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.

I had a similar problem, when it rained or when I washed the car the reversing camera did not work neither did the front sensors. The loom in the rear was replaced by the dealer and that fixed it. However sometimes it reoccurs. No help to you but at least you know that there are more owner out here with a similar problem.

Good evening James 646.

Thankyou for your reply. It is interesting to me, because I had, perhaps wrongly, discounted any connection beteen the front detectors and the rear camera system with its own detectors when reading the circuit diagrams. I will recheck the diagrams to see if I have overlooked something. So far the problem has been permanent and not intermittenet but as yet only for a short while. It is interesting to know that in your case the problem comes and goes.

Thankyou. Roger C.
