Audi RS3 8V Buyers Guide

Pre-Facelift vs Facelift

The RS3 8V was produced between 2015 and 2020, with a facelift introduced in 2017. The biggest mechanical change came with the switch from the CEPA/CEP engine to the DAZA engine.

• Pre-Facelift (2015-2017): Uses the older CEPA/CEP 2.5-litre five-cylinder engine. Many owners praise its sound, as it lacks a petrol particulate filter (PPF). However, it is heavier due to an iron block.
• Facelift (2017-2020): Features the DAZA engine, which has an aluminium block, making it lighter. It also has improved cooling and tuning potential. Some facelift models have a petrol particulate filter (PPF), which affects sound.

Generally, the facelift model is more desirable due to its improved performance and lower weight. However, pre-facelift models can be more affordable.

Common Issues

Before purchasing an RS3 8V, check for the following common problems:

• Haldex AWD System: Ensure the Haldex system is working properly. A clogged pump filter can reduce performance.
• DSG Gearbox: The 7-speed S-Tronic gearbox is generally reliable but can suffer from mechatronic unit failures. Look for smooth shifting and ensure no error messages are present.
• Brake Wear: The RS3 is a heavy car, and the standard brakes can wear quickly. Check for excessive wear on discs and pads.
• Suspension Components: Bushings and control arms wear over time, leading to knocking noises.
• Turbo Issues: Some owners have reported wastegate rattle and boost leaks.
• Carbon Build-Up: As a direct-injection engine, carbon deposits can build up over time, affecting performance.

Running Costs

Owning an RS3 8V comes with notable running costs:

• Tyres: High-performance tyres are essential for grip. A full set can be expensive.
• Fuel Consumption: The 2.5-litre engine is not the most fuel-efficient, especially when driven hard.
• Insurance: Being a high-performance car, insurance costs can be significant.
• Servicing: Regular servicing is crucial. The DSG gearbox requires an oil change every 38,000 miles, and Haldex fluid should be changed every 20,000 miles.

What to Look Out for When Purchasing

When buying an RS3 8V, it is essential to inspect the car carefully to avoid potential issues:

• Service History: A full-service history is crucial. Ensure all scheduled maintenance, including oil changes, gearbox servicing, and Haldex fluid changes, has been performed.
• Modifications: Many RS3s have been tuned or modified. While this can enhance performance, it may also put additional strain on components. Check for quality installations and supporting modifications.
• Accident Damage: Look for signs of previous accidents, such as inconsistent paintwork, panel gaps, or misaligned body parts.
• Test Drive: A test drive can reveal issues with the gearbox, suspension, brakes, and engine. Listen for any unusual noises and ensure the car pulls smoothly under acceleration.
• Tyre and Brake Condition: Check for uneven tyre wear, which can indicate alignment or suspension issues. Also, inspect brake discs and pads for excessive wear.
• HPI Check: A vehicle history check can reveal if the car has outstanding finance, has been stolen, or written off.

Final Thoughts

The RS3 8V is a well-rounded performance car with strong aftermarket support. If budget allows, the facelift model with the DAZA engine is the better option due to its lighter construction and improved tuning potential. However, the pre-facelift model remains a solid choice, often at a lower price point. As always, a full service history and pre-purchase inspection are recommended before buying.
