Hi there - was hoping someone slightly more mechanically-minded than me could help. A warning light appeared on the dash of my car last night - it's yellow and is two small arrows pointing at a tiny dot. It has brackets around it and a wiggly line underneath. I've tried googling to find an image like it, but without success (and it's since disappeared from the dashboard). I have the car booked in for a service on Monday but was wondering if anyone could shed any light in the meantime (in other words, I'm wondering if it's safe to drive over the weekend?). Cheers.
