This is a Suzuki Ritz (Splash) 2011 DDIS Diesel car. When the car is started fresh in the morning, the idling sound is not rhythmic. It varies its slow-speed, say every other second. I have uploaded the audio of the idling sound of the engine below. The difference is ever so slightly differentiable.
Besides, the ignition is long, takes a few seconds for the engine to get started in the morning. Battery problem? (There is no service warning light turned on once the engine has started up)
- (19-July-2019) I have replaced the battery, and the long ignition problem is resolved now.
- (7-August-2019) The engine now consistently stalls by itself, if I throttle it high for a few seconds, and releases the throttle.
- (11-August-2019) A mechanic suggested, and a forum pointed out that a clogged EGR valve may cause erratic idling. Link.
