I changed my power steering pump yesterday as I’ve had an intermittent power steering problem where the light would come on and the steering go stiff, usually when I’m driving. I changed the pump but the light has stayed on and the steering is still stiff, is this a matter of coding or something else as I haven’t coded the pump to my car yet as I haven’t got the software to do so. Any help would be appreciated!

There are two types of steering angle sensors, one in the steering wheel usually for cars with ESP, and another in the steering rack for cars without ESP, if you have a cable connected to the 3 connectors in the pump you have a G85 sensor , if only two you have a G250 sensor

coding should be:
X01XX for G250
X12XX for G85

it should be someting like 10111 or 11211...

you should have the pump coded for the wrong sensor, hence the light because it cant find the sensor
