Used Audi A6 Bulkhead

The A6 has run through several distinct generations: the C4 (1994–1997), C5 (1997–2004), C6 (2004–2011), C7 (2011–2018, facelifted 2014), and C8 (2018–present), each on a different platform with a completely different bulkhead pressing. Always match your car's generation code first, as a bulkhead from the wrong generation will not fit regardless of anything else.

Both years fall within the C7 generation (2011–2018), so they share the same platform and the bulkhead should be compatible in principle. However, the C7 received a facelift in 2014, and there is a possibility of mid-generation pressing changes around that point — confirm with the breaker against your exact registration before buying to be sure.

Yes, body style is critical for a bulkhead; the Saloon and Avant (estate) have different body structures and the bulkheads are not interchangeable even within the same generation. Always tell the breaker whether your car is the Saloon or Avant when requesting a quote.

No — trim level does not affect bulkhead fitment on the A6; the SE, Sport, S Line, and Black Edition all share the same bodyshell pressing within a given generation and body style. The only differences you might notice on a used part are cosmetic items like deadening material or bracket clips that vary between cars, so mention your trim to the breaker so they can flag anything like that.

No — the C5 and C6 are completely different platforms and the bulkheads are not interchangeable. Stick to sourcing a bulkhead from the same generation as your car and confirm the exact year and body style with the breaker.

Engine and gearbox choice do not affect bulkhead fitment — the same pressing is used across petrol, diesel, and quattro variants within a generation and body style. Focus on matching generation, body style, and door count, and leave engine details out of the fitment conversation with the breaker.
