What Year Audi A5 to Stay Away From?

The Audi A5 model years most commonly advised to avoid are 2008–2010 (early first generation), 2013–2014 (problematic timing chains and electronics), and 2018 (first-gen B9 teething issues). These years show higher rates of expensive engine, oil-consumption, and reliability complaints compared with other A5s.

Why Certain Audi A5 Model Years Stand Out as Risky

The Audi A5 is widely praised for its design, refinement, and performance, but like many German luxury cars, some model years are more trouble-prone than others. Patterns from owner reports, recall data, technical service bulletins, and independent reliability sources reveal specific years with above-average rates of serious — and often costly — problems.

The Audi A5 Generations at a Glance

To understand which years to avoid, it helps to break the A5 down by generation and engine options, since many problems are tied to specific powertrains and early design choices rather than the entire model line.

First Generation (B8: 2008–2016, incl. facelift)

The first-generation A5 arrived in Europe around 2007 and in North America for the 2008 model year. It used a mix of 2.0 TFSI four-cylinder engines and 3.2/3.0 V6s, paired with manual, automatic, and dual-clutch (S tronic) gearboxes and either front-wheel drive or quattro all-wheel drive.

The first generation is often praised for its classic design and solid driving dynamics, but early examples developed a reputation for oil consumption, timing-chain issues, and high repair costs once out of warranty.

Second Generation (B9: 2017–present)

The second-generation A5 (B9) brought a new platform, lighter construction, more technology, and updated engines (2.0 TFSI and higher-performance S5/RS5 variants). While generally more reliable than the earliest B8 cars, the initial B9 years had “first-year” glitches, particularly with electronics and infotainment systems.

Broadly, later B9 A5s (2019 onward) have shown better reliability than the earliest B8 and early B9 cars, assuming maintenance is documented and recalls are addressed.

The Audi A5 Model Years Most Commonly Advised to Avoid

Based on patterns from owner forums, complaint databases, used-car reliability surveys, and known engineering issues, several A5 model years emerge as notably higher risk. These years tend to feature more frequent, more expensive, or harder-to-diagnose problems compared with adjacent model years.

• 2008–2010 – Early B8 launch years with widespread engine and component issues.
• 2013–2014 – Persistent timing-chain, tensioner, and oil-consumption concerns on some 2.0 TFSI cars.
• 2018 – Early B9 glitches, especially with electronics, MMI, and some drivetrain components.

These years are not universally “bad” — many owners have trouble-free cars — but statistically, they present higher odds of serious repairs and should be approached with more caution, more scrutiny, and stronger preference for warranty coverage or verified major repairs.

Early First-Gen Audi A5 (2008–2010): The Riskiest Years

The first years of a new platform often expose early design and engineering flaws, and the A5 B8 is no exception. The 2008–2010 cars sit atop most “avoid” lists for the model.

Common Problems on 2008–2010 A5 Models

These issues do not affect every car, but they appear frequently enough to matter, especially with higher-mileage, poorly maintained, or modified examples.

• Excessive Oil Consumption (2.0 TFSI) – Many early 2.0 TFSI engines are known for high oil consumption, sometimes requiring top-ups every 1,000–1,500 miles. This can be due to piston ring design, valve-stem seals, or PCV system issues, and may require expensive engine work to correct.
• Timing-Chain and Tensioner Concerns – The early 2.0 TFSI timing-chain system can suffer from tensioner failures or stretched chains, leading to rattling on start-up and, in the worst case, catastrophic engine damage if the chain skips or breaks.
• Carbon Buildup (Direct Injection) – Like many direct-injection engines of this era, the intake valves can accumulate carbon deposits, leading to rough idle, misfires, and loss of power, often requiring manual walnut-blasting cleaning.
• Early Electronics & MMI Issues – Early B8 infotainment systems and electronics can be glitchy, with failures in the MMI (navigation/infotainment), Bluetooth modules, or control units leading to costly repairs.
• Suspension and Steering Wear – As these cars age, control arms, bushings, and steering components are often worn, causing clunks or vague steering feel — repairs are not unique to Audi but can be more expensive than mainstream brands.

Because these problems can overlap — for example, a car with oil consumption and timing-chain noise — an early A5 with incomplete history can quickly turn into a high-cost ownership experience, which is why 2008–2010 examples are typically at the top of “avoid” recommendations unless they have documented major engine work and meticulous service.

Mid-B8 Years (2011–2012): Improved but Still Not Ideal

The 2011–2012 A5s benefit from incremental improvements, but some core engine-related issues had not completely disappeared, especially on the 2.0 TFSI. These years are not as widely flagged as “stay away” models, but they remain higher risk than later B8s.

What Changed — and What Didn’t

In these years, Audi implemented running updates to the 2.0 TFSI, timing components, and software, addressing some reliability complaints. However, owner reports suggest that oil consumption and carbon buildup remained common, and some cars still experienced timing-chain concerns.

• Reduced but Not Eliminated Oil Consumption – Many 2011–2012 A5s still burn more oil than expected; some received factory “oil consumption fixes” (pistons, rings, software), which should be verified in service records.
• More Stable Electronics – Compared with 2008–2010, MMI and control module failures appear less frequent, though age-related issues still occur now that these cars are over a decade old.
• Normal Aging Luxury Car Costs – As the cars approach higher mileage, expect suspension refreshes, cooling-system components, and potentially transmission service or repairs.

These cars can be decent buys if the price is right and service history is strong, but they are still not as low-risk as well-maintained later B8 or B9 A5s. They’re better than the earliest years, yet still behind the most recommended model years.

2013–2014 A5: Facelift with Lingering Engine Worries

The 2013 model year brought a facelift to the A5 — sharper styling, updated interior details, and refined features. But underneath, some of the same 2.0 TFSI timing and oil-consumption issues persisted, which is why many specialists urge caution with 2013–2014 A5s.

Why These Years Are Often Flagged

While the facelift makes these cars attractive, and many examples are reliable, enough problems exist to categorize 2013–2014 as “proceed with caution,” especially where the 2.0 TFSI engine is concerned.

• Timing-Chain Tensioner Failures – Certain production runs of the 2.0 TFSI in this era are still affected by flawed chain tensioners that can fail without much warning. Symptoms include rattling noises on cold start and timing-related fault codes. A failure can destroy the engine.
• Oil-Consumption Complaints – Although Audi implemented updates, some facelift cars still consume oil at a rate owners find excessive, with occasional cases requiring engine rebuilds or piston-ring replacement.
• Carbon & Injector Issues – Like earlier years, carbon buildup and fuel-injector faults can lead to misfires and power loss if not periodically addressed.
• DSG/S tronic Behavior – Some dual-clutch (S tronic) cars exhibit shuddering, rough shifts, or mechatronics issues, particularly if fluid changes were neglected.

Because these cars look modern and can be priced attractively on the used market, they can be tempting; however, the possibility of an engine teardown or timing-chain replacement makes them more financially risky than later B8 or well-sorted B9 cars.

Second-Generation A5 (2017–present): Which Years Raise Red Flags?

The B9 A5 introduced substantial mechanical and technological upgrades and generally improved reliability. Still, early production years — especially 2018 — are more prone to issues than later B9 models.

2017–2018 A5: Early B9 Growing Pains

First years of any new generation often involve software revisions and component updates as real-world usage reveals weak points. The 2017 and 2018 A5s follow that pattern.

• 2017 A5 – The 2017 launch year in many markets saw fewer structural issues than early B8s but did encounter some software bugs, early MMI glitches, and sporadic drivetrain complaints. Most of these have been addressed by software updates and recalls.
• 2018 A5 – This year shows up more frequently in complaint data and owner reports than 2019–2020:
  

  • MMI & Electronics Problems – Freezing screens, Bluetooth dropouts, backup camera failures, and intermittent sensor issues.
  • Driver Assist & Sensor Glitches – Lane-keep assist, adaptive cruise control, and parking sensors occasionally malfunctioning or requiring recalibration.
  • Transmission and Drivetrain Complaints – Some owners note jerky shifts, hesitation from a stop, or drivetrain warning lights.
  • Early Component Failures – Instances of water pump issues, coolant leaks, or premature battery and alternator wear reported more often than later years.

The 2018 A5 isn’t as fundamentally troubled as the earliest B8 cars, but as a used purchase, it tends to carry more risk (and more electronic complexity) than a 2019+ example with similar mileage and history.

Better Years to Consider Instead

While no used luxury car is risk-free, certain Audi A5 model years tend to be more reliable and less problem-prone, provided they were maintained properly.

Relatively Safer Audi A5 Model Years

The following years often receive more favorable reliability ratings and fewer serious complaint patterns compared with the “avoid” years, though due diligence remains essential.

• 2015–2016 (late B8.5) – Benefiting from years of incremental fixes, these final B8.5 models usually have more mature engines and fewer severe timing-chain problems. Service history is still critical, but they’re widely considered among the “sweet spot” years for the first generation.
• 2019–2021 (B9) – By this stage, many early B9 bugs were ironed out. These cars often have updated software, more robust electronics, and generally good reliability records, especially when regularly serviced at dealers or reputable independent shops.
• Certified Pre-Owned (CPO) Any Year – Regardless of model year, a factory Certified Pre-Owned A5 with extended warranty coverage and documented service history can significantly reduce financial risk.

These “better” years don’t guarantee trouble-free ownership, but they statistically provide a more favorable reliability profile and can be safer long-term bets than the early B8 and 2018 model years.

Key Problem Areas to Watch, Regardless of Model Year

Even if you avoid the riskiest A5 years, there are common problem zones to be aware of with any used Audi A5, especially as the car ages and mileage increases.

Engine and Drivetrain

Many of the A5’s most expensive issues originate in the engine and transmission. Knowing what to look for can help you spot a bad example before buying.

• Oil Consumption – Check for evidence of frequent top-ups between services. Owners should be able to tell you how much oil the car uses; vague answers are a red flag.
• Timing-Chain Noise – Listen for rattling at cold start, especially on 2.0 TFSI engines. Any timing-chain noise should prompt an inspection before purchase.
• Carbon Buildup – Rough idle, hesitation, or misfires may indicate the intake valves need cleaning. Ask if walnut-blasting has been done on higher-mileage cars.
• Transmission Behavior – On S tronic dual-clutch models, pay attention to low-speed smoothness, shift quality, and shuddering. Automatic gearboxes should shift cleanly without bangs or flares.

If a pre-purchase inspection flags significant engine or transmission concerns, walking away is often cheaper than attempting to negotiate a price that truly covers the risk of major repairs.

Electronics and Infotainment

Modern Audis rely heavily on electronics; faults in these systems can be annoying and costly.

• MMI (Infotainment) – Test navigation, audio, Bluetooth, smartphone integration, and backup camera. Reboots, freezing, or black screens suggest issues.
• Driver Assistance Systems – Confirm that adaptive cruise, lane-keep assist, parking sensors, and cameras all work. Check for any warning lights.
• Lighting and Switchgear – Test all exterior lights, interior switches, windows, locks, and climate controls.

Because electronics are intertwined, one failed module can affect several features, so a thorough system check during the test drive is critical.

Chassis, Brakes, and Body

As with any used vehicle, wear and tear on the chassis and body can reveal how the car was treated.

• Suspension Knock or Clunk – Worn control arms and bushings are common on older A5s; replacement can be pricey, especially with performance suspensions.
• Brake Wear – High-performance brakes are more expensive than typical mainstream-car components. Grooved rotors or pulsation can indicate upcoming costs.
• Rust and Paint – While Audi bodies generally resist major rust, check wheel arches, door bottoms, and underbody for corrosion, especially in harsh-climate regions.

These factors influence not only reliability but also how the car drives day-to-day, impacting your long-term satisfaction and ownership costs.

Buying Advice: How to Reduce Risk with a Used Audi A5

Even when avoiding the most problematic model years, success with a used Audi A5 depends heavily on how carefully you select and evaluate a specific car.

Steps to Take Before You Buy

Due diligence can make the difference between a rewarding ownership experience and a financial headache.

1. Check Service History Thoroughly – Look for consistent oil changes (preferably every 5,000–7,500 miles, not the longest factory intervals), timing-chain or tensioner replacements, carbon-cleaning, and transmission services.
2. Run a VIN History Report – Use services like Carfax or AutoCheck to look for accidents, title issues, odometer discrepancies, or frequent ownership changes.
3. Get a Pre-Purchase Inspection (PPI) – Have an independent Audi specialist inspect the car. Ask them to focus on engine, timing system, electronics, and suspension.
4. Confirm Recall and TSB Work – Ask a dealer to check whether all recalls and major technical service bulletins (TSBs) have been completed for that VIN.
5. Consider Warranty Options – For higher-risk years or high-mileage cars, a reputable extended warranty (or factory CPO coverage) can protect against catastrophic repairs — but read the fine print.

Taking these steps requires time and some up-front cost, but it greatly increases your odds of getting a solid A5 rather than inheriting someone else’s unresolved issues.

Summary: Which Audi A5 Years to Avoid — and Why

Across its two generations, the Audi A5 has matured into a polished, desirable coupe and sportback, but some years come with significantly higher risk. The earliest B8 models (2008–2010) are most widely recommended to avoid because of major engine issues, including excessive oil consumption and timing-chain/tensioner failures. The 2013–2014 facelift cars, while attractive, still carry notable timing-chain and oil-consumption concerns that can lead to very expensive repairs. Among the newer B9 models, the 2018 A5 stands out for elevated complaints about electronics, infotainment, and some drivetrain behavior, making later B9 years a safer bet.

For buyers, the relatively safer ground tends to be late B8.5 cars (2015–2016) and later B9 models (2019 onward), ideally with strong service history or Certified Pre-Owned coverage. Regardless of year, a pre-purchase inspection by an Audi specialist, detailed service records, and confirmation of recall and TSB work are key to avoiding costly surprises. The A5 can be a rewarding car, but the difference between a good year and a bad one — and between a well-kept example and a neglected one — can be thousands of dollars in future repair bills.
