Rain sensor calibration

Rain sensor calibration – for precise and reliable visibility on the road

The rain sensor is one of those subtle but very important technologies that make everyday driving more comfortable and safer. It automatically activates the windscreen wipers, adjusting their speed according to the intensity of the rain, helping the driver to maintain constant visibility in all weather conditions. But this technology only works effectively if the rain sensor is properly calibrated.

Rain sensor calibration is the process of ensuring that the sensor responds accurately to moisture on the windscreen. This is particularly important after windscreen replacement as the sensor is removed and reinstalled, often with a new mounting bracket and optical alignment surface. Even small deviations can cause the sensor to operate inaccurately – for example, windscreen wipers start working too late or too fast.

Calibration ensures that the sensor “sees” moisture as accurately as the vehicle manufacturer intended. It also means that the system will operate smoothly, without interference or excessive sensitivity that could annoy the driver.

Our service uses only Hella original diagnostic equipment and software to carry out a professional rain sensor calibration. We ensure that each sensor is precisely tailored to the specific windscreen and vehicle control system.

Have you recently changed your windscreen or notice that the wipers are not working as usual? Your car may need a rain sensor calibration. Leave it to the professionals – we’ll make sure your visibility is always clear.
