A light's just come on in the dash - a solid circle, surrounded by a broken circle (but with no top or bottom on the broken one). If you see what I mean!
I think it's the brake pad wear indicator, but just need to confirm this with your good selves.
Car's booked in for its 72k mile service next week (ouch!!) so will get the pads replaced then. Might need new tyres as well, so I reckon my flexible friend will be working overtime.
