Hello together, so today my little one didn’t want to start right – it worked at the first ignition, but it took longer than usual. I immediately queried the climate code 20, but were so about the 14.0 V, after switching on d. Completed ~ 13.7 V – so actually reasonable values, or can you not rely on these values so and can not close the on-board voltage to the preliminary voltage of the battery? Only in July 2003 had a new battery installed! Greetings Ritchie (TTc 225PS quattro, Built 99)
