Is the fresh water tank BPA free plastic?

[Hannick]

I think it is very unlikely the fresh water tank in the California has been manufactured as BPA free but I would like to know.

BPA is increasingly being eliminated from plastic water and drink bottles and we avoid it wherever possible. I see Thermos have made a commitment to now only supply BPA free containers. They say "Bisphenol A (BPA) is a controversial chemical that can be found in the lining of food cans, certain water bottles and more. Some researchers have linked the hormone-mimicking chemical to a host of issues including behavioral and developmental effects in kids. Thermos plays it safe, and has made a commitment to only manufacture products that are BPA-free."

I asked the dealer but just got a blank look.

Still, it matters to us and at the risk of sounding like a loony we don't drink water stored in the tank, we just use it for washing etc.

I wonder how we can find out? Anyone know? The dealer thought a call to VW was a waste of time.
