About the Audi A4 FSI

The B6 A4 boasts a versatile range of engines that cater to different driving needs, from the efficient 1.8T petrol to more dynamic V6 variants. With an available Quattro all-wheel-drive system on certain models, it enhances driving confidence under varying conditions.

However, like any vehicle, it requires routine maintenance to ensure longevity and performance. Key components such as the timing belt should be replaced at the specified intervals to prevent engine damage, while oil leaks, particularly from valve cover gaskets and camshaft seals, are common issues that require attention. The braking system often needs servicing, including the brake pads and rotors, which can wear out over time.
