Thread still active? I have this fault on my 13 Evoque. Battery (in freezing Temps) was 12.2V, at idle 13.9V....seems too high...? Faults been active for a week... But car starts and runs fine. . Cranks good even in sub-freezing Temps. Battery is an Interstate with 6 year warranty. .. Unsure if it's original. Also pulled the terminals off the posts and cleaned... Checked plug connectors Seems all good. Suggestions?
