Where did you get that from ... because it's news to me.
The only EU regulations I'm aware of in relation to warranties aren't actually about warranties at all, but about the time period within which you can bring a legal action ... i.e. the equivalent of the time period under which you can bring Sale of Goods Act cases in the UK. Here, it's 6 years (5 in Scotland,
IIRC), but across the EU there was a wide variety.
So the EU stipulated it at two years.
Since, I've seen a lot of people talk about two-year EU warranties, but that
isn't what that directive said. It's merely the minimum period within which you states must allow people to take court action, but there's nothing in that Directive that said it can't be longer than that ..... and since the UK already exceed it, it made NO difference here.
If there's something from the EU that prevents a manufacturer offering
additional coverage to that that existing consumer law provides, it's certainly news to me. So if there is something, I'd like o know about it.
