2003 modified timing chain

[simlock]

Hi, i am about to replce the timing chain my Daughters vw polo 2003, seems it's common that these chaines slip, which this one did, the next day after we bought it, just wondering if anybody knows what the modification that they did to the new version of timing chain kit??. as there are one on ebay, good brands that are modified kits, but when you take the model number from that listing, it show an identical kit, but there is no reference to it being modified, alos, it would be good to see if the existing slipped one was a modififed kit too.

The tensioner is what was modified. Only buy genuine, febi or gates
