Do not know if it gets really cold where you are. my wifes 2000 tdi that stayed out of the heated garage started reliabily to -25 farenheit and never failed to amaze me. May have been capable of even colder starts but thats as low as we ever seem to go here. Unfortunatley she totalled the car last august when the tie rod broke in two. Never once refused to start in the three or so years she had it.
