I am wondering about how the 12v battery is charged. Is it charged when charging the high voltage battery, or is it charged while driving the car... and does this also work when only driving electric.... and what if you don't drive much. Should you charge the 12v battery manually with a charger?

 

I'm guessing the car would force the engine to start to charge the battery up when needed

 

If your on Pivi I’d reset the software on it and see if that fixes things. Do note there is a bug with Pivi that prevents the car going back to EV mode once the engine is started unless you turn the car off and on.

 

Tried resetting PIvi pro, and also updated to latest software

 

I have already mentioned it before, the 12v battery charge depends on the converter, the vehicle has a 48v starter alternator in the gearbox, if the 12v battery charge is insufficient the vehicle will begin to give problems in the systems that It depends on that line of current that they are all.

 

Good info!

In the drawing it says that the integrated charger has a dc to dc converter to charge the 12v battery from the high voltage system. If i understand this correctly it wouldn’t be neccessary to charge your 12v battery with a ctek charger as long as you keep the high voltage system sufficiently charged. Would be a bit strange if it wouldn’t i think

 

Right, MHEV and PHEV vehicles have the same 12v battery charging problems because the charging system is the same system.

 

Ok so the car went in yesterday, with the problems I described. (EV Temporality unavailable and Special Programs wasn't available)

Luckily the fault happened when the service guy was taking it round, so was able to connect it up to the computer and also had RR technicians working on it remotely

After having it for a full day, says it needs a new EV motor which they have ordered and should be here in a couple of days

 

Hi all, I'm also having the same "EV Temporarily unavailable " message sometimes, the car always starts with the ICE, never the EV mode even if the battery is 100% charged (or any other charge level), it also doesn't matter if I select the EV mode or Hybride mode, only way so far is to stop the car, turn off the ignition and start the car again, it will then usually switch to EV mode. The "EV Temporarily unavailable" seems to have disappeared since software version 2.1.0e P2c4 (13 August 2021), but it still won't switch to EV when selected, still have to stop and start the car.

Same here

 

Car has gone in today for a new EV motor, just phoned to say they haven't finished so will need the car till tomorrow 😤

Work been carried out doesn't sound cheap either, RR are saying the new EV Motor is 8K

 

So got the car back yesterday after RR having it for 3 days.

The car now powers itself with the EV motor, but I've noticed that the car always starts with the ICE motor, If you ask it to go into EV just says its "EV Temporarily unavailable " then switches to EV mode after a mile or so, has anyone else noticed this?

Really disappointing, because when I received the car it was perfect. Always started with the EV motor if it had charge, they'd be times were i wouldn't use the ICE for a week as i don't do that many miles

Perhaps give it some time? Maybe they did a software update as well and I've noted that after such mine starts with the ICE for a bit,sometimes refusing to go into EV mode at all. Settles itself out after couple of journeys,

 

So the car was at the dealer today and it turns out the temperature sensor in the HV battery has failed causing the EV temporary unavailable message. The new part has been ordered, they don't know when it will arrive. Hope that will resolve the issue, really like the electric drive, very smooth and cost effective with today's fuel prices

 

Mine seems to start with combustion engine all the time now, although it reverts to ev quite soon after slowing down and driving gently. That’s without switching off and restarting. I'm sure it used to drive away on ev before and wondered if it was outside temperature dependant making sure that the ic engine was warmed up ready to take up the load if needed. Such a physically small engine would only need a few minutes running to warm up. However, I’m only guessing and it would be good to have a definitive answer.

Booked mine back in for the 13/9/2021, hoping they can find the issue..... Car drives totally different now, compared to when I first got it, the car was perfect!

 

Hey Code Monkey, is your car fine now?

 

I've had the P300e since Nov 2020 and done 7500 miles. I find that on start up at the moment, it usually always fires up the ICE and after a couple of mins running the EV then takes over. Similar to other reports, it used to always start on EV. So I'm not sure what's changed?

 

See my note below, there is a problem with the electrics on the first gen and if a SW updated has been applied they are definitely behaving differently. JLR won’t admit to it, nor will the dealership, but there has been a change pushed though that changes the performance of the car completely.

 

Probably nothing to do with it, but...
I've always wondered how the ICE will fair if it's not used often. Engines need to be turned over and have the oil etc. circulated. Have LR applied a SOTA update to introduce this I wonder?

 

I also own a ’21 P300e and from the latest software update (Septembe) it doesn’t start in EV mode. Someone else suggested to switch off the ventilation. I tried it out and now it will drive away in EV mode right away. But as soon as I turn on the blower it will fire up the ICE. Maybe it is a software issue? My dealer is still figuring it out…

 

Mines still with the dealer for this. It's not been touched for the last week - suggesting perhaps they don't know what's going on.

 

So a heating unit for the batteries was replaced and I got the car back. It did drove off in EV, so I was very happy, but after a couple of 100 meters it switched back to the ICE, I did not put my foot down and the batteries were charged. It did not even switch back to EV when I stopped and started the car unfortunately. Now, after about two weeks the EV mode seems to be getting a lot better, just like it did when I got the car. Just when I felt happy that the EV behavior got much better I got an engine warning light and on top of that a software update ready for installation. The car is still running fine, so I'm a bit hesitant to install the software update. Today a friend is bringing a tool that might tell us what the problem with the engine is, had it once before and that turned out to be a communication error between modules.

 

I’ve just started to have this problem over the last few weeks. It used to start in EV mode and I always used that for short journeys. Now always starts with ICE and get the message EV temporarily unavailable when trying to set EV Until I’ve been driving for a bit. I wondered if it’s down to the cooler weather and the ICE needs to reach a min temp to be able to function efficiently. However I don’t remember any problems last winter when I got it. Going in for its first annual service in a few weeks so I’ll mention it then.

Sales man told when he delivered me the car, that i can use "Wake up timer" function from remote app or car's settings to "pre-heat" car batteries.
The batteries are working in about 23C degrees. So when you have to leave and the temperature is under or over 23 the car have to heat or cool the batteries to work as fully EV.
For example you can hear the coolant pump and see the bubbles in coolant container under the bonet when you are charging your car.

 

ooo you wake the car up ... the amount of times I've gone to pre heat and the cars asleep and I can't lol that's new..

 

 

My Evoque hybrid is a year old and has covered less than 7000 miles. I’ve just had a run of similar issues, particularly the “ EV temporarily not available” and multiple drive functions not available. After several visits and finally calling out LR recovery it went in and was diagnosed with a faulty HV Heater. Heater replaced, SW updated all seemed ok, but within 5 miles same issues again. Re-diagnosed and the error codes show numerous electrical units are failing at the same time! JLR are being unhelpful, the dealership are being vague and seem to be stumbling around trying to get to the bottom of issues. Would love to hear if anyone else has experienced similar issues and has had a fix provided.

 

How come you didn't join the forum a year ago when your car was running great?

 

It's such a shame that this forum has deteriorated so badly when it comes to the P300e, when I first came on here I was asking about towing with one which I received some interesting responses, since then it's progressively got worse, there are issues for sure but a lot of the issues are down to user ignorance and how the car operates. To be brutally honest the majority of users who complain have got the wrong car they should have gone full EV, trying to make this car an all EV does not work.

But then again an EV car is not without issues, recently reported an individual had his Tesla destroyed as he was deeply annoyed with Tesla after been give a bill for $22K for a new set of batteries.

If we're to believe the owner of this Model S, he was quoted nearly $23,000 for a new battery, so instead of paying up, he destroyed the EV

User ignorance ? My a*se...

If the car wasn't designed to operate in EV only mode then it shouldn't have had the option to select it. You can't blame users if that option stops working over time due to system faults.
I operated mine mostly in hybrid mode and as I have documented the way it operated changed and it eventually broke down to the point that a rejection was accepted. This wasn't down to ignorance on my part it was down to flashing warning lights and a LR assist technician declaring there were multiple issues not just with the EV system but with the petrol engine also. The loan vehicle also developed faults.
The forum hasn't deteriorated it's the reliability of an increasing number of P300e's that has with more and more owners reporting their dissatisfaction.
So far your car @RobS has worked well for you, don't lash out with accusations of "ignorance" because others haven't been so lucky and have taken to this forum to report it

 

When you see user coming on here and stating "It's an EV so therefore it I will press the EV button" even if the car doesn't allow it - what would you call that. As for the function of EV then I would agree that LR are solely to blame for selling / promoting a car that will do this magical 34 miles in EV alone but in fact will only do this magical figure when all the ducks are in a row and the car is happy to provide it.

For me, maybe I'm lucky, who knows / who cares - when I went to buy a replacement for my Countryman that had been screwed up by BMW, I wasn't interested in the P300e range in EV hence my original question posted on here about towing with a P300e, which has been proved to be pretty good. To be honest if it had been a P250 I would have taken it as I really didn't know the Evoque that well but the car came with a towing hitch which was more important to me.

One thing is for sure I am not lashing out, just stating the obvious. For sure there is a conclusion with regard to the older and newer models and the issues which are reported - which I've stated previously, it's predominately the MY20's that have issues and as someone recently stated (a newcomer) there is something strange going on with the software up-dates and how the older vehicles take them on-board.

So at the moment we have around 10 - 15 people with issues, not sure what to total sales are for P300e are so difficult to say if the numbers are large or not, is that a lot - yes for a forum but a drop in the Ocean for LR.

Just remember this is not just a P300e issue, it's most of the plug-ins that JLR offer.

 

👍

 

is hoping they know what they're doing now 🤞 or isn't going to read any more 😂

 

Ok
