As a result of trying to determine the cause of my handbrake/auto hold issues I have been looking at the battery voltage. I unnderstand that the electronic handbrake circuits are sensitive to battery voltage.
During my auto scans using VCDS, the battery voltage is reported as being 11.9-12V. VCDS battery testing shows the state of charge to be 70%.
My question is this- does VCDS report the actual voltage reading at the battery terminals, or does the voltage get regulated somewhere in the car to a nominal 12V and this is what is reported?
Car is nearly three years old with an AGM type battery, which was fully charged using a CEK 5.0 Smart charger about a month ago.
