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)

Those SC pumps are not the greatest. I would, along with several other forum members, suggest getting an uprated pump.
Someone else will be along soon to give you the brand and part number, and I will also probably buy one, install it after I get my garage furnace fully installed (a week, maybe).
I had the same on my old 2008 4.2 XKR. In my case the S/C coolant pump fuse was blown, I changed it and drove for a few miles then pulled it out, blown again. Tried a third fuse with the same result so concluded it was the S/C coolant pump. I ended up getting a standard pump from a breaker and replaced it myself which resolved the issue. There are other parts you can use from the likes of Bosch but none are direct replacements, they'll require some work on wiring, mounting and possibly plumbing to get working. If your car is standard as regards engine performance modifications and you don't live in a hot country then there's likely little benefit in an uprated pump anyway.

One of the first jobs I done on my xkr 2011 was to change out the coolant pump as read of problems of failure. Indie done job cost £400 if memory serves me and also used Bosch pump . Just saying

So I get replacing parts for the purposes of upgrading, but I don't see the need to replace parts which work perfectly well with something that works equally well. Yes if you had upgraded pulleys and remapped the ECU, and/or replaced the supercharger or just lived in a very hot climate but your money, your choice I guess. For every one of us that's had this pump fail I'd wager there are a 100 more who's original pumps still work perfectly well, this is not an endemic flaw in the car.
Regards Bosch, I had a SEAT before my first XKR, obviously they're owned by VW/Audi group. I lost count how many Bosch-manufactured parts I changed over the years on that car. The Bosch brand does not equate with "upgrade" in my personal experience.
8bit, for me it's mostly due to the code, but also maintenance. With 60k on the clock, I'll probably work my way round a few bits and bobs to try and avoid future issues.

Like yourself I am high on maintenance , yes I changed mine others could and have said Unnnesasary . Just me I done for peace of mind . Also I changed MY spark plugs at around 60k miles and also supercharged oil and transmission oil and filters ohh also ancillary belts and supercharger belt . Yes my car my money . I make my living of maintaining heating systems . More on here should attempt DIY would make for a better forum instead of battery threads

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.

Belts, oils, spark plugs etc. that's all consumable items; you would expect to change those several times during the life of the car. I wouldn't *expect* to change a secondary coolant pump any more than I'd expect to have to change a wiper motor, screenwash pump, oil pump, ECU etc. etc. For all you know that OE pump could have outlasted the engine of the car. I agree on the peace of mind thing but like I said last time, I'm not sure the S/C pump "issue" is as widespread as all that so I disagree that it should be changed purely as a precaution. The OP however does sound like his has failed though.

From MY experience... those OBD 2 car problem codes DON'T LIE!!!!!!!!!!!Fix that issue and your car should be working fine again.
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.
It is on here so I am assured but to tell the truth I myself do not no were to look . Al I know is if you google up how to change the supercharged oil on a 5l jaguar xkr . You should get a pointer to the :how to .
Just googled up how to change the supercharged oil in a 5l jaguar and the link to this forum clearly pops up . Should be more clearly marked by this forum in stickies s mods please note to help other members . Ta
Restricted performance - P2601
