Next month my CPO warranty will expire, 2014 XKR convertible dynamic R with 14K miles. On my list of things to have checked is:
1. Infamous water pump for leaks (maybe a pressure test?).
2. Supercharger bearings (cold start rattle sound). No obvious rattle sound present.
2. Overall inspection of generally known things to fail. Any advice?
Other:
I got an alert of the right front wheel tire pressure not being monitored. I assume it is the battery failing in the right front TPMS sensor. After awhile the alert changed to a fault message and intermittently goes away. It hasn't came back in a few days. I assume the battery in the right front TPMS is causing this. I have the original tires and the car is now 6 years old. I understand the TPMS batteries have a life of 6-7 years and the batteries in the sensors are not replaceable. If I can put up with the fault message coming and going I might wait until mid summer to replace the tires with Michelin PS 4S from costco and have them install 4 new TPMS from Jaguar. I've read some after market TPMS sensors aren't reliable so I'll go with OEM. I don't think the cost difference would be much, especially spread out over the life of the sensors. Other than the above the car is performing great.
I agree Sensor is most likely but the intermittent nature of the fault means it could be the front right TPI (Tyre Pressure Initiator) or its harness connector.
The four TPI's on the vehicle are identical and can be swapped between locations to see if the fault also moves.
The TPMS sensors are different for 2014 than earlier model years. Siemens are used on earlier models, but not the 2014. Rockauto comes up with a different TPMS sensors for 2014's.
I would tell the dealership you hear the supercharger bearings and the water pump is leaking. Even if you have to spray radiator fluid in that area. Get it done whether it needs it or not...

You are diabolically clever in applying the Golden Rule!
Yeah if it were me the torsion isolator upgrade is the one I would do and the bushings will be a no-brainer.
Just like Moses mentioned, look at what is flawed in the design and what will go bad in 40,000 miles. I dont know what that could be.
Be careful, dont just replace something because you can get it free- you may be replacing a component that last 60,000 miles with one that lasts 20,000.

@TexasTraveler mentioned; bushings. Is that a warranty item? If so, I would pre-deliver the service manager's favorite bottle and make sure it gets done! Would really make the car drive newer.
Yes, supercharger torsion isolator, and water pump are the obvious. I'll have them check the bushings for defects and premature wear (may not be a warranty item).

Yep, most of the codgers on here have old cars...lol
When I bought my ride I also bought a 2nd set of Vulcan alloys (for winter rubber never fitted) plus 5 x TPM Sensors off ebay, I have used one that was damaged when I had my MPS4S's fitted, I'd taken my TPMS along to change them all but was advised that (with their fancy wireless doohickey analyser) that they were all sitting at over 70% charge, that was when my car was over 4.5yrs old.
Will have a root around in the garage tomorrow and post up the part number, IIRC they were still Siemens and I paid £22 each inc VAT and delivery.

Thanks, Marky. I'll probably order the TPMS sensors from the dealer and have them tested at the dealer for battery capacity. I've read a few posts about after market sensors not being reliable and dated several years old. Given the hassle and expense of replacing them it is not a part one wants to try to save a couple of dollars on.
No am not talking about aftermarket but genuine LR/Jag
Why get from a dealer, jaguar originals are at a fraction of the price on ebay. Part numbers GX631A159AA / C2D47173, the link below are the ones I have and are the factory fitment, would be interested to learn what your dealer will charge you for the whole set?

I believe the North American ones use a different frequency. Shipping from the UK is unreasonably expensive, ie. to ship the above sensors to me in Canada would cost more than the item being shipped and I would need to pay for duties and sales tax of 15% on top of everything. The final price would be 3 Xs the value of the item. I looked at shipping other items from the UK and it is next to impossible to ship something at a reasonable price. To ship something out of China is next to nothing and a lot of the time is free. However, the quality is head and miss (definitely not TPMS sensors). Then again, I purchased a used good condition complete shift actuator from someone in the UK. It arrived and was not the same one as advertised (many scratches marks etc). I returned it with out a tracking number, because of the high shipping costs, and never received a refund (can't trust anyone).
As mentioned before if I buy the sensors from the dealer they can check them for battery charge and date. If I have a problem it will be easy to reorder. For the little price difference it is good insurance to know what you are buying and having the direct warranty from the dealer is well worth the price difference compared to messing with bad sensors in your wheels and having to do it all over again and again...
Can you get a TPMS disable dongle for the XK? I have seen them on Aston's as a plug-in hardware. Computer thinks TPMS is fine, but is not actually being monitored.

I take it you don't believe in karma:-)
Yep a little eye dropper with coolant into the weep hole should do it. Do it now so it doesn't look too fresh. Take a wee bit of coolant out of the reservoir and complain you have to keep topping it off. A few drops on the manifold will guarantee the odor in the engine bay is distinct.
Me personally, would leave well enough alone. All WP's are not defective and once you start replacing ****, you can create a whole new series of problems. The new pumps are nothing to brag about and people are still complaining about them on the F-Type forum, so makes me wonder which version Jaguar is using now. A pressure test is the smart move.
Also, didn't you hear some rattling up at the tensioner or was that on an earlier 5.0 model you used to own?
Regarding bushings, most likely those are normal wear and tear but I recall reading one forum member saying his warranty company replaced them. I find it hard to believe unless they were damaged.
Who is the warranty with? Dealerships are your advocate when it comes to warranty work. They want to find the defects too.

I have not gone on the F Type forums, so I'm not aware of their WP issues. However, for the XK 2010-2015, I believe the very last update for the water pump was 2015. I don't remember seeing any owner (on this forum) with the latest version of pump having issues with it leaking, unless possibly there was an inproper install? There is no question that the early WPs were defective and if the OP can get it done, go for it. Important thing to consider is getting a competent tech to do the install so as not to cause any "collateral damage" with any of the numerous plastic connectors and lines. Good luck.
I can't stand behind fraudulent behavior. (I wouldn't like it if someone did that to me)
But If there are legitimate complaints, better yet, previously documented; I'd go along with that. The rattle/wobble in the supercharger may qualify.
Also, aren't bushings, brakes, yada yada, a wear item... Just go for the 160? point inspection. Take the car there the day before its booked so that it sits overnight at the yard... then get there in the morning to highlight complaints when they start her up for the first time.

One of many thread on the F-Type forum but irrelevant really and I absolutely agree with your comment regarding a competent mechanic. I had some basic body work done last fall and after I brought the car home, I found the wheel well misaligned, the wrong clips used in the wrong place and the window well tore screws were used in the engine bay and the engine bay body mount crews were in the wheel well and one fog light was only partially installed.
I don't do body work but for God sakes, this was just so basic....
CPO final service check--seeking advice.
You are diabolically clever in applying the Golden Rule!
