Hey there, have exactly the same issue. Took my car to a guy who stated it would cost around $275 to fix ( I’m in Aus) his one concern was the seat covering could be stuck to the foam underneath as apparently is the norm for some other Peugeot models, and he wouldn’t know for sure till he got the seat out to have a look.It’s the side bolster on the back rest the base is fine
hank you so much…such a relief. Exactly, all my other seats are in perfect nick. It’s my daily ride so getting in snd out constantly definitely puts strain on that pointMine separated at the top just like in the photo above. It cost me a couple of hundred Oz dollars to get it fixed. It's a seat out job. He said he's got to be careful to use the right thread because of the side airbag. It has to be able to burst through. It's easy to push there with an elbow getting out.
Wow thanks for posting the picks…puts my mind at ease…looks like a common problem, as a driver you just can’t help but put some weight into the area to get in and out of the low carHad mine fixed here in the uk , if I remember correctly it cost £120 he told me it was pretty straight forward an it was the first modern seat he had done as he normally fixes up 50s an 60 s classic car’s interior’s .
