After several tests at Renault, it is concluded that the battery charger will have to be replaced.
I have already moved forward with repair and replacement. As soon as I have more news I inform everyone.
In the meantime, I also discovered that the car’s chassis has several rust spots. It is still under the corrosion warranty and I asked for the inspection to appeal the warranty. Let’s see what happens.
I bought the used car on a Portuguese island (Azores) and definitely the cars are not prepared to be in a site with so much aggressive exposure.
Alert to users here on the forum, who live near the sea or in snow environments, who are aware of the appearance of corrosion.
This might have been a subject for an independent topic.
As soon as you have news, report.
Greetings to all.
