Some BMW diesels built between 2010 and 2017 were recalled because the EGR cooler could leak glycol that builds up in the inlet and, in rare cases, catch fire. Symptoms include coolant loss, a burning smell and white smoke.

Question 3

N47 timing chain failure (118d)

Accepted Answer

BMW's N47 2.0 diesel (2007-2014/15) is known for timing chain wear. The chain sits at the back of the engine next to the gearbox; a whirring or rattling noise from the rear of the engine is the warning sign. If the chain snaps, the engine is usually destroyed.
