French cars are often miss-diagnosed,
they really don't work well with any diagnostic systems other than in this case Lexia diagnostics
,Citroen own system.
And of course this system has to be used by a mechanic who knows what their doing.
All that might be of little help to you but a competent Tech using "Lexia" could acces cam/crank sync and tell "IF" the chain is stretched.
What I'm stating is it's better to pay for a good diagnostic tech to scan it rather than just guessing and buying parts in the hope of hitting the fault.
Try to find a Bosch diagnostic specialist near you.
They are usually well trained.
