There is a safety recall (JZR) on the 110/130 Puretech Engines details here.... - Click Here -
on a Peugeot forum

Concerns March 2013 - April 2017 built Puretech 110 / 130 engines.

I was wondering why the issue already reported was limited to 110bhp and above. Seems like the braking assistance is provided by a driven vacuum pump which may clog with the detritus from the belt. Presumably the assistance in non-turbo engines is conventionally powered by manifold vacuum.

Quoting from one of the posts: Depending on the size distribution of the belt debris, belt debris may first clog the oil filter. In that case, the oil filter open its bypass valve without alarm. The oil pressure alarm toggle only if the oil pump strainer is clogged first.
When belt debris enter the pressured oil circuit, they will clog the vacuum pump strainer (which is very small) and kill it.
