As title suggests, i'm pretty sure my power steering has just gone and died on me or atleast, is on its way.

Context; I backed off the driveway this morning and when I went to turn the wheel I found it very heavy as in i'm struggling to move it levels of heavy. I pulled back onto the drive and parked the car. With the engine running I gave the wheel the slightest pull and heard a loud whining/whirring noise and the wheel flicked back into the center position. Tried this in the opposite direction with the same result.

I assumed i'd lost my power steering fluid only to learn that all Jaguars from 2016 onwards (as far as I can tell) use electronic power steering. I can't find anything in the owners handbook about this and being Sunday, zero garages I can get the car recovered to.

Is there anything dumb like a low battery that could cause the issue or some kind of sensor that might've failed?

Car is a 2016 V6 F-Type. Car started up perfectly fine and didn't notice any issues until I went to turn. No messages or warnings on dash about the power steering.

Any and all info appreciated.

 

2016 is definitely electric-assist P/S but the copy of the service manual I have looks to be for hydraulic. The troubleshooting section isn't any use for electric. Because it's computer-controlled, I'd expect to see at least one DTC on a failure like that. Do you have a way to read codes? If you do, remember to reset the battery module (disconnect battery for ten seconds or so) after disconnecting the reader, unless you're certain the reader you're using properly closes the session.
