Audi A6 Rear Springs: Specs, Fitment & Common Faults

Confirmed directly in VW Group's own workshop documentation: the rear spring is a separate, distinct assembly from the shock absorber, even on the simpler torsion beam axle.

A Separate Part From the Shock Absorber — Confirmed by VW Group's Own Documentation

Genuinely worth knowing: VW Group's own workshop manuals list the rear spring as a distinct removal and installation step from the shock absorber, with its own upper and lower spring seats — even on the simpler torsion beam rear axle. This means a spring can fail (sag, crack, or corrode through) independently of the shock absorber, and vice versa, so it's worth diagnosing which has actually failed before assuming both need replacing together.

Genuinely worth knowing about axle type: the A6 uses a torsion beam rear axle on standard smaller-engined cars, and a multi-link axle on higher-output and any 4Motion/4Drive/Quattro (four-wheel-drive) variant — the spring seat design and spring rate genuinely differ between the two, so confirm your exact axle type before ordering.

A Part That Fails Quietly, Then Suddenly

A rear spring often sags gradually for months without an obvious symptom beyond a slightly lower ride height, then fails suddenly at the coil's end with an audible clunk — worth bearing in mind if you notice one rear corner sitting lower than the other.

Before you buy: rear axle type, trim, and body style all affect spring rate and fitment. Always confirm against your VIN before ordering.

Accuracy note: genuinely worth knowing: rear springs are sold in left/right pairs matched to a specific colour-coded rate marking — confirm the paint code on your existing spring rather than assuming from trim alone, since the same trim can carry different spring rates depending on options fitted.
Torsion beam axle, standard rateConfirm the colour-code marking on your existing spring before ordering — VW Group uses this to distinguish rate variants within the same axle type
Multi-link axle (higher-output/4Motion variants)A genuinely different spring and spring seat design from the torsion beam version, reflecting the different axle architecture
Estate/higher-load body style, where applicableGenuinely a stiffer rear spring rate than the equivalent standard body style, to handle the increased load-carrying capacity

Always replace rear springs in pairs — a single new spring paired with an old, sagged one on the other side creates an uneven ride height and handling bias.

What It Does

The rear coil spring supports the weight of the car's rear end and absorbs the initial impact of a bump, working alongside the shock absorber (which controls the spring's rate of compression and rebound) rather than replacing its function. A sagged or broken spring lowers ride height, can affect headlight aim, and in severe cases is an MOT failure item.
