Decided to give the AVT pump a go. Seems a copy of the Bosch, with reportedly better performance. They seem to have a few happy customers from aftermarket cooler system scene so will see how it goes.
Can you please share the part numbers. I'm struggling to get the electrical coupler.

If you're using the bosch pump please see my post linked below from December. The AVT pump I believe uses a bespoke connector which comes with the pump or you can buy from their ebay store however I have spoke with them and the AVT connector is not compatible with the Bosch pump.
[QUOTE=8bit;2329920]So yours does sound like it's failed. Try removing the engine cover, take it for a 20 miles or so drive and then check the heat in the engine bay; if the supercharger coolant pump has failed then the charge coolers will be too hot to touch. Normally they'd feel hot but not dangerously hot to touch.
I can drive mine in 50 degree weather for 30 miles or more in a mix of stop and go traffic and open road and the charge coolers are still cool to the touch. They will get luke warm in the higher ambient temperatures but even in the summer are not hot to the touch unless idling for 15 or more minutes. Once traffic moves again they cool down really quickly. I now run a Pierburg pump and separated the charge cooler circuit from the engine coolant circuit . I found that having these separated does make a difference to inlet air temps. An added benefit is extra coolant capacity in the intercooler circuit and most importantly no heat is transferred from the engine coolant circuit to the intercooler circuit when you are in stop and go traffic
I have XKR 2007 4.2l and I think my intercooler waterpump is also on its way out. I got a restricted performance triangle while having some right foot fun. I let the car cool off and drove sedately and the restricted performance triangle disappears.
Doing research on this website it seems like its a common problem with the Jaguar intercooler electric waterpump.
When replacing the intercooler water pump, do I need to remove the bumper or can I gain access from the top or bottom of the car by removing the radiator cover.

When the pump on my old 2008 4.2 failed then the Restricted Performance warning wouldn't go back off just by driving sedately, I'd have to stop and switch the car off for some time. You need to check the car for fault codes, there are lots of reasons it could go into Restricted Performance mode (many of which are more common than a failed S/C coolant pump), without scanning for fault codes and no other visible symptoms you can only guess, really.
As for changing the pump, the workshop manual doesn't tell you to remove the bumper but I found it made the job far easier once I did so I would recommend that if you have to go down this route.

Agreed. You can actually remove the nut from the front without disconnecting the top 2 hoses this way.

That's good to know, I'd already taken those hoses off as per the workshop manual guide before I decided to remove the bumper. If the pump on my current car ever goes then that'll save a fair bit of hassle.
Recent owner of a 2010 5.0 xkr on 60k miles in white. Love the car and seems to run sweet as a nut (most of the time!)
The other week I received "restricted performance". I'd be driving for approx 50 or so miles, stopped for an hour, then within 5 mins of driving again got this code and extremely sluggish performance. No weird smells, sounds, noises. After turning the car off and on again, issue had gone and car performed normally. I thought nothing of it.
Yesterday I had a similar journey, a bit over 50 miles, stopped for a bit, then within 10 mins of driving got the same issue again. As I was on the motorway, I had to drive for about 20 miles or so like this. Again, no weird noises, smells, sounds. Stopped the car and on restart, car was back to normal.
An amazing neighbour plugged the car in for me and the attached codes came up. Interestingly p2601-00 coolant pump control - circuit range/performance. I've just checked fuse 24 in the engine fuse box and the intercooler pump fuse is intact.
Before I get the pump changed, any other ideas on what this could be? I'd have expected the fuse to have gone if the pump had, and expected the issue to kick in sooner and more persistently.
(as an aside, any advice on other codes appreciated)
you know what you really need to do that might even prevent your water pump from going bad all together,put some coolant additive in your coolant like water wetter,super coolant,vp racing coolant performance improvement,or etc.i noticed too that the coolant by itself just isn't enough and that stuff will get hot enough to start busting rubber pipes but imagine what else it could be damaging?The coolant alone before i starting using additives even melted my whole coolant reservoir 1 time on my 2007 Jaguar XKR i use to have and I had to replace it.Ever since i start using cooling additives,I never had a problem with my coolant mechanisms again

Won't cost much to replace so I'll do a full flush and refill also. Thanks for the tip
All on there. I ordered the "focus rs pump" as I found it on ebay at about 80 quid. From the specs and physical inspection of the pumps, they all seem to be the same item
Yeah thats the first thing I did... engine temps were fine, coolant level was good. Just the s/c cooling.
I did rig a 12v battery to the pump and it did run, so thankfully I wont have to replace it or drain the coolant.
Turns out the connector was fried. I pulled it off and the (+) wire broke right off. Not sure how that would be caused but I'll have to get a new connector and maybe some better wires.
It does sit right behind the grille so i'm guessing my weekly car washes were getting it wet.
