Why does my Audi A4 illuminate the MECHANICAL Malfunction symbol?

Recently, the MECHANICAL Malfunction symbol appeared on my Audi A4 dashboard. What does this mean and how can I address it?

The MECHANICAL Malfunction symbol on your Audi A4 typically indicates an issue with the engine or transmission. One potential cause could be a faulty sensor or engine component. It's important to have the issue diagnosed and repaired by a certified mechanic to avoid further damage or safety hazards.

The MECHANICAL Malfunction symbol may also appear if there is an issue with the vehicle's emissions control system. This could be caused by a loose or damaged gas cap, faulty oxygen sensor, or a problem with the catalytic converter. It's recommended to have the vehicle inspected and repaired by a trusted mechanic as soon as possible to prevent any potential emissions violations.
