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.

Other issues

The return spring on the turbo's wastegate 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 boost, fuel consumption increased by 30–50%.
