Took my 2017 Jaguar Xe 35t Sport AWD in because every single dtc was showing up on the dashboard. It got so bad that I could not even switch between eco and sport mode. ABS was gone and etc.

Dealer advised that they swapped out the O2 sensor and cleared the codes. Picked up the next day and while driving all the codes came back.
​​​​​​The second time I took the vehicle, I was told that the windshield was not OEM and had to be replaced in order to recalibrate the cameras since those were the only warning lights coming on the second time around. After installing the new windshield they noticed that whoever installed the previous windshield, they

Missing sensor.


lost a sensor and did not replace it.
Now the vehicle is throwing DTCs again. I will attach the picture. Have any of you go e through such an ordeal because the dealership is at a loss of what to do next.

Sent to me by the service advisor.

That plug is most likely for the rain/light sensor - has this been fitted yet??

As for the ABS - its logged in PCM and ABS, what did the dealer do with this, did they check it?? Was this code from before as well?

The U0001-81 is logged because there is another control module on the High Speed CAN network giving incorrect serial data - the dealer should be able to see what other modules might have codes, one possibly saying " not configured"

It's also possible that you may have several modules, such as ABS, IPMA and the PCM as shown in the picture are due for software updates

 

Thanks! I'll talk to the service advisor and make sure they see this. I can't believe this has been going on for more than 3 weeks now.

 

If it doesn't work out at the dealership, anyone know of a jaguar mechanic that would know what to do in the south Florida/ Miami area?

 

First thing to check when you see multiple codes like that is the health of the battery.

 

The dealer was able to clear all codes and even checked the entire wiring harness. The codes cleared up for a day and came right back. Any idea what it could be? Is this vehicle known for this issue?

 

The XE is battery sensitive, so I second the suggestion. On mine the ECO Start/Stop function quit and it was traced to the battery. They replaced it and reset the battery monitor. No issues since.

 

Well, I went to AutoZone to get a battery check and the reader would stop at 15% when connected. We disconnected the battery and rechecked the battery and it was fully charged and in great condition. Once we re connected the battery, all the codes cleared up. So I'm lost for words now.

 

Wonder if that reset the battery monitor...

 

No clue but I'll see if they stayed off once I go out for a drive today. I'll keep everyone posted.

 

Well, the warning lights are back on. This vehicle has become the biggest mistake as a purchase.

 

Would installing a ctek be a good idea for this vehicle?
Disconnected the battery and the faults are gone again.

 

This is the battery currently installed in my XE. Is this the right one?

 

Not sure, you can hit the diehard site and put your car in. See if this battery comes up...

 

It's not. Guess I found the problem.

 

Potentially, I would still push on the Jag service folks to diagnose. What is the difference in that battery ratings and what is your car is supposed to have?

 

800CC vs 850CC
That's the only difference I see.

 

I wouldn't think that is significant, but again I would stand on the dealer's chest and demand they fix it or return your money. Don't know about the lemon laws in your state.

 

They don't have loaners u til the 29th so I'll wait till then.
They changed the wheel speed sensor so it must be a grounding issue.

 

Well, drove my car today because the DTC were still on yesterday and today they were gone. This issue keeps getting stranger and stranger. Let's see how long it lasts this time.
