Hi All,
As this thread is still ongoing I just wanted to check that EVERYONE reading this has already raised a Service Appointment request for these issues with Tesla already? Can you Like this post if you have done it?
The only way they are going to prioritise getting this fixed is seeing lots of support tickets raised. Here is some text again to copy and paste into your request. It will take you 30seconds and make a big difference!
"I am raising a service request as my car is not operating as designed:
1. Car does not wake from sleep when offered charge
2. When using scheduled charge car always charges at 16A even though offered 32A
3. During charging car does not automatically accept the maximum charge rate (Amps) when the charger varies this over time."
Also I kept having issue number 2 and it happens on the nights I need the charging the most. I have therefore written a NodeRed workflow on my Raspberry Pi that checks the charge rate of the charger (OpenEVSE so has local API but you could use the Tesla API too) at 00:35 and if its <17Amps it disables the charger for 30seconds and enables it again which seems to clear the issue and charge at Max. If anyone wants a copy to play with I am happy to share.
@Jeremy Harris Did you get any further with your experiments on the pilot line and trying to simulate the UMC? I wonder if faking that the charging cable has been unplugged would wake up the car? Did you manage to intercept what the UMC was sending on the Pilot?
Thanks All!
Hi All - quick update on this.
Its been 9months since I owned by M3 and nearly 3 years since they started production and still this defect where EVSE cannot wake vehicle to charge has not been fixed via software update.
I suspect if it could be fixed via software then it would have been by now meaning the engineers probably found that the hardware cannot support it and therefore would require a recall if they admitted it.
My M3 went in for a service to fix some paintwork last week and this charging issue was still reported on my file from when I raised it last year. They gave the same explanation that this 'feature' will be enabled through software update in the future. However I refused to pickup my vehicle until they gave me a date for this being fixed and reminded them it is not compliant and a fix not a feature.
They have since escalated with the central engineering team who contacted me today asking for timestamps of when this happened. I did a set of tests for them today proving that it still doesnt work and that its not the charger. They are looking at the logs and will get back to me.
I have also raised this as an official complaint with the customer services team as part of a 2 pronged attack.
Will let you know when I hear more...
Incidentally the Model S and X i have been given as courtesy cars both woke up no issue from my charger from sleep.
If anyone reading this thread is still frustrated and cares about getting this resolved please can you raise a service appointment through the App - it will take 30seconds and just paste this in...
"My vehicle is not able to wake from sleep by my EVSE charger meaning that it is not compliant with the charging standard and I cannot charge when there is excess solar or dynamic variable cost tariffs. Please provide a date when this will be fixed"
The date and location for the service doesn't matter as they will cancel it anyway but at least it gets logged as an incident of the same cause. You can post any replies you receive on here.
THANK YOU!
@Jeremy Harris - did you ever get any further simulating the digital comms of the UMC?
