You can "interpret" the standard and actually signal below 6 A but it then depends on how the onboard charger unit is set up to respond. A further complication is how accurate does the waveform and the measurement have to be and what happens if it is on the border? Is it 5 or 6? The...

I have had a reply back from Customer service - aftersales. Vague statement that we already know! I have it on good authority that I am right and that the EVCC does not need changing and that the bulletin should be changed to include an EVCC check to confirm its compatibility before applying...

This is one of the compatibility standard "holes". There are two operational factors that determine the charging current: the cable which is identified by a resistance that states the maximum current the cable can support and signals from the "charger" that indicates the maximum current it can...

You didn't but many others have as this is an oldie but goldie picture. Just wanted to make sure that people understood that the Outlander issue was a Chademo one and nothing to do with the CCS fault that affected MGs which I am pretty sure is a charger issue.

DRive your car for a bit and they will vanish as the car sorts itself out.

If it any consolation - and I know it is not really - even the cars from yesteryear had software issues: the Vauxhall Cavalier SRi had a feature in its ECU that said if the fuel pressure was dropping, make the pump work harder/longer. It didn't know that the driver (me) had run out of fuel...

It is a nightmare for you but as someone who has been on the other side of the fence, i.e. having to write the software and then test it , it is a nightmare for the manufacturer. These systems only work because of the standards that define how they should interoperate but that does not stop...

I would try charging from a non PV source just to remove that from the equation.

Not so sure about it being an MG problem... Seen this a couple of years ago on a Zappi install where the Zappi unit would disconnect the mains instead of using the charging protocol to pause or adjust the judging rate. Naughty Zappi as this is not how you are supposed to do it. Never saw it...

The Outlander doesn't have CCS and the issues were when the cars were plugged into Chadomo and it was reported that is was caused by errors in how the charger adjusted the DC voltage. Nothing to do with CCS at all. The MG problem is believed to be similar to that introduced into the Tesla...

Having gone through all the ads on Ebay for the EVCC, and collating the build dates etc I am confident that: The unit that is in the MG5 LR is an EVCC-02 which is the same unit as fitted to the FL cars and MG4s! There are at least five different part numbers assigned to these units but the...

Just been speaking to MG customer service who told me that I had to go back to my dealer... I then explained that I had spent over an hour going through this and had seen the MG bulletin that said change the EVCC to the same version that the FL cars use. I then said that I had that already as...

Except the manufacturing date would preclude a 2020 excite which would be a SR car. I did do some further checking and found this which came from a facelift owner. The reference numbers are the same. The LS car is definitely PFL but the other one is from a FL car. The read out below shows that...

EVCC from a pre and post facelift car! Exactly the same!

That is the conclusion I have come to: the LR EVCC is the same as that fitted to the FL cars with a slightly earlier MG software release. I have got data that indicates that they are the same. The first ref is the base software revision that MG receives from the supplier. The second number...

Thanks for that. Unfortunately that is the charger and not the EVCC which is a comunication controller which I think is part of the charging port assembly but don't quote me on that. Still digging but it does look like the PFL LR cars have the same EVCC as the face lift cars. Still digging and...

It's basically an OBD2 scan which identifies the ecus in the car and revision information. It would be really useful if your dealer could do a before and after scan of the ECUs so that we can see what the difference actually is. It also means that we have a definitive if you have this revision...

Just got back from a service and tesla update that did not happen.... Well it seems that all PFL MG5s need a charger swap or to be more accurate all mk1MG5s need the new charger at a cost of £500. This makes a mockery of the fact that LR PFL cars have had the software upgrade applied and work...

For the £72 quid charge it is worth a try. If it doesn't work then I do most of my charging at home and it is not that big a problem as you say. Anyway it gets done on Wednesday. Fingers crossed!

Thanks for that. Appreciated. Interestingly so we have a timeout that occurs with Tesla and MG but not with other chargers and MG. That does throw the suspicion back on Tesla doing some non-standard stuff. It may be a symptom of what happens but the cause is not necessarily anything to do with...
