Issue: Red low coolant warning message displayed on the Instrument Cluster intermittently. Vehicle shows no indication that the coolant is low and no leaks can be found from the coolant systems.

NOTE – the concern detailed in this SSM is only applicable to Jaguar I-Pace 2019MY vehicles up to: SADHC2S12K1F72770

Cause: Battery expansion tank (T4K9051) and Electric Drive Unit expansion tank (T4K9050) float stem area showed that the float stop was not fully formed allowing the float top to travel further than specified.

Action:

RHD vehicles: Check the coolant level in Battery expansion tank and RHD Electric Drive Unit expansion tank.
Visually inspect coolant systems for leaks.
Inspect coolant level sensor wiring harnesses and connectors.
If no fault can be found for a low coolant warning message: Replace Battery expansion (T4K9051) and RHD Electric Drive Unit expansion tank (T4K9050)


LHD vehicles: Check the coolant level in Battery expansion tank.
Visually inspect coolant systems for leaks.
Inspect coolant level sensor wiring harnesses and connectors.
If no fault can be found for a low coolant warning message: Replace Battery expansion tank (T4K9051)

Note: Coolant tanks were quarantined and quality assured parts can be identified from Date Clocks shown on mouldings = Feb 2019 onwards
Please see example of Date Clock Locations: Battery expansion tank.pdf, RHD Electric Drive Unit expansion tank.pdf

Removal and Installation information is in TOPIx Workshop Manual:

Thanks for posting this. I had my car booked in for a tow bar fitting, H264, and the first service, when I saw this issue a few days before. I duly added it to the list and the dealer has now sorted it out according to the fix posted above.

Would you be able to tell me how long the dealer took to resolve the issue, I've just had my car back from the dealership after they took 3 months fixing it, its been a aeek since I've had it back and now have this popping up

I had this some time ago. Called jaguar assistance after seeing this. He just topped it up and it's been ok since. He told me that they have been calibrated wrongly just need to be near the max mark mine was just above the min mark.

Mine had the replacement parts fitted as per the bulletin.

My car was in for two days - the tow bar fitting and software update would have taken the bulk of that time, suggesting that the tank replacement is an easy job.

Hi Mine has just started showing this on the dashboard.

Please may someone tell me where to look so I may check it myself for leaks and level?

Thanks

You need to open the bonnet and look at the end of to "motor room" where you will see the side of 2-3 fluid containers. To add any fluid you need to pop up the small covers just below the windscreen by pressing from underneath. Done this to check my brake fluid level as it is not visible from outside of the brake fluid container...

Thanks Ingenioren. I've just checked and topped mine up. Since Jaguar are closed I had to go to Halfords. Finding the right antifreeze type was a challenge.

Eventually I found Mobil™ Antifreeze Advanced which is an oat based mix .
