These cars had a problem with the drivers seat wiring harness rubbing against the seat frame. If you can get the fuse to blow while moving the back and forth and bouncing around in it this may be your problem.you would have to remove the driver side seat to fix the wire.this problem causes the driver doors to appear open in the information window on the cluster. Check this out first. I was a auto tech at an Audi dealership for 6 years. If you take this car somewhere else to get fixed it could coast you an arm and a leg just in diagnostic fees if they don't know what to look for. Hope this helps.
I Have A 1999 Audi A6, Fuse #14 Keeps Blowing. The Instrument Cluster Shows That All The Doors Are Open (when In Fact They Are Not). I Can Not Open The Windows Or The Sunroof; The Interior Lights Do Not Work. There Might Be Other Electrical Problems As Well, But I Have Not Tried Everything.Any Idea What Could Be Wrong?
Did you ever solve this problem? I have the same issue with my 2001 A6. It is not the driver door that is shown to be open, it is all the other doors.
