My dad used to drive a 2004 Jaguar XJ8. He passed away a few years ago, and I’m hoping to keep the car for as long as I can, because it’s beautiful and has much sentimental value. We keep it in very clean condition, but it doesn’t get driven much—I’ve been away at college and my mom drives a different car—so it’s a bit worn and has had problems often.
The latest problem has my mom considering getting rid of it, which I desperately want to avoid, though I know it’s a money hole at this point. The car shows a “restricted performance” warning, and the Jaguar dealer told us the rear electronic module needs replaced, but they don’t have any and don’t know where to order one. I’m not super car-literate so I could use some help understanding what this part is, where I could potentially find one (I did find this—does it look correct?), and any general advice you may have on upkeep.
Thank you so much for reading and offering any help at all!
