Design, development and variant notes
The N54 uses two turbochargers, direct injection with piezo injectors, double-VANOS and an electric water pump; it does not use Valvetronic. BMW's 'TwinPower Turbo' marketing name should not be read as a universal turbocharger count across different engines.
The initial 225 kW version and later higher-output applications have distinct calibrations. Alpina also produced modified versions with changes including cooling and internal components.

Additional technical and variant notes
Wikipedia records US high-pressure fuel-pump failures and a recall announced in 2010 for affected 2007–2010 production vehicles. It also describes historical US warranty extensions for fuel-system and wastegate issues; those historical terms do not establish current eligibility.
