【Review】2024 Audi A4 Review: A Used Car Buyer’s Guide (2025)

The 2024 Audi A4 represents an excellent used luxury sedan value in 2025, offering mature B9 generation reliability with standard driver assistance features at prices averaging $29,000-35,000. This second-to-last year model combines proven mechanical systems with enhanced technology, making it particularly attractive for buyers seeking German luxury without new car depreciation.

2024 Audi A4 B9 Generation Overview

The 2024 model year marked the penultimate chapter of the B9 generation, which debuted in 2017 and established itself as one of Audi’s most reliable platforms. After seven years of refinement, the 2024 A4 arrived as what industry insiders call a “mature product”—all the significant bugs worked out, yet still modern enough to compete with newer rivals.

2024 Audi A4 Carryover Model Status

As a carryover model, the 2024 A4 maintained the successful formula established in previous years while adding strategic updates to enhance value. This approach is common when manufacturers near the end of a generation, allowing them to focus resources on upcoming redesigns while keeping current models competitive.

What’s New for 2024 Audi A4

The most significant change for 2024 involved making previously optional driver assistance features standard equipment across all trim levels. Adaptive cruise control, lane-keeping assist, and parking assist became standard, adding approximately $2,100 worth of technology at no extra cost^[1]. This move addressed a common criticism that Audi charged extra for features competitors included standard.

The MMI infotainment system received software updates improving response times and adding wireless Apple CarPlay functionality to complement the existing wired Android Auto. Navigation became standard on Premium Plus trim, previously a $1,800 option. These changes made the 2024 model particularly compelling in the used market, as buyers get more features without paying the premium early adopters faced.

2024 A4 vs 2025 A4 Comparison

Understanding the differences between 2024 and 2025 models helps used buyers make informed decisions. The 2025 model year brought more dramatic changes, dropping the entry-level 40 TFSI engine entirely and adding remote start as standard equipment.

Feature	2024 A4	2025 A4	Impact for Used Buyers
Engine Options	40 & 45 TFSI	45 TFSI Only	More 2024 choices available
FWD Availability	Yes (40 TFSI)	No	Last chance for FWD option
Remote Start	Not Available	Standard	Minor convenience difference
Base MSRP	$41,900	$43,295	Better value proposition
Driver Assists	Newly Standard	Standard	Same safety features

The retention of both engine options in 2024 provides used buyers more flexibility, particularly those seeking the more affordable 40 TFSI with front-wheel drive—an option that disappeared for 2025.

Is the 2024 Audi A4 a Good Car

According to multiple automotive authorities, the 2024 A4 earned strong ratings across key evaluation criteria. Consumer Reports awarded it a predicted reliability score of 4 out of 5^[2], placing it above average for luxury vehicles and ahead of direct competitors like the BMW 3 Series.

2024 Audi A4 Review Used Market Analysis

Current used market data shows 2024 A4 models selling between $26,998 and $35,000 depending on trim level and mileage^[3]. With original MSRPs ranging from $41,900 to $52,000, this represents depreciation of 25-35% in just one year—typical for luxury sedans but advantageous for used buyers.

Autvex analysis of nationwide inventory reveals Premium Plus models with the 45 TFSI engine offer the best value, typically priced around $31,000 with under 30,000 miles. These vehicles retain most of their factory warranty, providing peace of mind absent in older used luxury cars.

2024 Audi A4 S Line Features

The S Line appearance package, popular among 2024 buyers, adds sport-focused styling without the S4’s performance premium. Features include unique 18-inch wheels, sport suspension lowering ride height by 0.9 inches, aggressive front and rear bumpers, and aluminum interior trim. Used examples with S Line typically command a $1,500-2,000 premium but offer enhanced visual appeal and slightly sharper handling.

The S Line’s sport seats provide better lateral support than standard seats, important for enthusiastic drivers. However, the lowered suspension creates a firmer ride that some find uncomfortable on rough roads—a consideration for used buyers prioritizing comfort.

2024 Audi A4 Drivetrain & Performance Options

The 2024 A4 offered two distinct powertrain configurations, each targeting different buyer priorities and representing the last year for this flexibility.

2024 Audi A4 40 TFSI FWD (Last Front-Wheel Drive)

The 40 TFSI marked the final year Audi offered front-wheel drive in the A4, making 2024 models unique in the used market. This configuration appeals to buyers in warmer climates who don’t need all-wheel drive’s added complexity and cost.

2024 Audi A4 40 TFSI Quattro (Optional AWD)

For those wanting all-weather capability without stepping up to the more powerful engine, the 40 TFSI with optional quattro all-wheel drive provided an ideal middle ground. The $2,100 quattro option added only 150 pounds while improving traction significantly. Used examples with this configuration typically show minimal price difference from FWD models, making them excellent value.

The ultra-technology quattro system disconnects the rear axle during steady cruising to save fuel, engaging within milliseconds when slip is detected. This intelligent operation means AWD models achieve nearly identical fuel economy to FWD versions—a significant improvement over previous generations.

2.0L Turbocharged 4-Cylinder Specifications

Both engines share the EA888 Gen 3B architecture, among the most refined turbocharged four-cylinders in production. The 40 TFSI produces 201 horsepower and 236 lb-ft of torque, adequate for daily driving and highway merging. Direct injection and variable valve timing optimize efficiency, while the turbocharger provides immediate response from just 1,450 rpm.

The 12-volt mild hybrid system adds a belt-driven starter-generator that enables seamless stop-start functionality and recuperates energy during deceleration. This technology improves fuel economy by approximately 0.7 mpg in real-world driving while eliminating the jarring restarts common in earlier stop-start systems.

2024 Audi A4 45 TFSI Quattro (Standard 261 hp)

The 45 TFSI represents the enthusiast’s choice, delivering substantially more performance for a modest price premium. Standard quattro all-wheel drive ensures the additional power translates to confident acceleration in all conditions.

2024 Audi A4 40 vs 45 TFSI Horsepower (201 hp vs 261 hp)

The 60-horsepower difference between variants transforms the driving experience. While the 40 TFSI feels adequate, the 45 TFSI provides genuine thrust that makes highway passing effortless. The additional power comes from increased boost pressure and optimized engine mapping rather than mechanical differences, ensuring similar reliability between variants.

Torque tells an equally important story: 236 lb-ft versus 273 lb-ft. This 37 lb-ft advantage manifests in stronger mid-range acceleration, particularly useful when climbing grades or carrying passengers. The seven-speed S tronic dual-clutch transmission handles the extra torque without issue, having been proven in higher-output S4 applications.

2024 A4 0-60 Time (45 TFSI: ~5.1s)

Independent testing confirms Audi’s claimed 5.1-second 0-60 mph time for the 45 TFSI, impressive for a luxury sedan prioritizing refinement over outright performance^[4]. The 40 TFSI requires approximately 7.1 seconds for the same sprint—still respectable but noticeably less urgent.

Real-world acceleration feels stronger than numbers suggest thanks to the immediate torque delivery. Unlike naturally aspirated competitors that require high revs for power, the turbocharged A4 pulls strongly from any speed. This characteristic proves particularly valuable in daily driving where full-throttle acceleration is rare.

2024 A4 MPG and Fuel Economy

Fuel efficiency remains a strong suit despite performance capabilities. The EPA rated the 40 TFSI at 27 mpg city, 36 highway, and 30 combined for front-wheel drive models. Adding quattro reduces these figures by just 1 mpg across the board—remarkable given the added mechanical complexity.

The 45 TFSI achieves 24 city, 32 highway, and 27 combined with standard all-wheel drive. Real-world testing by Autvex confirmed these figures are achievable with normal driving, though enthusiastic use of the available performance naturally reduces economy. The 15.3-gallon fuel tank provides over 450 miles of highway range, reducing fuel stops on long journeys.

2024 Audi A4 Common Problems

While generally reliable, certain issues deserve attention when evaluating used examples.

Historical 2.0L TFSI Engine Issues

The EA888 engine family has known vulnerabilities that persist across generations, though severity has decreased significantly:

1. Oil consumption: Earlier versions consumed up to 1 quart per 1,000 miles. The 2024’s Gen 3B engine reduced this to acceptable levels, though some consumption remains normal
2. Carbon buildup: Direct injection engines accumulate carbon on intake valves over time. Professional cleaning every 40,000-50,000 miles prevents performance degradation
3. Water pump/thermostat: The plastic housing can fail around 60,000 miles, though updated parts last longer. Replacement costs approximately $800-1,200^[5]
4. Timing chain tensioner: Early failures prompted updates. Post-2020 models use improved tensioners with no reported issues

These concerns shouldn’t discourage purchase but inform maintenance planning. Following Audi’s service schedule and using quality oil prevents most problems.

2024 Audi A4 Recalls

Several recalls affect 2024 A4 models, though most involve free repairs at dealers:

• Sunroof detachment (certain VINs): Improperly bonded glass requires inspection and potential reinstallation
• Instrument panel software: A software glitch can cause the display to black out while driving. Free software update resolves the issue^[6]
• Fuel pump module: Some early 2024 builds received faulty fuel pump modules that could fail without warning

Checking recall status through Audi’s website or NHTSA database ensures all campaigns are complete before purchase.

The G70’s 2.0-liter turbo matches the A4 45 TFSI’s output while its 3.3-liter twin-turbo V6 option provides M3-challenging performance.

Where Genesis falls short is brand prestige and dealer network. With only 65 U.S. dealerships versus Audi’s 350+, service convenience becomes a consideration. The A4’s superior resale value typically offsets initial savings, making total ownership costs similar.

Used Car Buyer’s Checklist for 2024 A4 (2025)

Proper evaluation ensures you select a well-maintained example avoiding costly surprises.

Verify Service Records and Maintenance History

Complete service documentation is non-negotiable when buying a used luxury car. Look for evidence of oil changes every 5,000 miles using approved 0W-20 synthetic oil. The S tronic transmission requires fluid service every 40,000 miles—missing this causes premature wear.

Check for completion of the 20,000-mile major service including cabin air filter, engine air filter, and brake fluid replacement. Dealers charge approximately $400-600 for this service, so negotiation leverage exists if it’s overdue. Verify recall campaigns are complete through Audi’s website using the VIN.

Get a Pre-Purchase Inspection (PPI)

Professional inspection by an Audi-familiar technician costs $150-300 but can identify thousands in potential repairs. Key areas requiring attention include:

• Scanning for stored fault codes in numerous control modules
• Checking for oil leaks around the valve cover and oil pan
• Inspecting water pump for seepage (common failure point)
• Evaluating brake pad and rotor thickness
• Testing all electronic features including driver assists
• Examining suspension components for wear

Request the inspection report in writing with repair estimates. Use findings to negotiate price adjustments or walk away from problematic examples.

Check for Warranty Coverage

Most 2024 A4s retain factory warranty through 2028 (4 years/50,000 miles from original sale date). Verify coverage status through Audi directly, as warranties transfer between private parties. Extended warranty options through Audi or third parties cost $2,000-4,000 depending on coverage level and duration.

Consider Certified Pre-Owned examples offering warranty extension to 2029 with unlimited mileage. While costing more initially, CPO designation includes thorough reconditioning and inspection providing additional peace of mind.

Decision Path / Next Steps

Start your search focusing on Premium Plus models with the 45 TFSI engine, offering the best balance of features, performance, and value. Set a budget of $31,000-33,000 for well-equipped examples with under 30,000 miles. Expand to Premium trim if budget-conscious, but expect to sacrifice desirable features like Virtual Cockpit.

Use Carfax or AutoCheck reports to eliminate vehicles with accident history or unclear maintenance records. Focus on single-owner cars with complete service documentation from Audi dealers. Private party sales offer better prices but require more diligence, while dealers provide convenience and potential certification.

Schedule pre-purchase inspections for your top 2-3 candidates, comparing findings to identify the best-maintained example. Don’t skip this step to save $200—identifying one significant issue pays for the inspection many times over.

Negotiate based on market comparisons, necessary maintenance, and inspection findings. The abundance of 2024 models entering the used market creates buyer leverage. Target 5-8% below asking price for dealer sales, potentially more for private party transactions.

Consider financing through Audi Financial Services, which often offers competitive rates for CPO vehicles. Credit union rates typically beat dealer financing for non-certified cars. Factor insurance costs into your budget—luxury vehicles cost more to insure, though the A4’s strong safety ratings help moderate premiums.

Plan for ownership costs including premium fuel ($300-400 annually extra versus regular), synthetic oil changes ($80-120 each), and potential repairs once warranty expires. Budget $1,500-2,000 annually for maintenance and repairs after warranty, though well-maintained examples may require less.
