In many popular Renault inline-four engines (such as the 1.4L, 1.6L K4M, or 2.0L F4R units found in the Clio, Megane, Laguna, and Logan), the ignition system operates on a "wasted spark" or paired-coil configuration. This means cylinders 1 and 4 are driven simultaneously by the same electrical circuit from the ECU. If the ECU detects that the electronic "driver" transistor cannot successfully turn the coil on or off, it generates DF361 to isolate the problem to that specific pair.
Diagnosing DF361 requires a systematic approach to pinpoint the failure between the spark plug, coil, or wiring. 1. Initial Scanning renault df361
The effect of this error on your car's performance varies depending on the specific engine and the severity of the problem. However, here are some of the most typical signs reported by drivers: In many popular Renault inline-four engines (such as the 1
: The most frequent culprit is a physically degraded or internally shorted coil pack. Diagnosing DF361 requires a systematic approach to pinpoint
A failing injection relay or a blown circuit fuse (such as the main injection ECU supply fuse) will cut power to the ignition system entirely.
