What are the precursors to BMW N20 chain failure?
1 Answers
The most common symptom is loud and noticeable noise from the N20 engine. Here are the relevant details: 1. BMW N20: It is a 4-cylinder turbocharged engine produced from 2011 to 2017. It serves as the successor to BMW's naturally aspirated 3.0-liter 6-cylinder N52 engine and is the predecessor to the current B48 engine. 2. Loud and noticeable noise from the N20 engine: This noise is relatively easy to distinguish from the noise of the high-pressure fuel pump. During mild acceleration, the engine may produce a whining sound. Chain wear can be observed by opening the oil filler cap. This issue typically occurs around 70,000 kilometers.
