When I had my car in 2017 (1.2 petrol) I was given a sheet showing the service schedule - it was specific to my car printed from a Peugeot system as it shows my VIN details, so hopefully a dealer will be able to provide the same info specific to you car. Worryingly when I was recently asked the service department at my Peugeot dealer where I purchased the car from, the people on the desk were quite surprised it was 6 year interval for the timing belt even though I showed her the paper that dealer gave me nearly 6 years ago, as she thought it's normally 10 years. Given my car is approaching 6 years I wonder how much incorrect info had been given on a general enquiry about when the timing belt needs to be changed.
For my 1.2 petrol it says (normal conditions):
ancillary drive belt - 64k miles or 6 years, then every 128k miles or 12 years
ancillary drive belt kit - 128k miles or 12 years
timing belt - 64k miles or 6 years, but then every 128k or 12 years which seems odd, why not every 64k or 6 years if the first change needed that?
timing kit - 128k miles or 12 years
My timing belt has just been replaced under a KGH recall which I found out about in December 2022
I presume the timing kit is the timing belt and water pump but I'm just guessing there. From previous cars (non Peugeot) on timing belt changes I thnk the water pump was done at the same time.
