Hello, watch on my 300C 3.5, 2005er, strange charging voltage values. Otherwise, it was always at 13,7-14.1 volts. On a hot summer day or on several consecutive times it fell off a bit, then lay at 13,3-13.6 volts. Meanwhile, the Lima is new and recently also the battery. But both did not bring any improvement. Driving it is normal. If the Evic is off or you do not observe the voltage, you would think everything ok. System also has no error message. But now it hasn’t been working on for two weeks. We looked at mass contacts in the engine compartment, the battery terminals still look good. Anyone an idea?
