Good afternoon All,

Not that I would wish the issue on anyone but hopefully someone has some experience and can help with my problem. 2012 xf with 82k on it. Had 0 issues with it until last 2k. Then 2 fuel injectors went as well as water pump and related hoses. Didn’t seem to shift right after getting back for these problems, which occurred almost simultaneously. Problem seemed intermittent and between 1st and 2nd gear only. Then last week the check engine light came on and the gearbox fault warning has popped up a few times. Car would either not shift out of first gear or at all on a couple of these occasions. Turn it off and on again and it would shift. Took it to a friend who owns a garage and the following codes came up: P0711, u3000, p0781, u0122, p0103, b1087, u101b, p0500, p0501, u0401. Most all these seem related to lost communication between various components and somewhat support my lay person belief that this seems more electronic than mechanical. Of note is that the back up camera started to not work a week prior. It does display momentarily but then shuts off and says to contact the dealer. Perhaps related to wiring? Also, the battery died during all of the other repairs. Installed new one but seems there is a wiring harness that does not have a home, I am unsure as to whether this is from an unused option or that it may be related to issue as I have heard battery issues causing these types of problems, please see picture, the wires are black and brown with white stripe. Could really use some help and guidance as to whether this is major or perhaps an issue that is well known. Thanks in advance.

A similar question was asked on the F-Type forum. The response was that the electrical connector near the battery is only used during delivery and is never used thereafter. Consequently, that isn’t the cause of your problems.

Coincidentally, I’m looking to purchase a used 2016 XF. AWD. When I took it for a test drive this morning it felt like the transmission and/or transfer case was binding. Initially, it only happened at low speed and when turning the steering wheel. Then, it felt like the brakes were being applied as I was maneuvering into a parking space. The XF I’m considering has a history of the wiring harness being repaired and the A/C condenser being replaced at 22,000 miles. The salesman now tells me the transfer case needs to be replaced. So...I suspect the car was wrecked but not reported.
