Seeing a “4WD System Fault” warning or feeling rear-end jerks & noises?
That’s often caused by a worn rear differential lock selector fork – a common issue on Q5s.
💡 Instead of replacing the whole diff ( $$$ ), we rebuild the locking mechanism:
⚙️ Replace worn selector fork & bushings
🛢️ Fresh OEM-spec diff oil
🔩 Precision reassembly & coding
✅ Restores smooth AWD performance
