I have a 184 TDI FR. Specialist VAG garage removed my silica bag during service last year, after advising me that they can split and cause blocked heater matrix and expensive repairs. Just remove the bag and forget about it.What does it seem like the general consensus is to this issue, are people taking this bag out to prevent issues and changing coolant more often or assuming the people that designed the engine know what they’re doing? Is there any chance of a contribution out of warranty if something goes wrong? I’ve just checked my 2016 184 and it has the bag.
