Buying a used Audi in Germany can be a great deal for European buyers, but the engine choice is everything.
Some engines are reliable and cost-friendly, while others can become expensive very fast if you buy the wrong version or a poorly maintained car.

This guide covers the most common Audi models you can buy used in Germany from 2020 to today. You’ll find:

• Available engines (petrol, diesel, plug-in hybrid, electric)

• Power (kW and HP)

• Typical WLTP consumption and CO2 values

• Electric range for plug-in hybrid and full electric models

• Strong and weak points for each engine

• Best engine to buy used in Germany and engines to avoid
   

Note: WLTP figures vary depending on wheels, trim level, and equipment. Always check the exact values in the car’s documents. In Part I of the vehicle registration certificate (Zulassungsbescheinigung Teil I), field V.7 shows the CO₂ emissions in grams per kilometer (g/km).
 

Buying a used Audi in Germany is a popular choice across Europe because German-market cars often have strong service histories, good equipment levels, and a wide selection. But customer experiences also show that the best Audi is not simply “the newest one” or “the sportiest one.” The right choice depends on trim level, option packages, engine type, and how the car was maintained.

​

Most popular Audi trims in Europe

Across many European countries, the most searched and most purchased Audi trims tend to be S line and similar sporty styling versions. Buyers like these models because they look more premium, feel more modern, and usually have better resale value. S line models often include sportier bumpers, sport seats, larger wheels, and a more dynamic appearance, which many owners describe as the “ideal Audi look.”

​

For buyers who prioritize comfort, many reviews suggest choosing a more balanced trim instead of the sportiest styling. A standard or mid-level trim can offer a softer ride, lower running costs, and better everyday usability, especially on rough roads and in city driving. In real-world ownership, comfort can matter more than aggressive styling when you drive daily.

In the larger Audi range, body styles also strongly influence popularity. Avant (estate) models are especially popular in Germany and Northern Europe because owners value the luggage space, practicality, and family-friendly design. Sportback versions are also frequently chosen because they combine a sporty look with better usability than a traditional sedan.

​

Most wanted Audi equipment based on owner experiences

When customers describe a “good Audi spec,” they usually mean technology and comfort features that improve daily driving and make the car easier to sell later. In many Audi models, two cars can look almost identical in photos but feel completely different behind the wheel depending on the options installed.

Parking support is one of the most valued features across Europe. Parking sensors and a reversing camera are extremely popular because they reduce stress in tight parking spaces and make city driving much easier. Many buyers actively filter listings for these features, especially in larger models like the A4, A6, Q3, Q5, and Q7.

​

Digital cockpit and infotainment upgrades are another major priority. Owners often prefer Audi models with a larger infotainment screen, navigation, smartphone integration, and a more modern digital dashboard. Apple CarPlay and Android Auto are especially important for many buyers, because they reduce the need for built-in navigation and make everyday use more convenient.

​

Comfort options are also consistently rated as “worth it.” Heated seats are frequently mentioned as one of the best upgrades for winter driving in Europe. Automatic climate control, better seat materials, and upgraded interior lighting can also make the car feel significantly more premium over time.

Driver assistance features are increasingly popular, especially for highway driving. Many owners appreciate adaptive cruise control, lane assist, blind-spot monitoring, and traffic sign recognition. These systems can make long trips less tiring, but experiences can vary. Some drivers love them, while others feel certain systems intervene too strongly. That is why a test drive is important to see if the settings match your driving style.

​

Headlights are another feature that buyers care about because they directly affect safety and night driving comfort. LED headlights are considered the modern standard in newer Audi models, and many customers strongly prefer them over older halogen or basic xenon setups. Advanced lighting systems like Matrix LED can be a premium bonus on higher models, but the real-world improvement depends on the roads and driving conditions.

For engines and driving feel, quattro all-wheel drive is one of Audi’s most loved features, especially in countries with wet winters, snow, or mountain roads. Owners often describe quattro as confidence-inspiring and stable at higher speeds. At the same time, quattro models can cost more to buy and maintain, so it makes the most sense if you truly benefit from the extra traction.

​

Transmission choice also affects satisfaction. Many European owners prefer automatic gearboxes for comfort, especially in cities, while manual models can be cheaper and simpler. The right choice depends on the model, driving habits, and service history.

What customers often criticize in Audi ownership

Audi is generally praised for design, interior quality, and the premium driving feeling. But many owners also mention a few common downsides. One of the biggest complaints is ride comfort on sporty trims with large wheels. Sport suspension and low-profile tires can look great, but they often make the ride firmer and noisier on rough roads. For daily commuting, a slightly smaller wheel size is often the more comfortable and practical choice.

​

Running costs are another important topic in customer reviews. Premium cars often come with premium maintenance costs, especially as mileage increases. Owners frequently recommend choosing a car with a complete service history and avoiding models with unclear maintenance records, even if the price looks attractive.

Some drivers also mention that modern infotainment systems can feel complex at first. Audi’s menus and settings offer many options, but it can take time to get used to them. This is normal, and it becomes much easier once you understand the basic functions and shortcuts.

​

How to choose the right Audi in Germany

If you want the best Audi experience, focus on the combination of equipment, condition, and documentation rather than only the trim badge. A well-maintained Audi with practical options is usually a better long-term purchase than a sportier model with missing service records.

Before buying, check the service history carefully and confirm that important maintenance was done on time. Also review the equipment list, because some features that look “standard” in photos are actually optional in many Audi models. Finally, do a test drive to evaluate comfort, road noise, steering feel, infotainment usability, and how driver assistance systems behave.

A smart buying strategy is to choose a model that fits your real needs, then prioritize the options that improve daily comfort and future resale value. In most cases, a slightly more expensive but well-equipped Audi will deliver better satisfaction than a cheaper car that looks good but feels basic or has uncertain history.
