BMW N47 ENGINE REBUILD
Common BMW N47 Engine Failures
The BMW N47 engine is a common sight at Dieselheads. They are prone to a number of failures in all configurations.
The N47 engines mainly suffer from timing failure. In these cases the timing chain can stretch or snap and so causing damage to rocker arms, cam carrier, vales and guides. During inspection we have also discovered failed turbochargers on both single and twin turbo variants. Some of these examples are engines that have not been maintained with regular oil changes. More often the plastic timing guides leave small fragments which make their way down and blocks the oil feed and galleries, therefore causing turbocharger failure. Like most engine failures this can cause multiple following failures.

N47 History
Engine History
The BMW N47 engine was first released in 2007 as a replacement for the old M47 platform. The N47 was produced in 1.6 litre and 2.0 variants with single and twin turbocharging and so provided varying power outputs for different models. The 1.6D (N47D16) has a 94hp and a 144hp version. The 2.0D (N47D20) has 114hp, 141hp, 161hp, 174hp, 181hp, 201hp & 215hp variants. So these were fitted to the 1 Series, 2 Series, 3 Series, 5 Series, X Series and various MINI vehicles.
Although the N47 engine is prone to a number of failures we do praise it’s reparability. Unlike many engines we have seen the N47 is more likely to be repairable and is less likely to encounter a bottom end failure incurring engine block damage. This means in turn an engine surcharge is less likely to apply. However, this is only the case if the necessary measures have been taken to save the engine after failure.
