Sir, you might have saved me a lot of trouble! Gotta verify my thesis, though. I also got the Battery not charging error and several other error messages following. As I saw your video, I remembered that my N/A 5.0 V8 did a whistling kind of noise yesterday. That could indicate a problem somewhere in the belt-drive system. Thanks for your video!

All the same issues with my 2013. Thank you! I'm gonna look into this harmony balancer.

Great advice, thank you, (UK)

thanks sir for the video i own a 2013 xj with the same engine 2.0 and i just had that problem and the steering wheel not turning and air condition is getting hot and i just smell a burning rubber from the engine bay so i just noticed that the belt is slipping so i will change the belt and the pully hopefully it gets fixed

Just had this light pop up on my 15’ 3.0 I’m sure the dealer wants the maximum amount to fix

@kelvin portis did your gearshift mess up also

You have made me think. I've had the battery not charging going on and off for months. The start stop switches itself off and sometimes the car won't start until the 5 attempt. Jaguar dealer says maybe the bms system and a module needs changing - cost £1400. Your video makes me think something else going on.
