Yes, if yours is a PHEV version, we might be experiencing the same error. Our MY24 P550e ATB has been to service a week now with a battery/EV fault. PHEV battery error and finally a yellow engine warning light.

Started with an error message in the Remote app after a night charging in our Level 2 DC home charger, and a blinking red led light at the vehicle charging connector: (BTW: The home charger reported that the vehicle had received 100% charging as normal)

It's a Land Rover after all

 

What level 2 charger do you use?

 

Luckily your info-line says that you have a trusty L322 TDV8 to fall back on! 😀
Let's hope it's a software/calibration issue.

Merry Xmas from a snowy Stockholm!

Yes, that is just a fantastic vehicle! Classy looks, sturdy, comfortable and versatile!

What level 2 charger do you use?

We use a Zaptec Go charger.

But, @CMAC-SD, have you reported this error to your dealer?

 

My vehicle is the Range Rover Autobiography LWB (Seven Seats) 4.4 litre V8 530PS. The fault registered last night so I have not reported the dealer yet as they are closed. I’m just trying to figure out what the fault means as the LR app shows the status as “no issues” and the “health of your vehicle” app similarly shows nothing. I’ve been away from the brand for several years and forgot that one needs a high level of engagement with the vehicle to enjoy it. I’m just not the drive it and hope the fault just goes away type and the dealer is about 90 miles away.

 

I had exact same issue with mine too 2 nights ago - a P400e First Edition. This is wierd, sounds maybe like software issue if we all getting it ?? Like yourself, the app showed no issues. My car has since shutdown completely. I cant get in touch with dealer as they are closed but will do tomorrow. Lets keep in touch!!

 

Here’s the update on mine. The dealer was able to fix the issue. I don’t have the service documentation yet but they explained that it related to the coolant for the EV system. I have since driven it almost 1000 miles on vacation and everything seems fine.

 

Thanks and that is great. Mine is just gone to dealers now as it was closed over new years/Christmas. Good news yours is sorted and hopefully mine will be fixed soon enough

 

On the hybrid it is most likely the high voltage heater/cooler. There have been a lot of reported problems and ready replacements in UK. It is a Bosch made part and is used across different brands - not just JLR. Tell tale signs are engine used at first start up if internal heating control set high.

 

I have the same issue BUT service said they refilled the coolant and now it should work. Unfortunatelly after 4 hours of driving the issue returned. I am pissed off as it pops up every few minutes again and again (I was driving 10 hours). Anybody has the same after coolant refill?

 

How did you guys get on with the above, just happened to one of my P440e's (a year old).

 

We got our car back mid June, after 6 months with the car back at the dealer! They had to replace "Module 6" in the PHEV battery. It's worked flawlessly since we got it back - happy for that!

 

My p400e is also playing up, and has done a few times over the past 6 months. I’ve noticed that when the electric is partially charged, it brings up all kinds of random glitches and warning lights and when it runs down to 0 electric miles, and I vacate the car, lock it then get back in after a few minutes, the car is completely fine running on gas without any warning lights or issues! I’m just going to refrain from charging mine until I can get the dealership to take a look. This is my first hybrid Range Rover and I’ve never had a problem with my previous gas only models!

 

Were you able to get it to the dealership to get it checked? Did they fix the issue for you? I am having the same issue on my 2025 RR PHEV.

 

I have 24 550e delivered 1/2024. It had low battery coolant on a new car and showed electrical system fault. I filled up the coolant and has been fine. Been checking the coolant level for possible leak but remains at same level. 550e owner should check the coolant level, especially after getting the truck new. It's located at front left (need to shine flashlight)

 

2025 P550e with error message "ev system fault detected" I drove to the dealership end of last week when the message appeared and then the error message went away once at the dealer. They didn't have a bigger size loaner until Dec. 5th. Also one of their techs who works on the p550e was out on vacation. I drove a few hundred miles this weekend and all seems normal.

 

Did the dealership take it on even when the warning message disappeared? I have the exact same thing happen. I got the warning message and it disappeared right away like nothing happened.

 

It could be low High Voltage Coolant Fluid level.

 

I am planning on taking it in on Thursday (first time they have availability for a larger loaner) and the error message has not reappeared. Do you think I should still take it in ? Many times on my bmw's an error message popped up and then went away never to return.

 

Def take it in. They should be able to retrieve the history of the errors and diagnose it. It will bite you later if not addressed

 

Hi. Since I have the same issue how did you solve it?

 

what model year and engine trim ?

 

Picked up the vehicle today and they could not duplicate or find an issue..

Here are the details on the work order...
