Ahh, brilliant, thanks @Mikey. Regarding the stop start, I'm pretty sure it hasn't been working since I bought the car in 2016. Is there a way to reset or re-enable the stop start to see if it's been disabled for another reason? It's a good bet that I have buggered it. Do you happen to know where I could buy the sensor and where abouts it sits in the car? (EDIT) I've just googled it, I know where the sensor is now
