  1. Here is some research I did when looking at N54B30xx 335 tourings.

    * Both Turbos, Do they exhibit turbo waste gate chatter, If so is it the waste gate actuator valve and or turbo spindle. This is a large repair if it would happen and is a common fault on all N54B30 engines 60-80ks
    * Coils have they been replaced, when
    *Plugs have they been replaced, when
    * Injector faults
    * Sump leaks, gearbox and diff leaks
    * Electric water pump need replacing every 50-60ks
    * High Pressure fuel pump replacing every 50-60ks
    * Oil in the intake, sooty plugs and intake manifold .. needs cleaning with walnut and vaccum.
    Awesome engine and performance, however do come with the issues that go with it.
    BMW ditched the N54 in place of the N55 single turbo design from about 03/10. Lots of design changes to fixes some of the first gen issues.
    My experience with pre-purchase inspections hasn't been good. Most will just tick the boxes and charge you the $160-200. Something I could have done myself.
    BM Workshop is the source of great information and Ross @ Botany really has had the experience to I think comment on these car now. The other dealers tech departments usually leave it up to the lackies to do the PPIs which is why I think the quality of service over the last few years has dropped.

    Cool, that's exactly what i was after thanks for the info hybrid. Is the hpfp covered under the recall issue or is just safer to replace now? Reading around it also looks like the Injectors are under recall as well.

    Looking to get the PPI done at BM workshop in grey lynn. Will mention the above

    Thanks Again
