D3 vs D4 Alternator life?
Is it correct to say that the SDV6 D4 alternator lasts longer typically than the TDV6 D3 version?

My D3 failed at 42k miles. Took the battery with it.

Higher spec models will chew it up faster than lower spec or base. Particularly heated seats, steering, window elements, etc.
More toys = more power consumption = shorter life span. A poor battery will kill it pretty quickly too. yµ (idµ - eAµ) ψ=mψ
