2. Roadside Repairs

This section outlines essential procedures for common issues that may arise during vehicle operation, requiring immediate attention. Familiarity with these steps can help resolve minor problems safely and efficiently.

2.1. Jump Starting

If the vehicle's battery is discharged, it can be jump-started using booster cables and another vehicle with a 12-volt battery. Ensure both vehicles are turned off before connecting cables. Connect the positive (+) terminal of the discharged battery to the positive (+) terminal of the donor battery. Then, connect the negative (-) terminal of the donor battery to a good ground point on the engine block of the vehicle with the discharged battery, away from the battery itself. Start the donor vehicle, then attempt to start the Audi A4. Once started, disconnect cables in reverse order.

2.2. Wheel Changing

In the event of a flat tire, follow these steps to safely replace it with the spare wheel. Park the vehicle on a level, firm surface and engage the parking brake. Place wheel chocks if available. Loosen the wheel nuts slightly before jacking up the vehicle. Use the vehicle's jack at the designated jacking points. Once the wheel is clear of the ground, remove the nuts completely and replace the wheel. Tighten nuts by hand, lower the vehicle, and then fully tighten the nuts in a diagonal pattern. Have the tire pressure checked and the wheel nuts torqued to specification at the earliest opportunity.

2.3. Towing

If the vehicle needs to be towed, ensure proper procedures are followed to prevent damage. For short distances and low speeds, the vehicle can be towed with all four wheels on the ground, provided the transmission is in neutral (manual) or the selector lever is in 'N' (automatic) and the steering is unlocked. For longer distances or higher speeds, or if the transmission is damaged, the vehicle should be transported on a flatbed truck or with the drive wheels lifted off the ground.

3. Weekly Checks

Regular weekly checks are crucial for maintaining your Audi A4's reliability and safety. These simple inspections can help identify potential issues before they become serious problems.

• Ниво моторног уља: Check the engine oil level using the dipstick when the engine is cold and the vehicle is on level ground. Add oil if necessary, ensuring it meets Audi specifications.
• Ниво расхладне течности: Verify the coolant level in the expansion tank. It should be between the 'MIN' and 'MAX' marks. Top up with the correct coolant mixture if low.
• Ниво кочионе течности: Inspect the brake fluid level in the reservoir. A low level could indicate worn brake pads or a leak in the system.
• Power Steering Fluid Level: Check the power steering fluid level. Low fluid can lead to difficult steering and potential pump damage.
• Стање батерије: Visually inspect the battery terminals for corrosion and ensure the battery is securely mounted.
• Tire Condition and Pressure: Check tire pressures, including the spare, against the manufacturer's recommendations. Inspect tires for wear, damage, and embedded objects.
• Washer Fluid Level: Уверите се да је резервоар за течност за прање ветробранског стакла довољно напуњен.
• Брисачи: Check wiper blades for signs of wear or damage. Replace if they leave streaks or do not clear the windshield effectively.
• Светла: Verify the operation of all exterior lights, including headlights, tail lights, brake lights, turn signals, and hazard lights.

4. Одржавање

This section details routine maintenance and servicing procedures to keep your Audi A4 in optimal condition. Adhering to the recommended service schedule is vital for vehicle longevity and performance.

4.1. Routine Maintenance and Servicing - Petrol Models

Regular servicing includes various checks and replacements based on mileage or time intervals. Key tasks include:

• Замена моторног уља и филтера: Typically recommended every 10,000 miles or annually, whichever comes first.
• Замена ваздушног филтера: Inspect and replace as needed, usually every 20,000-30,000 miles.
• Spark Plug Replacement: Replace according to the manufacturer's schedule, often every 40,000-60,000 miles.
• Fuel Filter Renewal: Replace the fuel filter at specified intervals to ensure clean fuel delivery.
• Pollen Filter Renewal: Replace the cabin air (pollen) filter to maintain air quality inside the vehicle.
• Преглед кочионог система: Check brake pads, discs, and fluid levels.
• Suspension and Steering Component Check: Inspect for wear and damage.

4.2. Halogen Headlamp Подешавање

Proper headlamp alignment is essential for safe driving and to avoid dazzling oncoming traffic. Adjustment typically involves using specific tools and following a precise procedure to set the beam pattern correctly. Refer to the detailed instructions in the manual for specific adjustment points and methods.

4.3. Auxiliary Drivebelt Removal and Refitting

The auxiliary drivebelt powers various components like the alternator, power steering pump, and air conditioning compressor. Its removal and refitting require specific steps to ensure correct tension and alignment. This process often involves releasing tension from a tensioner pulley, carefully removing the old belt, and installing the new one, ensuring it is correctly routed over all pulleys.

5. Repairs and Overhaul

This section covers more extensive repair procedures for major vehicle systems, including engine, transmission, brakes, and suspension components.

5.1. Suspension Strut Removal and Overhaul

The suspension struts are critical for vehicle handling and ride comfort. Removal and overhaul procedures involve safely compressing the coil spring, detaching the strut from the vehicle, and disassembling its components. This task requires specialized tools, such as a spring compressor, and should only be attempted by individuals with appropriate mechanical experience due to safety risks associated with compressed springs.
