Hi my sport supercharged is in the vin range for the aux pump problem when I tow my van I get the restricted performance and the p code that tells me the pump issue I can either recycle the ignition and it's ok for a. It on motorway but comes back .Do I have to change h the pump or can I just reverse the wires and is there anyway to find out first if it has had the work done thanks on advance

Just reverse wires.

I guess you might see some bodgry if it's been done???

It is recommended it is replaced. Apparently it fails rather quickly after reversing the wires. Check out my gallery. It has the tsb. MY12 RRS HSE

Don't quite understand why it would fail if you just reversed the wires to be honest and can't see anything on tsb about reversing the wires or am I just being a bit thick

Hello geoff
The below describes the wiring orientation on the pump connector. (From the tsb (there are a couple so check you are on the correct one 😋

Correct orientation Range Rover Sport (LS) is:
• Black (B) wire in Cavity 1 connected to "-" pump
connection
• Brown and Purple (NP) wire in Cavity 2 connected
to "+" pump connection
Correct orientation for Range Rover (LM) is:
• Brown (N) wire in Cavity 1 connected to "-" pump
connection
• Red and White (RW) wire in Cavity 2 connected to
"+" pump connection
3. If the wires are crossed, use terminal extractor tool
YRW9000010 from the Harness Repair Kit and swap
cavity 1 and cavity 2 wires to the positions indicated above. MY12 RRS HSE

Thanks shep what's the difference between a ls and a lm Range Rover Tia

LS is your sport

Thanks everyone for info where is best place to get a new pump

I got mine approx 7 years ago. It was only £119 from Landrover. Which isnt to bad considering its on permanently. I think they are nearer 150 now, but definitely worth checking with the dealers first, I've found loads of parts cheaper from Landrover rather than eBay etc. May be worth giving Duckworth a pm. MY12 RRS HSE

Just pm'd him seen them on the bay for £105 and stated as genuine
Thanks

Well just changed my pump and wires still find it hard to believe that this has not been sorted on a 12 year old car it looked at when i started to take it all apart it did actually look like the pump was disconnected
