C0051: steering wheel position sensor and the calibration it needs
Half of these are not faults at all — they are a sensor that was never told where straight ahead is after somebody worked on the car.

Speed limiters and driver assistance: what they do and what they do not
A limiter and cruise control are different things, and assistance systems have limits the advertising skips. The functions and their boundaries.

After a minor collision: what to check even when it is "just a scratch"
An impact that did not deploy the airbags looks harmless. But bumper sensors, the radar, and the restraints module may have suffered — and it will surface weeks later, when the link to the accident is no longer obvious.

Steering angle sensor calibration: when ESP goes crazy after wheel alignment
What steering angle sensor (SAS) is, how OBD-II sees its state, why calibration is mandatory after alignment, codes C1234, C1567, and how to do it in 5 min via scanner.
