In addition, N62 has intermittant shaft lever issues (HUGE $s for repair when they get noisy). When compaired to M62s, many repairs (like valve cover gaskets) require DOUBLE labor hrs to correct, due to additional components/added complexity of items needing removal/replacement. Not DIY friendly, open your wallet WIDE at the dealer/indy.
3.0 also has CCV and DISA valve issues.
