This used Audi anti-theft sensor (OEM 8W7959121, left side) comes from a donor vehicle. It monitors the cabin for unauthorized entry, triggering the alarm when tampering or motion is detected. A faulty sensor can cause false alarms or a complete failure to activate the security system. This part is compatible with EA888-based 2.0L four-cylinder engines and 3.0L V6 supercharged/turbocharged powertrains found in Audi A5 Quattro and S5 models.
