What's wrong?
The auxiliary heater in affected 2013-2016 Audi A5, A4 Allroad, and Q5 vehicles helps warm the cabin through the climate-control system before engine heat alone is enough. Power reaches that heater through an electrical plug connector. That connector has to hold a clean, low-resistance contact so current flows without excess heat.
On these vehicles, mechanical strain and tiny movement inside the heater connector can wear at the contact surfaces. The tin-only connector used on affected auxiliary heaters is less resistant to that wear than the later tin-and-silver design. As corrosion builds, electrical resistance rises at the connection. Higher resistance creates heat at the plug, which can overheat or melt the heater wiring.
There is no warning sign before failure. An owner should not count on a light, message, smell, or change in cabin heat to appear before the connector overheats.
