Hi all first post, I have an A6 allroad 2013 110000 miles on the clock , driving yesterday and got dash message parking brake system fault, fortunately it happened let than 500yards from home. Upon stopping parking brake too steep a gradient message came up. Turned engine off then restarted 10 mins later all messages gone no lights. Driven a couple miles since no messages. Any ideas? Thanks in advance
