What are the essential maintenance items for an Audi A6 major service?

Audi A6 major service, in addition to replacing wear-and-tear parts, may also include replacements for components like tires and batteries. The comprehensive maintenance involves inspection and servicing of dozens of items across multiple systems including the engine, transmission, air conditioning system, steering system, braking system, suspension, body, and tires. Below is a relevant introduction to car maintenance: 1. Exterior inspection: Before driving, check the doors, hood, trunk, and glass condition. Inspect for body damage, tilting, oil leaks, or water leakage. 2. Engine and various fluids: Check the fastening condition of engine components and inspect for oil or coolant leaks at engine joints. Adjust belt tension and inspect the securing status of pipelines and wiring. Top up engine oil, coolant, and electrolyte as needed. 3. Tires: Examine tire wear patterns and clean the trunk. Replace tires when tread wear indicators become visible. Check for bulges, abnormal wear, aging cracks, or physical damage. 4. Cleaning and lubrication: Remove grease from hood hinges, door hinges, and trunk mechanisms, then lubricate them. Antifreeze typically has a 2-year service life and should be replaced during maintenance with thorough cooling system flushing. Due to brake fluid's hygroscopic properties, replace it every two years.
I've been running a repair shop for ten years. For an Audi A6 major service, these six items are a must: Engine oil and oil filter are the basics, and you must use full synthetic oil; Transmission fluid must be changed at 80,000 kilometers, or gear wear could cost tens of thousands to repair; Brake fluid should be replaced every two years, as it absorbs moisture and can cause soft brakes; Spark plugs need replacement at 40,000 kilometers—older Audis often have ignition issues; Both the air filter and cabin air filter should be replaced, or the engine will struggle and consume more fuel; Finally, check the brake pads and tires, and retighten the chassis bolts. Don’t forget to have the mechanic scan for fault codes—Audi’s electronic systems are complex, and small issues can escalate into major problems. After completing these services, the car should easily run another 100,000 kilometers without trouble.
As an Audi A6 owner for five years, I focus on five key items during major maintenance: Transmission fluid replacement is particularly crucial, as OEM fluid protects the gears; Spark plugs must be changed - Volkswagen group engines tend to vibrate without them; All cabin filters need renewal, especially the AC filter which affects interior air quality; Brake fluid requires complete replacement, more frequently in humid southern regions; Belt and tensioner inspection is vital as breakage can cause immediate breakdown. My last full set cost over 3,000 RMB, but afterwards fuel consumption dropped by more than 1L/100km and gear shifts became noticeably smoother - definitely a worthwhile investment.
