My battery is perfectly ok, but I would like to temporarily remove it, and put it back a few hours later. Does anyone know what the consequence would be in terms of error messages, fault codes, etc. On my last car (VWPassat) this would throw up various error messages, but a short drive would clear them. Is it the same with the A3? I don’t have VCDS, and I want to avoid a trip to the dealer to have fault codes reset.
