Exact same problem as OP posted with stalling on cold engine within approx. 1 mile (if not much much sooner). Replaced EGR valve yesterday and it seems to have gone away. Rough idle has also mostly smoothed out and van just drives more smoothly and responsively overall. Also, my MPGs had been way down for a long long time, like 13-15mpg in mixed hwy/city driving. Upon replacing EGR I drove home in mixed driving (albeit more hwy than city compared to our 'normal' driving patterns) and got 20.7 mpgs driving home from having the EGR valve replaced.
Pros: smooth idle, responsive driving
Cons: temperature issue remains
Vehicle:
Volkswagen
