I have a 1999.5 A4-1.8T, there is a pretty loud electric motor noise behind the center console. It's not the blower motor or the radio since I turned everything off and it's still there. It's very noticeable and only when the engine is running. Has anyone else noticed the same noise? Is it normal? Anyone has any idea of what it may be before I start tearing into the console? Any information would be greatly appreciated. Thanks!
