In a 2013 Sportbrake there should be 2 batteries in the boot. A standard large size one and a smaller one.

There is a smaller battery the other side of the big battery. If they are good then the car will stop-start (some have reported that if the a/c has lost its charge the stop-start will not work). However, some are nit keen on this and it is possible to nobble it.

Enjoy the car - the 3.0 S is a very nice car.

I get brake judder on my XFS, given up trying to cure it, it's a "characteristic" of the car, seems quite a few XF's suffer this. But as you were complaining the discs are worn, you'll be fitting new ones anyway, see if the judder goes away!

This is reminding of a time 9 years ago when I brought home a 4 year old lovely X-Type 2.2SE Estate in mint condition with 134K on the clock. Joining a forum, finding out all about it, learning, getting the Jag workshop manual and wiring diagrams etc.
It is now on 296K miles. In that time I have changed the clutch/DMF 3times, the injectors and diesel pump once, brakes loads of times including calipers. Its still shiny, and still goes well and passed its last MOT with no advisories. I do all my own work.
Starting all over again with the XF..............

I too try to do all my own work, servicing and repairs, I have a loathing for most dealers, their charges and attitude to customers. I'd happily use a specialist of course. Ooooo, white, nice! My XKR is also white. Looks very, very nice.

Just reading the finer points of the service it just had and it includes 'renewal of brake fluid'. Silver lining. Saves me having to do it.

The brake judder has been looked into extensively by Ninjag.

Use the search bar and you should find it easy enough.

Whoops, two images!
Anyway the "due for replacement" or "worn" thickness varies with the brake spec (326 mm, 355 mm, 376 mm or 380 mm) but it's the same across all of them - a whopping 2 mm less than new thickness.
I have commented before how this seems to be a ridiculously conservative "worn out and due for replacement" spec, especially for the 380 mm front discs which are 36 mm thick when new. Little risk that you could go to twice as much wear as this (ie 4 mm less thickness than new) with zero problems, with one caveat - in my experience and that of others the inner surfaces of the discs wear around twice as fast as the outers, so 2 mm worn would be roughly 1.3 mm off the inside and .7 mm off the outside.
Point is, these are the factory JLR specs so if any disc is 2 mm or more worn below new thickness it is officially due for replacement, no ifs or buts, and you should be able to legally hold the seller to that.
When I bought my old XFR a few years ago now the seller advised up front that the local JLR dealership had advised him it was due for new brake discs and pads so I offered $2,000 off the asking price and the seller agreed.
Very cool Oz with following up on a chart for him . And others as well ......well done !

Had a Fiat SupermirafiorI when younger. You knew when the discs were worn out because the brake pads flew out under heavy braking.
