When customers visit our VW Group specialist garage, one question that always comes up is: “Audi, Volkswagen, Skoda, SEAT – what is the actual difference?”

On the surface, these four car brands seem very different: Audi is premium, Skoda is practical, VW is the all-rounder, and SEAT has a sporty reputation. But behind the badges, they all belong to the Volkswagen Group (VAG) and share a huge amount of engineering similarities. That means similar platforms, shared engines, and familiar maintenance requirements across the range.

Let’s break down the real differences between the four from our perspective as a VAG-trained, specialist garage. We will be focusing on reliability, maintenance, servicing costs, and ownership experience.

Understanding the Volkswagen Group: Shared DNA, Different Personalities

The Volkswagen Group is built on a clever engineering strategy. They developed one set of components, used them across multiple brands, and customised each brand’s personality through design, trim, and technology. This means that an Audi A3, VW Golf, Skoda Octavia and SEAT Leon may look different, but underneath they share:

• The same MQB platform (the model’s underlying structure)
• The same TSI (petrol) and TDI (diesel) engine families
• Similar DSG (direct-shift gearbox) gearbox technology
• Shared electronics, sensors, and control modules

So if the bones are the same, what actually sets the brands apart?

An Overview of the Four Brands

Volkswagen: The All Rounder

Volkswagen (VW) is known as the in-between VAG model; balanced and for everyday use.

Its qualities include:

• A solid, confidence-inspiring build
• Comfort, refinement and a premium feel without premium pricing
• A wide model range suitable for families, commuters, business users and long-distance drivers
• Strong residual values and excellent parts availability
• User-friendly technology and ergonomics that make VW vehicles easy to live with.

The most popular VW models include the:

• Golf: The discontinued, all-rounder hatchback and VW’s best-known model
• Polo: A compact, reliable choice for city and first-time drivers
• Passat: A roomy, comfortable option for business and high-mileage users
• Tiguan: A hugely popular family SUV with strong practicality
• Transporter: Favoured for both commercial use and camper conversions.

Typical VW workshop findings:

We’d describe Volkswagen as the template for the other VAG brands. Their cars set the standard that others build from – well-engineered, predictable to service and generally straightforward to maintain.

Common Volkswagen Problems:

Although Volkswagen models are generally well-balanced and dependable, there are several recurring issues that we sometimes see in the workshop. These include:

• EGR faults on some diesel models
• Early DSG mechatronic issues on older seven-speed gearboxes
• Timing chain noise on older 1.4 and 1.8 TSI engines
• Water pump/thermostat leaks on certain TSI engines
• Coil pack failures on petrol engines.

Most of these are well-known, predictable and typically resolved with routine maintenance or timely repairs.

Volkswagen Maintenance Schedule:

Volkswagen models usually follow either Fixed or LongLife (variable) service intervals.

• Fixed Service: Every 10,000 miles or 12 months, ideal for city driving or shorter journeys
• LongLife (Variable): Up to 18,000-20,000 miles or 24 months, depending on driving style
• DSG Gearbox (wet-clutch models): Typically every 40,000 miles for an oil and filter change.

Ideal Driver Profile:

Drivers wanting reliable, well rounded, good quality cars without premium pricing.

Audi: Premium, Advanced and Complex

Audi sits at the top of the VAG family with premium materials, advanced technology and higher complexity.

Key features include:

• High-quality interiors with excellent materials
• A refined, quiet driving experience
• Strong performance options across petrol, diesel and hybrid engines
• Advanced infotainment and driver-assistance systems
• A polished, premium brand without the extremes of luxury-car running costs.

The most popular Audi models include the:

• A3: A premium, compact hatchback with strong build quality and refined engines.
• A4: A staple for business drivers, offering comfort, efficiency and a premium feel.
• A6: A larger executive option known for long-distance comfort and technology.
• Q3: A popular compact SUV combining practicality with Audi’s premium interior quality.
• Q5: A well-balanced midsize SUV, strong for families wanting comfort and refinement.

Typical Audi Workshop Findings:

From a servicing perspective, this added tech provides a high-quality experience, but also more components that can go wrong. But that’s what we’re here for!

Common Audi Problems:

Although Audi sits at the premium end of the VAG range, their more advanced technology and heavier components can lead to certain recurring issues. These typically include:

• Occasional control unit glitches (MMI, body control, gateway modules)
• Higher oil consumption on some early TFSI engines
• MagRide suspension wear on models with adaptive damping
• Display/infotainment issues such as screen freezes or reboots
• Quicker wear of brakes and suspension components on heavier or sportier models.

Audi Maintenance Schedule:

Audi uses similar servicing logic to Volkswagen, with both Fixed and Flexible schedules available.

• Fixed Service: Every 10,000 miles or 12 months, recommended for regular urban or short-trip driving
• Flexible Service: Up to 18,000 miles or 24 months, suited to long-distance drivers
• S-Tronic / DSG Gearbox: Gearbox servicing typically required every 40,000 miles.

Ideal Driver Profile:

Drivers prioritising refinement, comfort, technology, and a premium badge.

Skoda: Practical, Spacious, Value-Packed

Skoda has become a favourite among high-mileage drivers, families, and taxi/private hire owners.

Expect:

• Exceptional interior space and practicality
• Excellent value for money versus competitors
