Have a 1.5dci Clio auto14 plate 63k miles. Bought July 2020. Driven everyday , mainly local to and from shops , work etc. Always bought from dealer but this was from private seller. After purchasing noticed no manual mode or reverse lights 🙄. Since March 2021 had “check auto gearbox “ message flash up. Most posts mention battery or software update. No problem starting. Because of this have In last couple of days decided to keep radio and heater fan off and message hasn’t come up. Any advice would be much appreciated.
