Yep, its one of those engines. Dont think he has the service history exactly as they would want it, to try and claim so he has learnt an expensive lesson by the look of it.
It's in a lot of Stellantis vehicles, Peugeot and the like.
I believe that the 1.2 PureTech engine has now returned to a cam chain over the past couple of years, due to the terrible experiences of the wet belt issues. If truth be told, they only did this as people were avoiding vehicles with wet belts. Even meticulously maintained low mileage wet belt vehicles have had the same problems, with oil pump strainers getting blocked, vac pumps getting blocked and Lord knows what else.
I dare say that Ford will eventually be forced back down this route with their EcoBlue wet belt engines, as some of their EcoBoost engines have already returned to a cam chain.
To make a claim I believe that the owner must have:
Full dealer/Indy service history, and an invoice showing a breakdown of oil spec supplied, oil filter spec supplied and a full breakdown of every other part supplied during each service. Not an issue if the services are electronically logged but could be an issue for people with paper copies. Regarding the specific oil, it’s interesting to note that Peugeot themselves changed the oil spec after the wet belt issues came to light, in an attempt to slow down the issues.
