The Audi A4 S4 (B7) of 2005-2009 is a prime choice for discerning drivers, seamlessly blending understated style, exceptional German engineering, and sensible running costs. The B7 generation enhanced the tried-and-true platform of its predecessor, the B6, introducing updated styling and refined engines for a more invigorating driving experience. Though it may come with its quirks, a well-maintained A4 S4 is sure to reward its owner with countless enjoyable drives, proving to be a versatile and stylish option for both city commuting and country cruising.
Common issues to watch out for on the 2.0T FSI engine include carbon buildup on the intake valves (leading to rough running and reduced performance), failing coil packs, and oil consumption issues. The Multitronic CVT gearbox (available on some models) can also be prone to failure, so check for smooth operation during a test drive. Suspension components, particularly the control arms, can wear out over time, leading to knocking noises and poor handling. Regular servicing is crucial to mitigating these issues.
Pay close attention to suspension components during WOF inspections, especially the control arms and bushes. Check for excessive play in the steering and any leaks from the power steering system. Ensure all lights are functioning correctly, including the headlights, taillights, and brake lights. The condition of the tyres is also crucial, as Audi's with Quattro drivetrains typically require correct tyre sizes and even wear across all four.
