My wife had her auto gearbox swapped by a local garage, I took it for a spin when she got home but noticed the steering wheel out of line with the ESP warning lit on dash. She took it back to garage for them to rectify, although they claimed they did not touch it, but they said that they could not set it (?) to zero!

Initially I didn't scan the car but the ESP light is back on again and curiosity has got the better of me,

Can someone shed some light on what is causing the sensor to fail please, H
here is the scan.............
