Surely if it is so important to do this BMS update MG should be recalling all relevant cars for a compulsory update using the comprehensive information they hold for our service history online documents - If they know where they are kept.
If only it was this simple ( and it should be ) as this stage.
It is my understanding that ALL dealers have access to the SAME service bulletins at every branch.
So, they should be all following the direct instruction laid down by the manufacture.
As WE don’t have direct access to these updates, we can not see directly how they are worded.
Are they instructed to apply these updates only if the car develops a fault ?.
The BMS software update is a strange one alright.
Some cars get it, some cars don’t ?.
New cars arriving here now, I am assured WILL be running on the latest 450 volt BMS software package.
Any new stock vehicles that have been sitting around for a while unregistered, will be running on the older software.
Should these cars be update as part of the PDI inspection, of course they should.
All cars should be standardised.
But will all know how basic a PDI service can be.
Plates / Polish / Ship.
I agree it can become a bit of an issue, if the dealer advises that the BMS update should be done, but the customer actually refuses it, this could have warranty claim implications in the future.
Let’s just say as example here, your car has developed a fault after about two years and you had not submitted the car for its annual service.
You now require a warranty claim that will cover the parts and the labour costs.
Are you likely to have that claim satisfied because you have skipped the correct process laid in the T&C’s by the
Manufacture?.
Quick answer - NO !.
One of the major selling factors of getting your car serviced at the main agents, is this.
And he or she writes.
“Your car will receive ALL of the latest and necessary safety updates recommended by MG to keep your car running in the best possible running and safe condition”.
And yet still some dealers are clearly not carrying out the direct instruction from MG with regards to applying this updates - Why ????.
There will be an official MG book time given to the dealership to update these cars.
The dealer will be able to claim back these hours back from MG.
However, if the update takes longer than the book time, or the upgrade is applied incorrectly, causing an issue with the car.
Then the dealer will be standing the cost of the labour from this point onwards.
Does this go someway to explain WHY some of these updates just don’t get done then ?.
Manufactures do NOT like recalling cars, they will avoid it like the plague.
It reflects badly against the brand.
They prefer to call them “Produce Enhancements or Improvements that can be carried out at the customer’s convenience”.
Or some other close B/S term of phrase.
My previous VW PHEV had no updates applied at its PDI check, but at the first service it had 13 updates down at the same time.
Every module in the car received some type of update.
Did I request it - NO.
Did I get the chance to choose if I wanted it or not - NO.
I was the largest volume that the senior tech had ever applied to a car in one session.
The car was booked in for a small service and ended up spending the whole day hooked up to the computer and it was not ready for collection until the following diner time.
Massive update, but no problems when I received the car back !.
