Dear wise folk. My 2001 Octavia 4x4 is stuck in the garage having failed it's MOT. The Anti lock braking system shows a fault with the Longitudinal acceleration sensor. My mechanic can find the latitudinal and rotational acceleration sensor but cannot find the LONGITUDINAL one. This is most frustrating as one can imagine. If anyone knows where it is located that would be a great help. Many thanks, Henry:confused:
