Hi, Just bought a 2006 X type 2.2diesel estate. The front and rear parking sensors do not work, despite the garage having a go at repairing them. I already own an X type sovereign in which the roof mounted switch illumitates when the parking sensors go active. However, on my estate car,this switch is completey dead. I have checked the fuses and the garage has replaced the module in the boot, but still nothing. Does anyone have any ideas?
