WFC - Working from coffeeshop

I took the car into Renault (again) today for them to have another go at finding the source of the battery drain. In the meantime I decamped to Costa to try and do some work while they checked it out. 
That checking out took all day! But at least they think they've found the problem - a faulty UPC(?), and it is 100% under warranty. Just need to wait for the part to come in now.
