Moin I have two questions, maybe someone can help me. An understanding question about the start stop: My start stop has not been working for 2 weeks. In addition, undervoltage signs after the start in the morning. Exfsll several Asisstenz systems.Short engine run, restart. Everything was ok again. Car was 1 day in the workshop. Supposedly not the battery, but the battery management system, which was replaced. Start stop still does not work despite longer distances over 20 No seat heating temperature by 20° in the vehicle. Outside temperature up to 17°. Supposedly the system should not be suitable for urban traffic according to Citroën. Well. For that it is actually designed. My question. The starter battery is actually for start-up. Apart from the consumer supply in the stand. Since my system had not worked because of undervoltage, the battery should not be charged except for the start-up and be charged throughout the journey. Why does start stop still not work? Second question, which emergency call system is installed? Right ecall or air of the emergency call at a service control station on? Background:Since 1.4.2018 all vehicles with a new TYPE APPROACH have to have the “real” Ecall installed, many manufacturers simply continue to write the type approvals for their existing models. And before 4/2021 the emergency call variant with the service control stations of the manufacturer Gr If Oliver
