BMW N47 Engine Rebuild

Common Mini 1.6D Engine Failures (N47)

The Mini 1.6D engine is a BMW N47 platform known as the N47C16. We commonly work with this at Dieselheads, these engines are prone to a number of failures in all configurations.

The N47 engines commonly suffer from timing failure, in these cases the timing chain stretches or snaps causing damage to rocker arms, cam carrier, vales and guides. Occasionally we have 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. In this instance the plastic timing guides leave small fragments which make their way down and can block oil feed and galleries, therefore causing turbocharger failure. Like most engine failures this can cause multiple following failures.

Engine History

The BMW N47 engine was first released in 2007, this was used to replace the existing M47 platform. The N47 was produced in 1.6 litre and 2.0 variants with single and twin turbocharging all with varying power outputs for different models. These were fitted to various BMW vehicles but adapted for use in the Mini range. This replaced the existing PSA diesel engines used at the time.

Although the N47 engine is prone to failure we do praise it’s reparability. Unlike many engines we have seen the N47 is more likely to be repairable and it is less common to encounter a bottom end failure causing engine block damage. This means an engine surcharge is less likely to apply.
