Lines under seat badge?

[Luke20]

Looking on pistonheads it seems some 172 seats have coloured lines under the little embroided renaultsport badge on the seats and some have white lines,whys that then?

 

[B7JLS]

Not sure, but I think the coloured lines are from a ph1 and white line from ph2!

Yeah the upholstery changed on the seats, the newer Ph2 come with a webbed looking effect on the lower back and bottom part of the seat, I assume this was because the alcantara use to fluff up pretty bad after a while seeing as your @rse and back rubbed on the seat in these areas the most
