What are the common electrical issues in Audi A6?

I've been having issues with my Audi A6's electrical system. The battery keeps draining and there's a constant burning smell. What could be causing this and how can I fix it?

It sounds like you could have a faulty alternator or a short circuit in your electrical system. I would recommend bringing your Audi to a trusted mechanic for a diagnostic.

One common issue in Audi A6 is a faulty battery sensor, which can cause the battery to drain quickly. You may also want to check the connections on your battery and make sure they are clean and tight.

Another possibility is a malfunctioning control module. This can cause various electrical issues such as the ones you are experiencing. I suggest taking your car to an Audi dealership for a proper diagnosis and repair.
