New VW B6 Owner First German Whip aha ! Any good ?

Atm Im enjoying my new B6 however few things im concerned about, my mechanic told me the 2.0 TDI is more unreliable than the 1.9TDI ? also back passanger door does not open when other doors are unlocked it will only open from the inside. Haven't given fuel economy a chance yet but will keep an eye. Something I have noticed though when the car starts slightly shake for 5 seconds or less not sure if this is normal or not :S..... Any feedback would be great man :thumbup:
