could anyone tell me how can i tell which of my sensors is playing up without having to pay some technician £40 to find the fault which sensor as i want to try and figure out which one to replace

Ignition on put into reverse then listen to each sensor, I use a stethoscope the one not ticking is the faulty one. It could also be a wiring fault, corroded connection.. 2008 G4 RRSport TDV8 current

The Vesuvius Orange of your Supercharged signifies it was one of the "First Edition" cars, IIRC 300 in Vesuvius Orange, 300 Black and 300 Silver were built for worldwide sale, so quite rare cars. They were built to celebrate the launch of RRS in 2005. CamelRock's RRS is however even rarer! It is one of only about 8 or 10 built for the G4 Challenge (that was then cancelled!) and is a TDv8 (there were a few more 2.7TDv's too, but not many) and they are all painted in soild Tangiers Orange, yours is a Chromaflair paint that will change colour quite alarmingly when the sun comes out! CamelRocks car should have come with a truckload of additional kit stowed on an Expedition Roofrack, including a mountain bike, canoe, tent............... 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it

Also in my garage is a 1996 TDi300 Defender 90 County HT made into a fake CSW

Using a stethoscope (automotive not medical) is the first check I do with customers cars you can hear them tick, if 1 isn't then that's the faulty one unless as I've said before the fault lies elseware wireing or module.
As I understand it there is only one fully kitted G4 TDV8 mine was next in line to be fitted but the event was as you say cancelled saw only had the decales fitted. 2008 G4 RRSport TDV8 current

i haven't got the sensor yet but is it easy to replace the rear sensor? do you have to remove the bumper?

I think so yes, only done one on a D3 which basically the same and had to remove the bumper. 2008 G4 RRSport TDV8 current

Clean it from the backside with a high pressure-washer.. Mine was full of mud there and that gave the error..

Done 2 rear and 1 front sensor couple months ago, rear bumper off, there is a great step by step on forum somewere, you should hear ticking if place ear next to each sensor.

i tried putting my ear next to sensors but just don't hear anything - but so far the sensors have been working ok but i do have the sensor in hand just in case it does play up again
