Twingo turn signal fault

Afternoon. My 2014 Renault Twingo (gasoline engine) is showing a turn signal fault. Error stored in the memory, message on the speedometer, and the light itself is acting up. I suspect it's a dodgy connection, but where should I start looking?

Good day. Given the symptoms you describe across multiple systems, a defective cable or plug connection is indeed plausible. Before delving into specific locations, have you observed any correlation between the fault occurrence and external factors such as weather conditions or recent maintenance activities? Furthermore, can you ascertain whether the issue is isolated to a specific turn signal lamp (left or right, front or rear) or if it manifests across all indicators?

Thanks. Seems to be the right rear. No obvious external factors that I can see, but the error seems to appear more frequently during longer trips. Any common problem areas for that specific light?

Acknowledged. The consistent occurrence during extended operation and its localization to the right rear indicator does suggest a thermal-related degradation of the connector or wiring harness. While visual inspection is always recommended, given the intermittent nature and potential for subtle corrosion, it would be prudent to consider a professional diagnostic assessment at a reputable workshop. They possess the tools to conduct load testing and insulation resistance measurements to pinpoint the precise location of the fault.

Thanks for the detailed advice! Took it to a local shop, and as you suspected, it was a corroded connector on the right rear. 95€ later and it's all sorted.
