The fault

How you spot it

On the electric power steering built from 2011 a recurring complaint is the assistance dropping out intermittently: the steering goes heavy while driving, then comes back after an ignition cycle. Over time it stops coming back, and the assistance is gone for good.

The cause is often the steering rack's own control unit or the torque sensor. If the control unit does not communicate, diagnostics often returns no fault code at all, so "no fault code, so nothing is wrong" is wrong. If the assistance drops out while driving, the steering goes heavy, and you should have it checked the same day.

How we know

Information, not an expert opinion

We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.

  • A fault on the list does not mean the car you are looking at has it.
  • A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
  • You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
