Only they can answer that for definite, but from mine and others experience of the service from Chorley Group MG, it will.I collect my zs from Chorley on 1st March, will it have all updates, including EVCC and BMS?

I would guess they will mine included all updated updates at time of collectionI collect my zs from Chorley on 1st March, will it have all updates, including EVCC and BMS?
Isn’t that called a “recall” lolSounds like MG are trying to prioritise the car’s ( from a VIN list ) that they KNOW have received the “Buggy” software first.
The sooner these cars are updated, the less likely the HV pack will be affected by the “Bug”.
Car’s still running on the factory software with NO BMS problems, will be updated as a mater of course at a later service date I think.
The car’s that are badly affected, are rightfully being given urgent attention by the dealers.
Who can ever be certain regarding this! I’d say it’s 99% likely all cars will be updated when they’re in for their service. What software level exactly as we know will be hit and miss!Good summary. Are we sure that all cars running the 455v BMS will get mandatory MG updates to move to the 450v one? I might have missed this - I know that those without issues are not a priority but I’m unclear if the 450v BMS update is going to be applied as a mandatory update across the board on all cars even if they’re without issues.
If you do that please let us know the result.Just for context I had a BMS update November last year which I believe is the buggy one, 444 Volts after 7KW home charge to 100% and several hours of balancing - range showing 147 in normal. I spoke with my dealer this morning who told me I did not receive the buggy version. I told him the figures above and he told me to run the battery down to empty and then slow charge on the 7KW to see if that rectifies the problem.
Picked up the car on the 3rd Nov. I only had a problem with the navigation system. After 3 weeks of speaking with the dealer who always assured me that they would call me back and never did. Today I rang and after 30 minutes got a call back from the service department and was informed that I have the bad BMS. Booked in on the 15th for that, nav system and charging unlocked on AC. Not really noticed it as bad as others, but only done 900 miles in 4 months.Just for context I had a BMS update November last year which I believe is the buggy one, 444 Volts after 7KW home charge to 100% and several hours of balancing - range showing 147 in normal.

This continues to rumble on with varieties of advice and levels of dealer support. In your case 147miles range looks good but voltage looks low for a full charge. My understanding is that you do not need to run down low your battery to equalise the cells. Just take it down to 95% or below and then charge and let it equalise. There’s loads on here as you probably know on this topic. I would certainly consider ask your dealer for the latest January 2021 update if you’re concerned.Just for context I had a BMS update November last year which I believe is the buggy one, 444 Volts after 7KW home charge to 100% and several hours of balancing - range showing 147 in normal.

I got mine from Chorley Burnley last week, I was told all the updates had been done, but it looks like that's not the case. My voltage after a full charge is showing 457v and it's doing a long equalisation after each charge. I believe it should be 450v if the latest BMS update had been done. I'll be speaking to them soon to find out what's going on.I collect my zs from Chorley on 1st March, will it have all updates, including EVCC and BMS?
Wow I thought Chorley were the one dealer that knew what they were doing.I got mine from Chorley Burnley last week, I was told all the updates had been done, but it looks like that's not the case.

Chorley have been great with everything, I've not been in touch about this yet. They definitely gave me the impression that they would sort anything out if needed.Wow I thought Chorley were the one dealer that knew what they were doing.
You have run it down a bit and recharged since getting it? I'm saying that maybe incase it was charged to 455v and then they did the update, so it's not been "cycled"?
Hmm, weird it went to 450v the first time.Chorley have been great with everything, I've not been in touch about this yet. They definitely gave me the impression that they would sort anything out if needed.
We ran it down to about 35% charge, then charged it at home, it took a long time to equalise and I put this down to being the first full charge, afterwards the voltage was 450v.
We then did some more miles. I have a long trip coming up I put it on charge to get back to 100% from about 80%. Again it took a long time to equalise but the voltage was 457v when completed.
Because of the voltage being 457v, I ran the battery down to 90% by collecting children etc.. and topped the battery back up, again a long equalisation, it's about 3 hours so far and still going. The voltage is back to 457v.
This is making me think the car doesn't have the Jan 2021 BMS but one from summer(?) 2020.
Miles R has stated that ZS EV models leaving the factory will have the latest BMS update that displays a voltage of 448 - 450 volts after a full charge / balance.Good summary. Are we sure that all cars running the 455v BMS will get mandatory MG updates to move to the 450v one? I might have missed this - I know that those without issues are not a priority but I’m unclear if the 450v BMS update is going to be applied as a mandatory update across the board on all cars even if they’re without issues.
