What is the reason for the rattling sound when the Audi A6L starts at low speed?

It is mainly caused by excessive wear of some parts or improper assembly and adjustment. The following is a related introduction to the Audi A6L: 1. Introduction: The Audi A6L is the first Audi model to enter the Chinese market, with its predecessor being the third-generation Audi 100 (code C3) introduced in 1988. The Audi A6L is a vehicle series developed by FAW-Volkswagen Audi based on the German new A6 and is the successor to the A6. In June 2012, the new-generation Audi A6L was launched, equipped with 35-TFSI power, and its appearance somewhat resembles the new version of the A4L. 2. Design: The new Audi A6L adopts a five-link front suspension design, balancing the necessary rigid connection for sportiness and comfort with low static stiffness. Among them, the hydraulic form of the frame shock absorber support can significantly improve the driving comfort of the vehicle and effectively reduce the impact and jerkiness when passing over speed bumps and uneven roads, thereby reducing the impact on the lumbar spine.
I've driven many Audi cars before, including the A6L. A rattling sound during low-speed starts is most commonly caused by issues in the suspension system, such as aging or loosened ball joints in the shock absorbers or control arms, which lead to vibrations. Sometimes it could also be due to wear in the universal joint of the driveshaft, which produces noise during driving. I've encountered similar situations before, and it was only after a check at the repair shop that I found out the suspension linkage needed replacement. Additionally, loose components in the brake system, such as caliper screws, can also cause rattling. Audi cars are precision-engineered, but these minor issues are normal after long-term use. I recommend having technicians inspect the chassis more thoroughly during regular maintenance—don't delay too long, as problems could become more dangerous at high speeds. Remember, unusual noises aren't just minor issues; addressing them early saves both hassle and money.
