Older Mercedes-Benz models use hydraulic power steering with a pump, hoses and fluid, while most newer models use electric power steering built into the steering rack, controlled by its own module. Some models also have Direct-Steer variable ratio steering, and the latest S-Class, E-Class and EQ models can have rear-axle steering. On some models from around 2007 to 2014, a failing electronic steering lock can stop the car from starting. At Orange Auto in Al Quoz and Nad Al Hamar we test the steering system properly, with diagnostics and a hands-on check of the rack, joints and linkages, before recommending any repair.
We feel for heaviness, play, knocks, vibration and whether the steering returns to centre properly.
We read faults from the steering module and check the steering angle and torque sensor values.
On the lift we check tie rod ends, inner joints, rack boots, mounts and, on hydraulic systems, the pump, hoses and fluid.
We explain what is worn and the options, from joints and seals to a repaired or replacement rack.
Parts are replaced with genuine or quality OEM components, and hydraulic systems are refilled with the correct Mercedes-approved fluid.
After rack or sensor work we calibrate the steering angle sensor and run any setup the electric steering needs.
We align the wheels and road test to confirm the steering is straight, smooth and fault free.
Any steering work that touches the tie rods needs a wheel alignment afterwards. See Mercedes wheel alignment.
A whining noise on full lock or damp hoses usually means low fluid. Fixing the leak early protects the pump and rack.
Sudden heavy steering with a warning light can come from low voltage, a sensor or the rack motor. A battery check is part of our diagnosis.
If the key will not turn or the car will not start and the steering stays locked, the electronic steering lock may be at fault. We test it before replacing anything.
Knocks can come from steering joints or from suspension parts. See Mercedes brakes and suspension repair.
Is it safe to drive with a steering warning?The steering may become heavy without warning. Drive carefully and have it checked as soon as possible.
Can a steering rack be repaired?Sometimes. We compare repair and replacement costs for your car.
Why does my steering wheel shake?Often wheel balance or brake discs, sometimes worn steering joints. We find which one.
