Twin turbo version

In October 2007, BMW introduced a twin sequential turbo model. With 204 bhp, it is the first production diesel on sale to achieve a specific output of over 100 bhp per liter. It uses the same turbo technology first shown in the E60 535d.

This engine is on sale in the E81/E82/E87/E88 123d and the E84 X1 xDrive 23d. This is the engine, which won the International Engine of the Year Award 2010.

Timing chain problems

The N47 engine family is prone to excessive timing chain wear and premature failure.Rattling noise from the rear of the engine is indicative of the condition. Timing chain failure may call for engine replacement or a costly repair. The issue applies to all applications and power variants of the engine produced from 01.03.2007 to 01.03.2013. The most seriously affected units which require the most extensive repairs were produced from 01.03.2007 to 05.01.2009.

Other issues

The return spring on the turbo's waste-gate was not originally lubricated or covered, this frequently resulted in early failure causing the waste-gate to remain partially or fully open. With the subsequent loss in compression, fuel consumption increased by 30%-50%. The problem was described by BMW engineers as a "known fault" and was immediately repaired (BMW mobile engineers even carried boxes of an improved spring), however BMW refused to compensate customers for the excessive fuel consumption and denied this fault was their liability.
