I thought we'd had people lose the panel configuration after replacing a flat battery, so maybe it's possible to damage it either way. Still, it would make sense to turn on the side lights before disconnecting the battery and turn them back off again after reconnecting. I'd have thought that would drain any residiual charge pretty quickly, though waiting 5 minutes wouldn't hurt either.

Fair enough, there are delicate components inside the dash, but that should have been accounted for in the design. A 12v automotive electrical system is one of the most hostile environments that electronics can be expected to run in, and some extra protection has to be designed in to prevent exactly this kind of thing from happening. I can't think of any other electronic item that's liable to be fried simply by removing and then correctly reconnecting the battery.

This is bad design, plain and simple. Renualt should be providing free replacement for these panels if they're damaged simply by disconnecting and reconnecting the car battery. If the problem affected the rest of Europe, then I bet they'd be doing exactly that as they do with their dodgy turbos. As it is, it's just one more way of getting their own back for Agincourt
