🔧 Mechanic's Notes
- Same N54 hit list as the 335i: HPFP long-crank/limp episodes — verify whether the pump was done under the extended campaign.
- Cold-start wastegate rattle means actuator bushings are on the way out.
- Carbon buildup on the intake valves is a when, not an if — walnut blast every 60–80k.
- At higher miles, valve stem seals show as smoke after long idles; diagnose properly before blaming turbos.
Field patterns from a working mechanic — diagnose your own car before buying parts.
