Hi can anyone help me, I have spent hours trying to locate this fault which I understand is a sensor that needs replacing but I am unable to fine any pictures etc that show the location for my car, any help appreciated as if possible I would like to switch out the sensor myself ?

the code above is from VCDS and is intermittent and does not show any warnings on the dash

thanks, thats really helpful. Can this be accessed easily on the drive with the car jacked up and do you know if any parts need removing to access it ?

You will need to remove the lower cover
