Tesla Supercharger Issue MG5 LR

[MickeySw]

Unless there is an evolutionary upgrade to EV tech in the meantime ?‍

It’s already on the horizon: if the promised advantages of solid state batteries turn out to be true and EVs equipped with them become widely available, few will invest in a second hand ‘old technology’ car and then only at rock bottom prices…

I think it was Jimmy Watt told me that too once.

Out of interest, how many pre-facelift MG5's were sold? Anyone know?

As I see it, due to MG's total lack of interest in doing the decent thing with this, how many future sales are they risking with the 'tough luck, we don't care' attitude?

I've praised MG to the high heavens all over the internet and find myself in the position that I wouldn't recommend them over this issue...

Shame we have so little leverage over a minor update...

 

[kevin ellard]

You probably need to re-read a few more recent posts things seem to have changed from MGs perspective. You might also want to watch the podcast where Miles and Les talk it through (from about 58 minutes in)

I don't really have a dog in this fight anymore as my FL was done by my dealer and I'm very happy with the result but....
I fail to see how MG can say that fixing a bug in the charging procedure could be a warrantee issue for one car but not for another. It is either a problem that needs fixing or an "improvement" it can't be both depending on how much it might cost to do.

from How Many Left?

These are MG5s pre FL registered in UK by model and year. Figures available for the FL too but not included here as they get the update anyway. Unfortunately no breakdown by battery SR/LR.

MG5 Excite
2020 - 70
2021 - 1334
2022 - 1665
2023 - 52

Total - 3121

Exclusive
2020 - 204
2021 - 3739
2022 - 4787
2023 - 61

Total - 8791

Total of all MG5s - 11,842

HOWEVER when looking at the combined total for the MG5 family on the site there is a discrepancy as this shows for 2023 that there were a total of 1696 new registrations therefore giving a total for all of 13,976

Is it possible to argue the inablity to charge on Tesla chargers is a product defect given both supposedly support the CCS standard.

Worth a try , I suppose . Don't think it'll get anywhere though . Probably better to publicise the limitation of MG charging options . Loss of potential sales would concern them MG more methinks

We would need a group actions to make it viable and an expert witness.

The problem is that the charging standards are widely open to interpretation. This used to be the case with the type 2 where I could design a type 2 charger that would work with all the local chargers near me but failed in Brighton for example which had different charger hardware that behaved differently. The reason was a difference in interpretation causing my system to recognise the "normal" operation as a fault because it was not in the standard. Once recognised, easy software fix until next different unit was encountered.

A common problem would be load balancing where the charger would reduce the current available but the car would see that as a fault and stop charging. One home charger has the habit of doing this by disconnecting the mains first and then restarting to load balance. Car sees an "emergency shutdown" and sulks. Whose fault is that?

By and large those problems have been ironed out but the CCS standard is again open to interpretation which is why some car/charger combinations are iffy. CCS also uses comms over powerline communications which can be a bit iffy as well. Sometimes it is due to additional protocols that have been added. Some times, it is timing issues that expect something to happen within a certain time period.

It would be pretty hard to argue that Tesla implements the true CCS standard and nothing else. It implements a TESLA version that incorporates it which is not the same. MG argue that it is an upgrade because of that as their cars work with normal CCS chargers. There was no requirement to work with Tesla Chargers at the time the systems were developed as they were proprietary. If other charger companies were offering the same lower pricing, would there be such a need to get a Tesla fix?

Equally I hate to think how much work was involved in the upgrade and testing it. Maybe it is not surprising that there is a charge for it. £72 can be recovered quite quickly with the ability to use cheaper Tesla chargers.

The latest from MG seems to be the PFL needs an entire new CCU at £800+ dispite some people already getting it fixed with a software update.

As to how a big a problem not being able to use Tesla chargers becomes it will largely depend on which other CPO's use Tesla V4 hardware and if the V4 hardware running in whatever configs the other CPO's use has the same issues.

 

[JimD]

I recall the reason some MGs can't use Tesla chargers is because Tesla deliberately blocked them as they were bricking the chargers.

Did Tesla make a deliberate choice to do that rather than change their own software to accommodate different vehicles' implementation for commercial reasons?? Makes you wonder.

 

[dragon2611]

I never know when I get an issue with public chargers if it's the car or the chargers fault, or most likely a bit of both.

As I understand it the only PFL cars that need a new CCU are those SR versions. It appears that the LR PFL can have a software upgrade. My PFL LR is booked in for the upgrade in 10 days time. We shall see.

 

[dragon2611]

There seems to be conflicting information about that, some dealers are saying any PFL needs a new CCU.

Why would Tesla intentionally block all MG's?

Not sure, but the Tesla SC network is probably one of the biggest selling points for buying a Tesla. Considering their SC network and everything else you get, the new Tesla Model 3 is beginning to look like good value for money.

I wonder if that will still be the case now they've fired the supercharging team, not sure who's looking after it at the moment.

 

[Coulomb]

now they've fired the supercharging team,

The maintenance people were never fired, at least not en masse. The supercharger locations will keep expanding, just at a lower pace.

 

[maskull]

Thing is , imagine buying an ICE car and being told you could only to use Texaco fuel . Extreme example I know ..but

They didn't intentionally block all MGs. They blocked cars that had a fault that was causing a problem. It just so happens that the MG5 was one of the cars that had the fault. I don't think that anyone with an MG4 ever had a problem with superchargers.

It used to happen: the Rover 3500 needed high octane 5 star fuel to run which only a couple or petrol companies supplied.
