Tesla Supercharger Issue MG5 LR

As an aside, I thought I would take a little advice on the Consumer Rights Act of 2015 from Blackbelt barrister on YT. It would seem that if we consider the inability to charge at a Supercharger as a fault, then we have 30 days and possibly up to 6 months in certain cases to reject the car.

The question is, can this be described as a fault. To my mind, it probably is. Since the car has a CCS plug socket, the average consumer would expect to use any CCS charger to charge the car and if it does not work then the car is faulty. It is clear that the car CAN work but only if you force an upgrade out of MG either by negotiation or by paying them for the privilege.

I had a discussion with my salesperson before I bought it. I said I'd be able to use Superchargers and he said that Tesla Superchargers are not open to anything but Teslas. I said that was wrong and they were opening up the network and was then told he hadn't heard of that. (ignorance is no defence). He did not tell me at that, or any other point, that MG5s cannot charge from Superchargers. I'll bet there are a few others out there that were in the same position. It was the same for the sales manager. He said he didn't know either.

Its clear that what we have here is that the dealers do not know about the advances in the charging marketplace (or are pleading ignorance) and expect the consumer to agree with them. This is not the case. The well-informed consumer will have researched the different sockets and chargers available as 'road trip' charging is a major part of the feasibility study before purchase. If not from the MG web site that it gives rapid charging figures for 'public chargers' - there's no asterisk that tells us which networks are unsupported or need an 'optional upgrade'.

Well, that's enough for tonight - we'll see how tomorrow goes.

I expect this thread may now split into two parts - the 'haves' and the 'have nots' - hopefully it won't get too complex and start to die. There is an important principle here that could see hundreds? of cars returned to the dealers as faulty?

and @slmorgan42 .

My dealer conversation today went like this:

"Its a paid upgrade."

(Lengthy discussion about why none of this was mentioned pre-sale)

How much is it? "Don't know". Well why don't we find out in case we're spending ages on the phone over a fiver? "OK"

Now waiting for a 'Master Technician' to call me and explain something to me. However, it seems plain that MG are just trying to squeeze the customer for a few more ££ not realising their goodwill is going down the pan.

Will update when I hear more.
They will probably quote £120-£140 for the update. I have a good relationship with my dealer (who I bought the car new from) and they threw it in for nothing along with the first service. I'm not sure that the dealer has to pay MG for the update but they do have to pay for the time it takes to do.

Hey

Yep you are correct the garage is just trying to cover the man hours.

My selling dealer has offered to charge me for 30 mins of work no matter how long it takes and how may updates they need to so. This seemed pragmatic of them. If I had known about the updates before my Nov service I would have asked them to do it then.

I am going to book it in even if MG is not covering it.

Never any harm in trying everything you can :)

Firmware updates are a tricky thing to price. If all goes well, there is 10 minutes of technician time to start it and check it at the end. Perhaps 5 minutes for checking along the way. Meantime, they can be doing other things, though I imagine it's a hassle trying to multitask like that. Also, the vehicle being updated might be blocking access to hoists or other equipment, and just generally be in the way.

But if it goes wrong, the technician may have to watch it most or all of the time, and it might take hours or even days to sort out dependencies that SAIC haven't foreseen. But presumably once they've done one or two, it usually takes way less time. But that's never guaranteed.

How do you charge fairly for such a situation?

Unless or until SAIC get Tesla-like over-the-air update technology. I wonder if that will ever happen. 🤔

Yep I agree with you about the dealers time.

I think the real point is why have MG not tagged this as a recall update. Then the dealers would be paid by MG and not us. MG have stated the car needs to be on the latest software updates to work correctly.

Mobile phones ,smart TVs etc provide free updates to fix vulnerabilities for a reasonable period of time . Yet you have to pay for such fixes on a £30 000 car? . Unethical or borderline illegal ?

Anyone else had these updates done and can confirm they can now charge using Tesla?

BMS, EVCC, VCU
 
I've looked at this thread often and still have no idea if I should expect to be able to charge from a tesla charger or not. I have a spring 2023 MG5 LR FL Trophy. I bought it from an MG dealer about 4 weeks ago. On Monday, I have the chance to try it at the open Tesla site in Harrogate, so will give it a go.

Is the opinion that I will be successful or not?
 
There is no easy way to know for sure. I am lucky and have a tesla charger near by so did a test and the answer was no for me.

As MG have not stated this is a recall the dealer will not know to do it unless you ask.

I have contacted my dealer to schedule in having the update done.

Straight answer to your question is it should but it may well not.

Your car is quite new so the only way to know is to try it but please do let us know how it goes when you try it good luck with it.

My guess is that it won't work. You bought it 4 weeks ago, but it was on a ship for weeks before that, and it might have been waiting for parts. They might program the ECUs in batches and leave them on a shelf until needed. All in all, the chances of each ECU being up to date enough for this is at a wild guess say 40%, so for all 4 to be up to date would be 0.4³ = 0.064. So you have about a 6% chance. That goes up to 16% if only 2 of the three mentioned ECUs is actually needed for Tesla charging.
 
Hi all. I have good news for Pre-Face Lift MG5.

Glyn Hopkin had my car in for service (2nd year). I advised of my issues charging in France at a motorway TotalEnergie site and that a 6 month newer MG5 charged with no issue at the same time, and that I'd also had charging issues with other chargers in the UK (GridServe, EVGreen (I think)), but didn't mention the 'T' word!
They were unable to update at the service (due to a system/download error) but it has since been back in and they updated the EVCC and, I think the VCU (although I'm waiting for them to confirm), FOC.

When it was in for the service I got a full copy of the 'VDSIII Diagnostic Report'. The EVCC software version was '1114351001'. The update has changed that now (again, waiting for confirmation of the actually version number) and I tested it on the Tesla chargers at Lakeside, Grays, last night.

I can confirm that the version now installed has allowed charging to work again.

If anyone was interested in seeing the full diagnostic report, let me know. It's got my VIN number all over it, so didn't want to post it here.

Regards,
Andrew Robinson

P.S. I had been able to charge with Tesla, prior to their restrictions, but not again until after this update.

Good to know there is an update to the prefacelift 5, although trying to convince the dealer to do it seems to be half the struggle.

They seemed blasé about doing the updates and said it was included under warranty. As mentioned this was going to be done at the same time as its annual service.

Seems to vary depending on which dealer you get, when mine was serviced in dec I was told it didn't need any updates.

I should plug the OBD2 dongle I have in at some point and see if I can get the current version numbers.

I am changing my MG5 SR on Monday for a new MG5 Trophy. I have specifically asked my dealer (Glyn Hopkin Chelmsford) to ensure it is Tesla compatible. At least, thanks to this forum, I know what to ask for! Wish me luck 🙏🤞

Be sure to let us know the result please! In fact, its pretty much on the way home so maybe I'll pop in and get yours - lol
 
Fantastic, and many thanks for that information Andrew.
And as pointed out by Dragons2611 it does appear some dealers are and some are not and making lots of excuses not to help their customers.
