badly scratched floating floor

Just inspected one of my houses the (very good) tenants are leaving after five years and the floating floor inside the back door is extremely scratched and worn. I think these floors were only cheap and the wood pattern has actually worn off in a couple of small places. I rang a floor specialist who said the only remedy is to replace the boards. I dont think I have any of the same boards and the floor is about 12 years old so probably cant match it. Has anyone tried to repair a floating floor by cleaning the scratches so they are not black and painting the colours back into the worn spots? Maybe I could paint some clear varrnish over the area afterwards. Anyone else had this problem?

 

At 12 years old i'd probably just replace it to be honest - how large of an area is it?

 

Can you get away with just doing that room/area in similar boards?

 

I'd be having a good hard look for the warranty and the purchase invoice. If it gave a lifetime warranty, then I'd be putting it back on the manufacturer. If not, do as per @D.T.

 

spoke to the tenant and he thinks there are some spares in the garage so with a bit of luck, problem solved. I also had a look in Bunnings and they all seem to be the same thickness which was my main worry if I bought new ones, apart from matching the colour as I dont want to replace the whole ground floor
