As it says in the title. I can't find information in the handbooks about an actual timing belt interval/mileage.

I assume I need a change (50,000miles, 5 years old) but I can see nothing official telling me what's what.

Can someone point me to any official notes regarding the new model C3 intervals?

Hi

Have you tried the official citroen app for this information?

The original interval was a lot higher, but due to the issues of the degradation of the belt (because it is oil lubricated), the interval has been reduced to 50k miles. Usually it is recommended that a cambelt change is accompanied by a new oil pump, but I'm not sure that is necessary at such an early interval.

The degradation causes the the belt to flake bits off. Those bits clog the oil filter screen and cause premature wear to the oil pump and other components.

If you are interested I highly recommend this video HERE. It's in Russian but turn closed caption on and skip the first 50 seconds.
It's a complete tear down of a Puretech engine and why the belt and pump were replaced...and a few warnings.

Another issue is that the ~87bhp cars have (as far as I know) a traditional servo to assist the brakes. As the 110bhp and 130bhp engines are turbocharged there is no manifold vacuum for a servo to tap into. These cars have an engine driven vacuum pump. The material shed from the belt can potentially block the oil supply to the pump causing it to fail, meaning no brake assistance.
