This applies to every car fitted with the N54 engine.

In the X6 xDrive35i (N54B30O0), BMW quotes 225 kW and 400 Nm. It was fitted to the 135i, 335i, 535i, X6 xDrive35i, Z4 sDrive35i and 740i among others; in Europe, ADAC lists it in the 135i Coupé from 11/2007 to 02/2010.

High-pressure pump and wastegate: US measures

Two BMW of North America measures apply in the United States and do not automatically cover a European car. In October 2010 a voluntary emissions recall covered the direct-injection twin-turbo sixes of model years 2007–2010 (335i, 135i, 535i, X6 xDrive35i, Z4 sDrive35i) for high-pressure fuel pump failure: long cranking, engine warning light, sometimes reduced-power mode; remedy: new pump and/or software update. In June 2013, following a court settlement, warranty on the turbocharger wastegates was extended to 8 years or 82,000 miles. A slight wastegate rattle is considered normal; a repeated clanking on deceleration from about 3,500 rpm warrants diagnosis. In Europe, have campaigns checked by VIN.
