Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| Air Suspension Compressor and Bellows Defective The optional air suspension on the A7 4G is prone to compressor failure and leaking air bellows. Leaking bellows cause the compressor to run continuously until it overheats. Symptoms: Vehicle sags on one side, 'Air spring: System fault' message, compressor runs continuously from 120,000 km | High | |
| Multi-Link Axle Wear TÜV reports note increasing axle and strut deficiencies with mileage. Rubber bushes and control arms wear, especially at the front axle. Symptoms: Knocking or cracking when steering and over bumps, uneven tyre wear from 120,000 km | Medium |
