Vibrations and pulsation when braking — what might be wrong
Steering-wheel vibration or a pulsing brake pedal have several common causes. This text explains the symptoms, possible fault sources and how professional diagnostics are carried out.
Steering hard to turn or power assist warning
Has the steering suddenly become heavy and a power assist warning or EPS message lit on the dash? Don’t ignore it — causes range from a temporary voltage drop or charging issue to a fault in the assist unit or steering sensors.
Mercedes AIRMATIC: car sags or sits unevenly
The AIRMATIC warning, sagging after parking or uneven ride height don't always indicate the same fault. We explain when you can cautiously drive to a workshop and when quick diagnostics of the air suspension are needed.
Tyre pressure warning light flashing or lit
If the tyre pressure warning light is flashing or stays on, don't assume a single cause. In many cars a steady light simply means too-low pressure in at least one tyre, but flashing for about a minute and then staying on usually indicates a fault in the TPMS or its sensors.
Tyre pressure warning light: what to do?
If the yellow tyre pressure warning light comes on, slow down and find a safe place to stop. Don’t assume a puncture straight away, but don’t ignore the warning. Check the wheels, measure pressure with a tyre gauge and inflate the tyres to the values on the vehicle placard or in the owner’s manual.
Howling while driving: tyres or wheel bearing?
If the car howls or hums louder as speed increases, you should check the tyres, wheel bearing and suspension. Tyre noise usually depends on surface and tread condition, while a worn bearing often changes tone in corners.
Steering wheel vibrations: wheels or suspension?
Steering wheel vibrations most often start with the wheels and tyres, but can also indicate play in the suspension or steering system. See how to assess the symptom before visiting a workshop.
Car pulls to one side: when to check the wheel alignment?
Car pulling to the side? Learn how to tell a wheel alignment problem from tyre pressure, brakes and play in the suspension.
Knocking in the suspension: when to act?
You can sometimes drive carefully to a service centre with a knocking suspension, but it shouldn't be left unattended. Tapping, creaking or metallic impacts can be a minor issue or play in a part that affects vehicle handling. The key is when the sound appears and whether other symptoms occur.
Tyre service and wheel alignment: when urgent
If the car pulls to one side or tyres wear unevenly, a wheel alignment check and an assessment of the tyres and suspension components is usually needed. In many cases you can still drive to get it checked, but there are situations where it’s safer not to risk driving. Below…
