diesel clatter got worse · diesel engine noisier than normal
The normal diesel engine clatter or knock, which all diesels have to some degree, has become noticeably louder or has changed character.
Note whether the change happened suddenly or gradually, and whether it coincided with a recent fuel fill-up - a sudden change after fueling points toward fuel quality.
Usually safe for a short trip if power and other readings are normal, but get it diagnosed soon since some causes (like worn injectors) can worsen quickly.
Describe your situation more precisely (e.g. exactly when it gets worse, how long it lasts) and get an expanded, personalized breakdown.
