[Update] Looked in the coolant tank at lunchtime and there is hardly any coolant left. Car is going to Brecht first thing in the morning but in the meantime I will top it up with something. Grrrrrr.
Drove the car out of the garage on Sunday to give it a bath (the rain on Friday had made the car filthy) and noticed some fluid on the ground where it had been standing. Scooped it up with a paper towel and it appears to be blue, possibly green, and feels oily rather than like water. This morning when I left for work there was a tiny spot so my hope that it wasn’t coming from Carrie appears in vain. A little web research suggests the fluid is either windscreen washer fluid or coolant but I suppose I’ll take her to Brecht as soon as they can see her.
Only 5.5k miles left on the warranty, soon be time to get all the little annoying things take care of while I can.
