So you should have gone through and instigated a return through Amazon, as your contract was with them not Sony.
That parts explained in Amazon's returns section on how to go about returning faulty marketplace items.
But seeing as you never, Sony really have no responsibility with your item.
As it stands, they have gone above what they are legally entitled to do.
Your contract was with Amazon./marketplace seller.
And Sony can refuse service if the seller was not an authorised seller/agent.
The pan European warranty exists if the seller was an official authorised seller.
You cite 2 different types of warranty, and unfortunately you can't mix them both.
You can either go to the retailer or go straight to Sony(provided the item isn't an import) but you can't mix them both up.
I think you've shot yourself in the foot by going to Sony with an imported item.
It would be like me buying a TV from Amazon Germany and living in the UK then returning it to Sony Germany, to be fixed. You've gone about it wrongly, the retailer should have been the first port of call.
So your item would be classed as an import and importing carries risks usually due to warranty problems.
At least you'll know for the next time.
