Hi
I am sorry to say, that I dont believe that the dealer could not see or retrieve any error messages as the extent and depth of information that the car holds would really impress you - when I connected up the laptop to my XC with a rear park assis error, it claimed the error had been seen 631 times... and it showed me the code...so its all logged! Anyway - they must have seen something to give you the code they did.
Sensor two is the second from the left as you look at the rear of the car.
If the error comes and goes, I would put money on it being either a rear sensor or possibly the wiring harness from sensors to controller - there was a recall for the wiring... depending on age.
Yes - the bumper has to come off to get to the sensor - there is a big cover over all the wires and sensors that can only be removed with the bumper off.
I did a wee write up for changing a sensor - with bumper removal - have a search and you will find it... I usually append "guide" to the post so its easier to find!
