My dealer would like to change my VW touran brake fluid every two years. Is
this being over cautious or sensible preventative maintenance?

The latter.

Brake fluid adsorbs water from the air. The water will cause internal
corrosion. In theory, it may also boil, turn to steam, and leave you
temporarily with no brakes, although I've no direct experience of that
happening.

VW suggest 3 years, 30000 miles

Actually, I take that back - if you google search

http://www.google.co.uk/#hl=en&source=hp&q=touran+brake+fluid+change+interval&aq=f&aqi=&aql=&oq=&gs_rfai=&fp=a0f713e140dfbc98

the above link appears about 4 down, and google highlights the figures I
gave.
The linked doc however makes no mention that I can see.
So, at sometime in the past the figures were as quoted, but newest blurb
has deleted this info

Autodata say every two years. Perhaps it depends upon exact year or
something.
Every two years is a very sensible change period.
Old brake fluid can cause problems as the vehicle gets older, the effects
creep up over the years: seized calipers/cylinders and master cylinder
faults being the most common results of failure to change. Could be an
interesting legal question if old fluid caused brake failure and a crash.
fluid change works out at about 30 p per week. (30 quid every two years)
you could save that by driving more economically!!
