You don't need to replace the clip. The high temperature grease is enough to stop the rattle and stop it from seizing. My son has a 2017 Ibiza which suffered a seized rod, I'm guessing four years ago. I worked some grease into the ends of the linkage and it's been fine ever since.When refitting the rod/clip I would suggest using some high temperature paste/anti seize - as they can seize solid, common on the 1.4's to seize and stop the waste gate working.
Maybe they made the later version looser - so less chance of it seizing - at the expense of more chance of it rattling
My car is a 1.4 tsi. Not had a seizure but the linkage did rattle. The grease stopped the rattle and it hasn't returned. Again, that was four or five years ago. I intend to add more grease once a year but I've forgotten about it and never done it.
You don't need to remove the clip or even be looking at it. Just put a rubber glove in and work some grease into the linkage with your fingers. Too much won't do any harm. You want the correct Loctight grease and it's expensive but totally worth it as the problem is solved.
