What Does “Safe Mode” Mean on a 2001 Audi A4?

Safe mode in a 2001 Audi A4 is essentially a limp-home mode. It’s the car’s way of protecting itself from further damage when a critical system malfunction is detected.

This might mean limiting speed, disabling certain gears, or reducing engine power. You might find resources like audi a4 stereo code helpful in understanding the electronic systems within your A4.
