About 6 months ago I started getting the dreaded 5 second beep and warning light on the overhead console when I put my 2006 3.0l S-type into reverse, and of course no warnings of close objects. The front ones continue to work fine.
I tried checking the sensors after turning the ignition to position ll and putting the gear lever into reverse, but not a sound. So I replaced the control box but no luck.
I've been waiting to get it into my local garage for them to have a look at it, then last week when reversing in a car park I lost the overhead light and got warning sounds! Since then it's been intermittent, sometimes when I start up and go into reverse there's no beep or light, sometimes there is.
I assume that there's a connection problem, but where?
Any advice would be appreciated.
