The issue affects a range of JLR PHEV vehicles which seemingly all use the same heater. The full range is in this document; https://static.nhtsa.gov/odi/tsbs/2020/MC-10185391-0001.pdfJust been on the Evoque forum where owners with same P300e set up are experiencing exactly same problems.
The heater was replaced with new and car is now working fine.My p300e has had a day in the dealership today with their EV Technician. The "EV Temporarily Not Available" issue has been diagnosed as a fault with the High Voltage Coolant Heater (thanks FThewlis, your post certainly helped hasten the diagnosis). Again the part is on back order, a date couldn't be provided. As the works are expected to take 10 hours, mine is preliminary booked in for just before xmas when they have a loan car available.
Definitely Webasto - it’s certainly possible? Other manufacturers also make this type of heater.
Got ours back today after first service and HV coolant heater replacement. Pleased to report the car is back to the way it should be. IE climate and EV working at the same time.I got OS 2.1.6 on 3rd Nov. I would say there is a slight improvement in that I can get onto battery earlier and stay on it for longer. However it is far from the original and expected: turn car on and drive on battery until it runs out.
Mine went into the dealership today and they have diagnosed the coolant heater as expected. As other posters, there is no date on availability of the part as yet.
I have had similar issues. The car seemed to work ok for a while and now it is 99% in ICE mode with "EV temporarily unavailable" message when try to force into EV mode. I took it to the LandRover dealership and they say there is no issue and car is working as it is supposed to! It is booked in again as I didn't accept their response. Really bad experience and the reaction of Land Rover in Slough has been very disappointing.Good Morning,
I'm curious to see if anyone has had the same experience with their P300e.
This morning, while in Hybrid mode, I noticed that the petrol engine was running rather than the EV as it normally does on short trips. After about 15 mins, I pulled up at some lights and switched it off and then back on again. The car pulls away in EV and all seemed fine. A little later the petrol cuts in again and remains on, I try and force EV but get the following message "EV temporarily not available". Once again, pull over, switch off the car, switch it back on, EV works fine until the petrol cuts in again and we are back into the same cycle.
Interestingly, the EV is working because if you put your foot down or go up a hill, you feel and see the EV engine cut in to support the petrol.
Has anyone had anything similar happen with their P300e?
