Parasitic drain on 12V battery

Join the club. Mine is being replaced on the 30th

Common pattern forming here me thinks .
Sounds like they have had a bad batch of faulty T boxes to me !.
Which does confirm that even new cars can have parts failures then .

When a parts buyer doesn't read the fine print on the great price they managed to source a required item ..... small details like QC 1/1000 rather than 1/100. If 1 unit is tested in every batch of 1000 and it comes up to be within spec, that is taking quite a gamble that the other 999 are also be within spec .... check 10 units out of each batch of 1,000 and they all meet specs, there is fair level of confidence that batch will be mostly good

And here it is...!

MG Technical have decided the car needs the T-Box replacing!

My S5 is currently in for investigation, nothing yet heard after 3 days!

Don't panic; it took more than a week of diagnostics for MG to finally admit the need to make this change!

I'm collecting my New MGS5 in a couple of weeks should I ask my dealer about this?
What is a T box ?

 

[JohnV6]

It handle the connectivity to the web etc. When it fails the SOS call fails as does thesat nav, mg app etc

This is normal for MG at least.
It’s a long winded process.
They have to be authorised by MG CS to carry out their investigations, or they run the risk of not getting paid for the time.
If they need help in diagnosing the issue, they have to raise a ticket and then upload there findings of the tests they have been authorised to make.
Then wait for a responce and further instructions.
If the car needs any parts ordering, it has to be granted by them.
All this back wards and forwards takes time unfortunately and this is what makes the process so frustrating for both the dealer and especially the customer.
This way MG are in total control of the costs of any labour and parts.
It’s a similar system with other manufacturers, but the time taken is much slicker.
Of course wait times on spare parts can be lengthy, IF they are not held in the U.K. and therefore require shipping from China.
MG has said that they do intend to improve parts supply to the U.K.

I've got my S5 back, the ONLY abnormal recorded drain was from my permanent live Viofo dash cam!

I'd inadvertently disconnected the rear camera instead of the permanent live feed, so it appears to be my fault, ok hands up if it's my mistake, I'll put it down to senility.
I hope they are correct, but what I don't understand is why the battery drain only happened in the week or so leading up to Christmas, I fitted the dash cam mid September.
I can only wait and see, but I'm not 100% confident the temporary removal of the dash cam will be a permanent fix to the battery drain.
If it does turn out to be the dash cam, I'll rewire the feed to switch from a different ignition switched fuse.

One thing this saga has taught me is that when we eventually replace my wife's Hyundai Tucson, it won't be similar to the courtesy car I ran around with for 3 days, a new 75 plate Peugeot 208 EV, in comparison, the S5 is very composed, much nicer to drive, the range on the 208 is rubbish, very jittery, even bouncy on the road.

Interestingly on lengthy MG parts delivery times @Lovemyev , I recently ordered some unimportant S5 under centre armrest storage trays from China, (thanks @Ian Key ) less than £15 value, they arrived by DHL airmail 7 days from ordering, so why do spare parts take weeks and sometimes months to be shipped to Europe?
Sounds like a possible supply chain delay, but I can't imagine why, it's mysterious.

It could be that the pieces from AliExpress were already sat in a warehouse just waiting for an address label to be attached to them. The parts from MG would have to be sourced from the parts supplier, checked, packed and shipped from China.

They couldn't be taken from the production line as they will be operating a Just In Time system where everything is counted as it's used and automatically reordered.

Given the distance, it is likely that parts are not shipped by demand daily either tbh.
If the parts are coming from China then they maybe sending only once a week, once every two weeks or even once a month !.
There is likely to be a “cut off point” also, if you just missed the “cut off” then your wait time is increased.
When parts where ordered for our previous ZS EV Gen2 the guy in the parts department told me, that after they have been authorised to place the order, it will take a few days before the status updates.
If it is shown as “back order” then it’s coming from China.
But you have to rely on somebody to keep checking on its progress status.
When it updates, the system will predict an estimated ETA.
Again, this needs to be monitored.
Usually the dealer will then get a message / e.mail when the items are going to arrive with them.
We required two items for our car and both ordered on the same day.
One part arrived out of the blue after two weeks, but the second item was delayed another week and then finally arrived.
So this MAY suggest it’s weekly delivery ?.
Maybe held up in customs ?.
As soon as the second part arrived MG CS called the dealer and told them to install the parts that day !.
Because they had informed the hire company to pick up the car from my house on the very same day and they did !.
Total wait time from delivering the car to the dealer by recovery service, to back on our drive fixed.
Three days short of one month.
The two parts cost less than £200 and about two hours of labour to install.
Cost of the hire car - unknown but expensive I would expect !.
I am 100% sure this is what was driving the speed of the repair by MG CS.
It’s purely not cost effective for all parties concerned and if MG did not see this coming, then they have been totally naive .
