VW and Audis that use G13 coolant have a "mit silikate" printed on the expansion tank.
What that means is that there is a Nylon/plastic mesh bag filled with silicate beads
located in the right side of the expansion tank. These bags have been know to fail and
the silicate beads flow through the cooling system causing all kinds of trouble but mostly
clogging the heater core. People report over a $1000 in repairs if this happens.
Why would Audi think adding this bag to release silicate into the cooling system necessary?
This bag is almost impossible to see if you look into the tank because it takes on the color of the coolant.
It seemed like the down side was a lot greater than any possible gains so I removed the bag.
Any thoughts on why this would be the wrong thing to do.
