Hello - hopefully someone can help with this. Had my 09 A4 in for a service to my local Audi garage. All done and completed. No issues. At 3000 miles, my service light came back on. Went back to Audi - they said it was an 'electric service light'. Has anyone heard of this before? My car has had enough services to last 100,000 miles and is only sitting at 30,000 miles now. Can't see how I need to pay for an electric service. Just want to make sure this is right. Any help would be appreciated. Thanks
