BMW B47 ENGINE REBUILD
BMW B47 2.0 Engine Failures
The BMW B47 2.0 diesel engine has similar issues to the N47 engine. So the B47 engines suffer from timing failure also. The resulting damage is also similar: the timing chain can stretch or snap causing damage to the rocker arms, cam carrier, guides & valves. Some of these examples are engines that have not been maintained with regular oil changes. Because of this these cases can be more severe and we have seen crankshaft failure and spun bearings. More often we see the plastic timing guides leave behind small fragments. They make their way down and can block oil feed and galleries, therefore causing turbocharger failure. Because of this like most engine failures it can cause multiple following failures in the form of oil starvation etc.

BMW 2.0 DIESEL ENGINE
The B47 engine was released in 2014 as the replacement for the previous N47 platform. This was released as a 2.0 variant known as the B47D20, this platform was designed to be modular and adaptable for various applications. Produced with 114hp, 148hp, 168hp, 202hp, 221hp & 228hp.
We consider the B47 engine to be repairable due to the nature of the failures that occur. It is more common for an engine surcharge not to apply, especially in the case of timing failure. A complete engine rebuild is very conventional and we commonly work on this engine here at Dieselheads.
