Interestingly, I called my local Mini Dealership to find out what they charge for a belt change and the person I spoke with stated that my car will 'definitely be fitted with a chain, not a belt - and that they don't recommend that it is changed without good reason - such as engine noise / rattle'.
When I said I was thinking it may be worthwhile preventative maintenance on my 2010 70k mile car - they said 'no - too young a car, don't even look into it any further'!! And that if there was any undue noises - they'd change the tensioner first anyway!!
Were the late spec (2010) peugeot engines fitted with a chain before the engine changed to a BMW unit then?
above link sums it also bbc watch dog done a bmw shaming of the endless problems with them in their view not just mine,, just sums bmw up head up their backside and pretend there is problems with it, where the internet is full of their n47 diesels and prince engine petrols with chain issues,, i've worked in trade as mechanic for over 35 years up until around 2007 i bought bmw diesel after bmw diesel were epic,, then this stupid idea of mounting the timing chain and a thin chain as well on the rear of the engine so when they wear out its a engine out job made me stop buying them again,, also because its mounted behind the daul mass flywheel that also fail for a past time and when do start to they also rattle many owners get caught out,, ie garage says not to worry sir is the flywheel got loads of miles yet before it needs changing,, to find a little way down the road the chain jumps teeth knocks holes in pistons and smashes the valves in to the head and backs that scrap as well,, yep new engine only way forward, the later engines with timing chains,, the psa engine as a small link chain between the two cam shafts but have a timing belt this would be pre 2010 march anything after should be the n47 bmw own engine ,,
i believe a memo was added to bmw that timing chains should be treated as serviceable wearing part with around 100,000 miles, i know vag group do on all theirs now,,, just stupid on all levels designers using a thin chain thats fairly long that has a lot of loads on it over the miles,, when in old days a duplex chain was used on the 325tds and would last 500.000 miles i know i had one work hack
