I bought my 2007 S3 in June and have only recently been using the heated seats in the cold weather. I only realised there might be a problem when I noticed the passenger seat was more effective than the drivers seat on a mid range level 3 heat. I'm beginning to wonder whether i'm getting any heat at all through the drivers seat on any of the settings 1-6, it is barely noticeable. If i were to ask Audi to check it out is this covered under the 1 year used car warranty? Has anyone else experienced similar problems with heated bucket seats?
