Before you replace any wiring I would first replace both the front and the rear brake pad sensors with OEM sensors if you have not already done so. The front brake pad sensor wire connects at connector F pin 14 at the front signal acquisition module. It should be a white wire. The module is located in the battery compartment below the front seat. I've attached a picture below.

it was in with MB for a whole day and they told me it was the front sensor, so I have taken the whole of the front of the car apart. With your information I was able to determine it was not the front sensor.


So I started looking at the back sensor (blue wire) to find that it was a straight forward faulty earth from the rear sensor. Remade an earth and problem gone.
