Audi A4 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 on the Audi A4: 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.
Audi A4 Rear Springs: A Part That Fails Quietly, Then Suddenly
It's a slow decline followed by a sudden failure with the Audi A4's rear springs — a gradually lower ride height for months, then an abrupt break at the coil's end announced by a clunk. One rear corner sitting visibly lower than the other is the sign to watch for.
Audi A4 Rear Springs: OEM Part Number
| Torsion beam axle, standard rate | Confirm 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 applicable | Genuinely a stiffer rear spring rate than the equivalent standard body style, to handle the increased load-carrying capacity |
It's worth doing the Audi A4's rear springs as a pair rather than one at a time — mixing a new spring with an old, sagged one on the opposite side throws off ride height evenly and skews handling.
Audi A4 Rear Springs: What It Does
The Audi A4's 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.
