As I spent a good couple of nights last week replacing the clogged heater matrix and coolant valve on my daughters high mile Mk7 Tsi - likely caused at some point in time by a split silica bag judging by some of the cack I flushed out the system - I decided to pull said bag from my own GTI as the car is approaching six years old. I would sooner replace the coolant every few years than risk the possibility of that bag splitting at some point and again dealing with the known hassles it causes.
That being said....the bag that came out seems to be very robust and I'm not sure how they do split......my best guess would be heat cycles over a long period of time can weaken the plastic mesh material they are made of.
