted. See under top tech topics.
