Video tutorial

In this video, you will see how to solve the cold start issue of the Renault Kangoo equipped with a 1.5 DCi engine. The YouTuber also performed a scan with the OBDII reader to find the reason for the difficult starting in the morning and discovered an anomaly in the preheating circuit.

The diagnosis confirms that the current is not passing through the electrical circuit, or it is passing very poorly. He demonstrates how he tested and proved this problem using a light bulb contact, which not lighting up shows that there is no current from the preheating unit.

The YouTuber evidently has knowledge of electronics as he consulted the wiring diagram, deriving precise indications, leading him to replace a faulty component: the positive power terminal of the preheater was damaged, and replacing it restored normal operation.
