Audi A4 coil spring cost
A coil spring on a Audi A4 typically costs £73–£218 per side fitted at a UK independent garage, or £134–£403 as an axle pair. The A4's multi-link front end makes suspension work more involved than a strut car — and its famous wallet item is the front upper control-arm bushes, not the springs. On B9 cars, rear coil fractures at the corroded bottom coil are the documented spring pattern.
What suspension does the Audi A4 have?
The design decides the job: a spring on a strut means a strut-off, spring-compressor job, while separately-mounted springs can be quicker to swap. Here's the A4's setup:
| Axle | Design |
|---|---|
Front | Five-link multi-link front on B8 and B9 — four control arms plus track rod per side, mostly aluminium. Spring work involves the spring/damper unit plus a more complex arm cluster, with alignment afterwards. |
Rear | B8: trapezoidal-link rear axle; B9: revised five-link rear. On both, the rear spring sits separately from the damper on the lower control arm. |
Audi A4 coil spring replacement cost
One spring fitted typically costs £73–£218 at a UK independent garage, an axle pair £134–£403, and a full strut assembly (spring + shock together) £145–£436 per side. Springs are replaced in axle pairs as standard practice — uneven ride height fails the MOT.
Key things to know
- The B8's front upper control-arm bushes are the model's famous wear item — surface cracking reported from moderate mileages and audible clunking commonly at higher ones. Quotes regularly grow from 'a spring' into 'arms plus spring'.
- The front upper-arm pinch bolt on B8 cars is notorious for seizing and can add significant labour — mechanics' guides flag it specifically.
- B9 rear coil-spring fractures are documented: the powder coating chips at the bottom coil, salt gets in, and the spring breaks where it seats on the lower arm — often unnoticed until MOT.
- Adaptive damper control was a factory option on B8 and B9 — electronically valved dampers cost far more than passive ones, so check the suspension spec before quoting.
Good question
Questions Okay gets asked a lot
How much does a coil spring cost for a Audi A4?
+
Expect £73–£218 per side fitted at a UK independent garage in 2026, or £134–£403 for both sides of an axle — the usual recommendation, since uneven ride height fails the MOT and the second spring rarely lasts long after the first. If the shock absorber is worn or leaking, a full strut assembly runs £145–£436 per side. The spring itself is cheap; most of the bill is labour. Use our cost calculator to adjust for your region.
Why do Audi A4 suspension quotes grow once the car is on the ramp?
+
Because of what sits around the spring. The A4's multi-link front end uses four control arms per side, and on the B8 generation the upper-arm bushes are the model's best-known wear item — they crack and clunk at the same sort of mileages that springs and dampers tire. Once the corner is apart, worn arms are staring the mechanic in the face, and the seized upper-arm pinch bolt this model is notorious for can add real labour on its own. It's not upselling — it's the economics of shared labour. Ask for the full corner to be assessed upfront so the quote is honest from the start.
How do I know a spring has broken on a Audi A4?
+
Often a loud bang or crack over a pothole or speed bump, then a knocking or clunking from that corner, a car sitting slightly lower or lopsided, and sometimes a tyre catching on full lock. Some breaks are silent — the first sign is the MOT tester finding the snapped coil. A broken spring is a Major MOT defect, and UK potholes plus salted winter roads are the main culprits. Get it checked promptly: a snapped coil can drop and cut the tyre.
