Silica bags in coolant housing???

[Oldwestern]

Hi,
I have a 2014,C4 Grand Picasso, manual, diesel in which the front blower & heater has packed up. Rear blower still works.

Just seen YouTube vid of guy explaining that VW & derivative makes & models plus other makes & models, of around the era of my car, were often fitted with silica gel bags within the coolant expansion tank.
See:

My questions, about which I am keen to receive a knowledgable response, are:-
1) are such silica bags to be found in Citroen C4 Grand Picassos?
2) If so, are the bags known to split & cause a problem?
3) How much of a problem can it be?
4) … and how expensive?

Thank for reading this far and TIA for your responses.
Cheers,
Oldwestern.

This fiasco does not affect PSA vehicles to the best of my knowledge - it's VAG issue (Skoda, Audi, VW etc.).

Thanks, GMAB, but… PSA?
Ok, looked it up and understand - stupid boy

Yes, I was specific to say PSA (as they were) to mean Citroen Peugeot & DS Automobiles as the new Stellantis group is far more encompassing now being that they currently include Abarth, Alfa Romeo, Chrysler, Citroën, Dodge, DS Automobiles, Fiat, Jeep®, Lancia, Maserati, Opel, Peugeot, Ram & Vauxhall. So I can't be 100% sure that the silica incident does not include any of the other brands mentioned.
