Fiat Novo turn signal fault
Summary of the thread
A 2020 Fiat Novo is experiencing a turn signal fault, with symptoms including an error message on the speedometer and a lighting system fault. The suspected cause is a defective cable or plug connection. After checking the bulb and considering other possibilities like a faulty relay, it was determined that the issue was indeed a defective plug connection, which was resolved at a workshop.

Yes, the bulb has been checked and replaced; the issue persists. No recent electrical work has been performed. Could a faulty relay be the cause, despite the error message pointing to a connection issue?

A relay is possible, but less likely given the stored error and the system indicating a connection fault. I've seen similar issues on other cars where it was corrosion in the connector itself. If you're not comfortable tracing the wiring, taking it to a workshop might save you time and frustration.

Thank you for the advice. Based on your assessment and my own observations, I'll proceed with a workshop visit. The repair cost was 95€. It turned out to be a defective plug connection, as suspected.

Sounds like a nuisance. Did you check the bulb itself first? Sometimes it's the simplest things. Also, have you had any other electrical work done recently that might be related?
