I've never heard of an EGR valve that can't be cleaned.
Interestingly genuine parts are often not the same supplier as the original equipment, their parts people source parts from different places. No idea who makes them Nissan ones, probably Denso.
You can buy EGR valves from 60€ all the way to €500. I've often found the cheap eBay products are not great, but worth a try...
You need to to double check the right one as they changed Euro 3,4 and 5.
