My model. XF-S 2010.5 MY 3.0lt. Diesel. Premium luxury. Front parking detectors, rear parking detectors and rear camera.
Recently the front detectors have failed to indicate when I move towards a fixed object or notice if someone passes the front when the system is operative. The rear system and camera are all ok. I've looked at the circuit diagrams and notice that the parts common to the front sensors are the connectors, (a) under the front bumper and (b) the feed and return connector to the control unit in the boot. However I've just used my iCarsoft device and no faults show up. The volume was set to high to check them this morning and individually they sound when very close in, by me moving by the front. Water ingress is mentioned in the possible faults list on the internet. I'm wondering whether other members have had a similar problem and know which is the more likely fault, (a) or (b) or some thing completely different. Sadly I'm no longer able to tackle the "bumper off" to look for connectors and could eventually be at the mercy of a garage but would like more information beforehand if available.
