Audi A5 B8 (8T) (2007–2016) (2007 – 2016)

The Audi A5 B8 (internal code 8T for Coupé/Cabriolet, 8TA for Sportback) was introduced in 2007, marking Audi's return to the compact executive coupé segment. Based on the Volkswagen Group MLB platform, it shared many components with the A4 B8. It was praised for its elegant, timeless design, high-quality interior, and refined driving dynamics. The range expanded with the A5 Cabriolet in 2009 and the A5 Sportback (a five-door coupé) in 2009. A significant facelift occurred in late 2011 (for the 2012 model year), bringing updated styling (headlights, grille, bumpers), revised interior details, and some engine improvements, notably addressing the notorious oil consumption issues on the 2.0 TFSI engines. Overall, the A5 B8 offers a premium experience, but its reliability can vary significantl

✅ Strengths

Timeless and elegant design (Coupé, Sportback, Cabriolet)
High-quality, well-appointed interior with excellent ergonomics
Comfortable ride quality, especially with standard suspension
Refined driving experience, particularly with V6 TDI and post-facelift TFSI engines
Excellent grip and stability with Quattro all-wheel drive models
Good residual values for well-maintained examples

⚠️ Weaknesses

Pre-facelift 1.8/2.0 TFSI engines suffer from excessive oil consumption
Pre-facelift S5 4.2 FSI V8 has major timing chain guide issues
Carbon buildup is a common problem across all direct injection petrol engines
Limited rear seat space in Coupé and Cabriolet models
High maintenance and repair costs, especially for S/RS models and complex engine issues
S-Tronic (DSG) transmission can be prone to mechatronic unit failures if not serviced correctly

🎯 Verdict

The Audi A5 B8 is a highly desirable car, offering a blend of style, luxury, and driving pleasure. However, a blanket recommendation is not possible due to significant reliability disparities across its engine range. Our Verdict: NÉGOCIER (Negotiate) for most models, with specific ÉVITER (Avoid) and ACHETER (Buy) recommendations for certain engines. * AVOID: Pre-facelift 1.8 TFSI and 2.0 TFSI (EA888 Gen 2) unless there is irrefutable proof (receipts, service records) that the oil consumption issue has been professionally addressed with revised pistons/rings, and the timing chain tensioner has been replaced. Also, AVOID the pre-facelift S5 4.2 FSI V8 unless the timing chain guides have been replaced, which is an extremely costly repair. * NÉGOCIER: Post-facelift 1.8 TFSI and 2.0 TFSI (EA888 Gen 3) models. While improved, they still require diligent maintenance and a budget for potential carbon cleaning or water pump issues. The 3.2 FSI V6 and RS5 4.2 FSI V8 also fall into this category; they are performance-oriented and will demand higher running costs and potential for expensive repairs. * ACHETER: The 2.0 TDI, 2.7 TDI, and 3.0 TDI V6 engines are generally the most reliable options
