If you own a BMW N47 diesel (118d, 120d, 320d, from ~2007-2014), this will interest you: the timing chain stretches and, if it breaks, you'll lose your engine. We'll tell you how to get ahead of it.
Why the N47 fails
The chain is located at the rear of the engine, and its design causes it to stretch with mileage. When it stretches, it can skip a tooth and bend valves – a repair costing thousands of euros.
Alarm signal no. 1: noise when cold
A metallic rattling sound when starting cold, which disappears when it warms up, is the classic sign. If you hear it, don't wait.
The professional solution
We replace the complete timing kit (reinforced chain, tensioner, and guides), with the engine timed using specialist tools. This will last you for another 200,000 km.
