Any Jag mechanics wanna help me trouble shoot something. It's all started with what should have been a simple battery change. I know I'm missing something small. We have an alltul scanner and today we let the Car know it had a new battery in. I was able to drive it for a 5 or 10 miles and then it started doing this if you see in the video below. Death I let it sit for a while I can drive it for a few miles and then it starts doing this again. I put it on the highway and side streets and it drives fine until this kicks in and kind of puts it in a limp mode. Any ideas? The key fobs are also disengaged. But if I hit the headlight button on the keep up that works.

 

I see a pic, no video.

Details of the car like model and engine will help sort this out.

Changing the battery on this generation of Jags is more complex than expected.

 

Any codes?
Can you DIY anything?
