Leaking shock absorbers can seriously affect ride, handling and stability, especially on a performance car like an AMG. This Mercedes-AMG C43 came to us with leaking rear DampTronic shocks, so we carried out a Mercedes shock absorber replacement with new units and got the suspension back to how it should feel.
The job at a glance
- Vehicle: Mercedes-AMG C43
- Problem: Leaking rear DampTronic shock absorbers
- Fix: New rear DampTronic units fitted, keeping the electronic damping

What are DampTronic shocks?
DampTronic is Mercedes-Benz’s adaptive damping system. Each shock absorber has an electronically controlled valve, and the car adjusts the damping to suit the road, the way you’re driving and the drive mode you’ve selected. It’s a big part of why an AMG can feel composed on a twisty road and still be comfortable around town.
When one of these dampers starts leaking, the fluid that controls the damping is escaping. The shock can’t control the car’s movement properly any more, and the leak only gets worse.
Signs your shock absorbers need replacing
Worn or leaking shocks often fail gradually, so it’s easy to get used to the change. If your Mercedes feels floaty, harsh, bouncy or unstable, it could be time to have them checked. Other signs include:
- The car continuing to bounce after going over a bump
- The nose diving under braking, or the car squatting under acceleration
- More body roll through corners than you’re used to
- Uneven or patchy tyre wear
- Oily residue on the body of the shock absorber
- A suspension warning message on cars with adaptive damping
Why we kept the electronic damping
When adaptive dampers fail, there are cheaper conversion options that replace them with conventional shocks. They change how the car drives, and they can leave warning lights and drive modes that no longer work as intended.
On this C43 we fitted new DampTronic units, so the electronic damping works exactly as Mercedes designed it. The result:
- New rear DampTronic shock absorbers
- Ride and handling restored
- Proper electronic damping retained
- No more leaking dampers
Do you replace shocks in pairs?
Generally, yes. Shock absorbers are replaced in pairs on the same axle so both sides of the car respond the same way. On this AMG, both rear shocks were replaced together. It’s also worth checking the front shocks, springs, mounts and bushes at the same time, so you know where the rest of the suspension stands.
Can I drive with a leaking shock absorber?
A car with a leaking shock can usually still be driven, but it won’t stop, steer or corner as well as it should, particularly in an emergency or on a wet road. Nor will it pass a roadworthy inspection. Worn shocks also speed up tyre and suspension wear. Get them checked soon rather than waiting for the next service.
