BMW 520d Engine Replacement and Fitting

A client recently came to us with a BMW 5 series which had suffered from engine failure. His vehicle is a 2008 BMW 5 Series 2.0 diesel and has the notorious N47D20 engine which suffers from common timing chain and tensioner failure between the years of 2007 – 2011.

This issue was so serious it was highlighted by watchdog:

The timing chain links all the moving parts of the engine that work together in order to drive the car forward. They must all work in perfect harmony and unfortunately when a timing chain fails in generally results in significant engine failure.

All BMW 1 series, 3 series and 5 series 2.0 diesels from 2007 – 2011 can potentially suffer from this common problem. If you own a BMW within this range then look out for the following symptoms:

  • Engine misfires
  • Metal shavings found in oil or oil filter
  • Rattling sounds from the engine

Identifying the issue early can save you a hefty engine repair bill.

In this clients case unfortunately the timing chain had already failed and resulted in significant engine damage and only solution was to replace the entire engine.

Once the engine is removed we assessed the clients ancillary components such as turbocharger, injectors, water pump, glow plugs etc to ensure that they were not faulty as they could potentially result in another engine failure.

We prepared a refurbished engine for the client which includes many brand new internals as well as a brand timing chain kit.

The engine was then dressed with the clients components and prepped for installation.

Once the engine was installed, the vehicle went through significant testing to ensure the vehicle was running optimally before releasing it back to our client.
