Audi Q3's second maintenance includes the following items: 1. Replace engine oil, oil filter, air filter, and cabin air filter; 2. Clean throttle body and fuel injectors; 3. Four-wheel brake maintenance; 4. Inspect front and rear brake pads and tires. The second maintenance refers to the secondary maintenance, which is a maintenance operation centered on inspection and adjustment for motor vehicles that have traveled a certain mileage. The body dimensions of the Audi Q3 are: length 4495mm, width 1848mm, height 1616mm. It is equipped with a 1.4L turbocharged engine, with a maximum power of 110kW and a maximum torque of 250Nm, paired with a 7-speed dual-clutch transmission.

Just completed the second maintenance for my Audi Q3, which is essentially a 'teenage health checkup' for the vehicle. The official manual mandates an oil and oil filter change as a must-do, with about 5 liters of 5W-30 full synthetic oil required. The air filter can simply be removed and blown clean unless you frequently drive on construction sites. Tire rotation is essential, as Audi's quattro system tends to cause uneven wear—I noticed the left rear tire was wearing unevenly last time. Brake fluid inspection is crucial; the mechanic can quickly determine if the moisture content exceeds standards with a tester. Don’t forget the cabin air filter! Last time I skipped it, and there was a dusty smell when using the AC in summer. The mechanic also runs a diagnostic scan for error codes, which is vital for cars with complex electronic systems. The cost is around 1,200 for basic maintenance, plus over 300 for brake fluid inspection, and you can save 200 by replacing the cabin air filter yourself.

The second maintenance should focus on the core items: Engine oil and oil filter are the lifeline, must be replaced with genuine 5W-30 specification, and the drain plug washer should be replaced as well. Pay close attention to the tightening of chassis bolts - my friend's car once had abnormal noises due to loose screws. Let the technician inspect the filters before deciding; cleaning the air filter and replacing the cabin air filter promotes better health. Tires must be cross-rotated, as Audis wear unevenly 30% faster than regular cars. Final inspection items cannot be skipped: brake pads with less than 5mm thickness should be scheduled for replacement, coolant freezing point tested with a refractometer is extremely accurate (I've personally seen aged fluid change from -25°C to -15°C on the device). Perform system upgrades if available, as infotainment lag is often a software issue. Engine oil and filter change with labor costs approximately 1100 yuan.

The key points for my Q3's second maintenance are as follows: Engine oil and oil filter must be replaced, and the shop uses a specialized pump for thorough extraction. The air filter depends on the condition; it's recommended to replace it in northern areas with heavy sand and dust. The critical part is the chassis inspection! The mechanic checks it meticulously with a lift: Early detection of cracks in the steering ball joint rubber boot is essential, and axle seal oil leakage is a common issue. I strongly recommend wheel balancing for the tires; last time, not doing it caused steering wheel vibration at 110 km/h. The battery test shows 78% lifespan; prepare to replace it when it drops below 60%. Finally, have the technician reset the maintenance reminder, which takes just 5 seconds by entering the engineering mode on the operation screen. The cost for the basic package is 1150 yuan, including free inspection labor fees.

The second maintenance items depend on the season. In spring, the focus is on the air conditioning system: replace the activated carbon cabin air filter to prevent allergies, and flush the condenser to avoid clogging from willow catkins. For routine items, engine oil must meet VW502 certification due to the high precision of Audi engines. During tire rotation, insist on checking the tire pressure sensors—my rear right sensor gave a false alarm last time. Wiper blades are recommended for replacement, as OEM rubber blades start streaking after about a year and a half. Additionally, request an inspection of the sunroof guide rails—Q3's sunroof drainage holes are prone to clogging, which can cause water seepage in the A-pillar. The basic maintenance plus AC system service totals 1,400 RMB, and remember to bring your first maintenance receipt for a 10% discount.
