Hello kezna welcome to Audi forum,

What problem are you facing with your A6?. A Diagnostic system?? I think you are trying to name some other part. A diagnostic system is a tool used to Scan and diagnose any problem in your car. Please do clarify what exactly needs to be replaced from your service ppl.
