Hello together, after 3.5 years my battery is probably at the end. Within 6 weeks already the second time – dead pants. Only the relays clack. Clock sets to zero and nothing goes more. Was already 6 weeks ago, there was given by the ADAC start aid and it jumped immediately again. In the Citroen workshop no error was found, battery stops the voltage ….. Now I will install a new battery. How do I get out the old ones. Are there tricks? I st yes quite installed. With best greetings bumpa
