Some nonsense there:
VANOS appears only in the non-turbo version of the engine; (the turbo is not in that version either).
Direct injection is in virtually every modern engine design, and this is behind carbon ash build up around the inlet ports, something shared with all other similar makes.
Oil consumption is a turbo engine only problem as the oil comes from the turbo bearing. Even so, many THP engines don't drink oil.
The timing chain failure in early engines was a problem of stretching.
Then the ads begin.
Ceramic lubricants contain minute particles of boron nitride, to coat the surfaces. They have a few industrial uses. PSA engineers and chemists know a bit about lubrication too, and have published an oil spec best suited..
Fuel additive cleaners are wishful thinking, as they have no proved effect on oil ash build up at the ports.
Behind many of the modern developments seen in this engine were the upcoming new EU lowered pollution rules. Makers had to develop new engines without loss of power under these new conditions. Combustion operation was critical. For such an expenditure they actually needed increases in power as engine production runs for years. "Prince", BTW is a BMW code word. Peugeot Citroen don't use it.
