Audi A6 C5 (1997-2004): How to Remove Bumpers

When Audi introduced the A6 with C5 body style in 1997, it wasn't just another executive sedan but a true technological breakthrough. The model replaced the previous generation Audi 100 (C4) and immediately established itself as a more modern, stylish and innovative vehicle.

Generation and Internal Designation

The Audi A6 C5 represents the fifth generation of the series, factory designated as Typ 4B. Interestingly, the station wagon (Avant) version used a separate code: 4B5.

Production Years and Facelift

The C5 generation was produced from 1997 to 2004, receiving a minor update in 1999 and a significant facelift in 2001 that affected both appearance and technical components.

Pre-facelift, the A6 C5 featured rounded headlights and soft lines characteristic of late 90s design. After 2001, the car received new lighting, a more aggressive grille, redesigned bumpers and more modern engines.

Modifications

The Audi A6 C5 was available in several body styles:

  • Sedan - the classic executive version

  • Station wagon (Avant) - more practical but equally stylish

  • Allroad - unique version with increased ground clearance, permanent all-wheel drive and air suspension for light off-road use

The engine selection was extensive:

  • Petrol: from modest 1.8L (125 hp) to powerful 4.2 V8 (300 hp)

  • Diesel: particularly popular were the 1.9 TDI (110-130 hp) and 2.5 TDI (150-180 hp) turbodiesels, known for reliability and efficiency

  • Transmission: 5- and 6-speed manuals, plus 5-speed Tiptronic automatic
