If it was me, seeing as all 4 front sensors are new, and the OP states the loom in the bumper is new. I would run 2 power wires from the module to the new loom connector and see what happens as I think that’s the issue. 2019 5.0 SC SVA (Current)

2 wires from the front of the car to the rear ?

Pull the brown and black wires (pin 1 and 2) from Connector 1457 (module connector) and connect in 2 lengths of wire to the new front loom connector 2278 pin 1 & 3 (assuming that the front loom is new as stated in the first post). 2019 5.0 SC SVA (Current)

Not a electrician but doesn't make sense to me, connector C2245R shown as 14 pin connector, wiring diagram shows blue wire pin no.19. C2245L shows 24 pin connector, unless I'm reading it all wrong which is quite possible.

I remembered I had access to some diagrams at work and I think the wiring diagrams shown previously are later diagrams. The 2008 diagram I have access to shows 3 wires to each sensor from the module whereas the later version has 2 common wires from the module which then splits between the 4 sensors.

The failure mode (of only certain sensors grenading) only really makes sense if the wiring diagram matches yours - assuming it's a short; with the commoned up feeds in the later wiring, you'd expect them all to pop at the same time.. 2014 BMW 530d Touring, 2006 BMW 650i, 2018 Mini Cooper S

Hopefully the OP can confirm what wiring diagram is what he has, it should be the one I posted but the diagrams have been wrong in the past. If it’s the 2 middle ones blowing, it’s a bit odd as they are almost 2 separate circuits.

Can the OP post a photo of the old loom? 2019 5.0 SC SVA (Current)

Sorry, my bad - luckily you have plenty of diagrams now

No problem mate, we just need the OP to confirm the correct diagram. 2019 5.0 SC SVA (Current)

Well I have fitted the rear original sensors to the front. Fitted more replacements to the rear to see what happens. I ordered 4 which went missing, Seller resent another 4 then the originals turned up. (Lucky me) so still have spare. So far all good Will update in a few days, They never last longer than that. 2008 range rover sport 2.7 hse

Col, is that the 2010 MY location diagram? 2005 to 2009 is likely different.

The 2005 to 2009 diagram I have access to shows power to each sensor direct from the module rather than a single feed split between the 4 sensors. That will make a difference when fault finding. 2019 5.0 SC SVA (Current)

A wee update and a good lesson to learn.
I swapped the rear sensors to the front, Fitted the front replacements to the rear. Then pop one of the rear sensors popped.
I have bought 4 genuine sensors. All good now.
It looks like someone on flebay has sold me cheapo sensors at an expensive price £21 each.
Will now be sending back for a refund.
Thanks for all the advice from everyone. 2008 range rover sport 2.7 hse

If you have no luck with a refund, use the eBay dispute route, were the OEM sensors much more expensive? 2019 5.0 SC SVA (Current)

I paid £124.50 for the four. I was lucky as a local garage had a set ordered for someone else who never came back. Worth every penny.
I have returned the Ebay ones. Will wait and see if I have to fight for the refund. 2008 range rover sport 2.7 hse
