Vauxhall Owners Club Posted March 10, 2023 Share Posted March 10, 2023 Seems like these errors relate to coding issues and/or CanBus communication errors. You may have to dig a lot deeper with some more serious diagnostic equipment to come up with more information. However, if the battery condition is poor and the charge level low then this could result in the Power Steering fault you describe, maybe replacing the battery if needed will resolve this issue Quote Link to comment Share on other sites More sharing options...
