Peugeot 407 Rear ABS sensor replacement

This 2006 Peugeot 407 was displaying ABS and ESP warnings on the central infotainment screen and the instrument cluster screen, as well as an ABS light on the instrument cluster.
As a result of there being an ABS fault the speedometer would not display the cars speed, the cruise control and speed limiter did not work and the sat nav also refused to work.

Plugging in a fault code reader it was determined that the rear ABS sensors were faulty.

In this video i go to the extreme of actually removing the fuel tank to change the sensors, the reason the tank is removed is that the wires for the sensors sit in tracks moulded into the top of the tank, and the connectors are located above the tank. I was giving the underside of this car a full rust protection and have videos to make so choose the longer route.

It is i believe possible to change the sensors but just lowering the tank slightly. I have a spares 407 estate which will feature in videos later on and i will try to find out then if it is possible to change the sensors without dropping the tank.
