Change the six candles of a 2005 Smart Cabrio Roadster coupe.

Model: Smart Smart Roadster, 452 - Years 2003-2005
Part: Spark plugs

In this somewhat controversial video, the YouTuber - a respected professional - takes issue with amateur mechanics who, either due to lack of knowledge or unwillingness to do a complete job on a car that presents management difficulties like the 2005 Smart Cabrio Roadster coupé in the video, perform incomplete work that damages the vehicle. In fact, this car has the difficulty of having six spark plugs, three of which are easily accessible, while the others are difficult to reach even by removing several parts of the car: in fact, angular tools are still needed. Those who did the work previously simply ignored the problem by not changing the three poorly accessible spark plugs, causing damage to the engine. The YouTuber's invitation is therefore to - if you rely on a professional - be sure of their reliability and competence, and to verify the work done.

Under this panel, you will find the fuses, including the one for the central locking, which is indicated in the manual as number 14. To reset the system, remove this fuse from its housing, then reinsert it or replace it with a new one of the same amperage: this will reset the central locking system.
