Used Audi 100 Bonnet

The Audi 100 ran across two well-known generations in the UK: the C3 (1982–1991) and the C4 (1991–1994). Bonnets are not interchangeable between these two generations as the front-end styling differs significantly. Always quote your registration to the breaker so they can confirm the correct generation for your car.

Both years fall within the C3 generation (1982–1991), so the bonnet should be from the same platform. The C3 received a facelift during its production run, so confirm with the breaker against your registration that both cars are on the same side of that facelift boundary, as front-end panels including the bonnet can differ across it. A good breaker will cross-reference by reg to make sure the panel matches your specific car.

No — the C3 (1982–1991) and C4 (1991–1994) are entirely different generations with different body structures and front-end designs, so their bonnets do not interchange. You need to source a bonnet specifically from the matching generation. Give the breaker your registration to confirm the exact fit.

Trim level does not affect bonnet fitment on the Audi 100 — the bonnet panel itself is the same across trim grades such as C, CD, E, and S within a given generation. You may find that higher-spec cars had different badging or finishes, but the pressed steel panel is shared. Confirm your generation with the breaker and they will be able to supply the correct part regardless of trim.

Yes — within the same generation, the bonnet is a front-end panel shared across bodystyles, so the saloon and Avant estate use the same bonnet. Body length and roof height do not affect bonnet fitment. Just make sure the bonnet is from the correct generation and facelift period by confirming your registration with the breaker.

1991 sits right at the changeover between the C3 (1982–1991) and C4 (1991–1994) generations, so a 1991 car could be either generation depending on when in the year it was built. Confirm with the breaker against both registrations to establish which generation each car belongs to before assuming the panels will interchange. Once generation is confirmed as matching, fitment is far more likely, but let the breaker verify against the reg to be sure.
