-25c here this morning and no trouble starting up my VW!
on my 2nd VW (14 jetta and now 19 alltrack) and have had the pleasure of driving a 94 golf, early 2000s beetle, and 2012 eos for extended periods.
all driven in winnipeg where it routinely ranges from +40c in the summer to -40C in the winter and never had any problems!
some scandals aside which did not affect me directly, but im a big fan of their cars.
congrats on your purchase!
