Hey guys,

Just wondering if anyone here has heard about the silica bags inside the coolant tanks causing issues?

I'm on a couple B8 Passat groups on Facebook and it seems a few people have had issues with the silica bags bursting and the crystals causing all sorts of issues with the coolant and heating system.

People are saying VW should of recalled them but are refusing to take responsibility. A quick google brings up a heap of threads about issues that seem to affect VW, Skoda, Cupra, Audi, etc. The general consensus is to remove the bag or replace the tank to the new design that doesn't use the silica bag.

I had a quick look at mine and it seems to have the bag in there, the only downside I can find is that it will require you to flush your coolant more regularly (approx every 2 years) as the silica adds life to the coolant so it requires less flushing.

Just wondering what people on here think, as I couldn't find on the site.
