19.2kW charger fix for EA charging and Plug & Charge

[kort]

There is also a digital certificate issue with some chargers (related to securing and authenticating your VIN with the charger to verify you are authorized for P & C). The good news is that these are all software issues, and VW Group controls EA and Porsche. So things can be fixed. It may just be a matter of them not being fixed fast enough for any particular owner or their particular travel plans. Welcome beta testers!

Things can be fixed doesn’t cut it when you are at a charger and cannot charge.

Very true. Didn't mean to minimize the pain and frustration those affected have encountered.

Hopefully with this new patch my ownership experience will improve

Doesn''t that comment sort of universally apply to most Taycan issues?

I can overlook the minor issues like wonky car play or other issues like I had, the car was reporting bad turn signals for a couple of days but big ones like the charging or the battery fails aren’t tolerable

I hope you will agree, the fact that on more than one occasion at least 4 PCNA employees spent their weekends driving around to various Walmart parking lots says something about their commitment to Taycan owners. It took them little more than a month to turn around this critical fix, which is impressive any way you slice it. As a result, I've gone from the edge to a very happy and impressed customer.

There are customers out there who are willing to help debug issues with detailed repros and sometimes even more. Unfortunately not all manufacturers listen. Once, when Tesla had slow MCU 1 responsiveness, some customers noticed that turning off real-time traffic overlay solved the problem, one customer dug even deeper, rooting their system an reverse engineering it to figure out that for some reason the traffic update was being polled every 120ms instead of every 120 seconds - sadly, Tesla still ignored that for many months. :-(

What would impress me even more if manufacturers would open more technical documentation to customers, so that we don't have to resort to reverse engineering in order to debug our cars.

@whitex I agree that more openness and community involvement as you see in other technical industries would be hugely impactful for customer sat, and I have shared that sentiment with people at both Tesla and Porsche. There are certainly industry & organizational cultural issues at play, but I have also heard from individuals who would love to be more active on forums, etc., and they simply cannot due to government regulation like the TREAD act which requires formal communication and process around anything related to vehicle defects like the one we are discussing here.

Speaking of, I have heard that this fix is moving along quickly and a formal bulletin should be pushed to dealers within the next week or two!

My normal service advisor is out for the week, but his associate got back to me:

"I checked your vin number for recalls and campaigns, and it looks like this was performed last visit.

The attached screen shot is the campaign number as well as what issue was being taken care of, which is specifically for a software error in the 19.2 kW on-board charger."

What he provided was the WMG4 update. So, as I feared, without a campaign ID it is going to be next to impossible to get the software update related to this EA issue. Mentioning reaching out to "PCNA tech" isn't going to work.

Forgive my ignorance, but how is the TREAD act getting in the way of users debugging issues like this?

This tread got my hopes up. I have to borrow my wife's phone to charge her 4S w/19.2 kw at our local EA charger (Porsche has not been able to figure out how to have two phones authorized to charge her car). Scheduled a software update, explained details shared in this thread, software update done on Tuesday, tried plug and charge last night, failed. Back to square one.

Since we have no real reference number for the update, can you verify what update was applied? Did the service advisor understand the request and apply this "custom" fix? What does the paperwork show from the service? Just curious as I "was" excited about this fix as well.

If they applied campaign WMG4, as they did to my Taycan in mid-August, it does not fix the issue.

Personally I'm not even going to try to have this conversation with my dealer until there is a specific campaign associated with it.

This sounds exactly like the power loss software fix. There was a period of a couple of months that Porsche had the fix without a campaign number and it would apply it only to cars that had experienced the issue. If you asked your SA if there is any pending software update, they would see nothing. But if the car was checked in because of the actual problem, then the technician (not the Service Advisor) could find the new version in their internal technical knowledge database while searching for "power loss".

It is probably no different for this 19kw fix. The SA will not see any update until it is officially released with a campaign number. But if the car is checked in with the customer complaining that the DC charging fails, then the technician will find the yet-not-officially-released software in their internal knowledge database. So if you want this update very badly, book an appointment and really complain that your car cannot DC fast charge at Electrify America.

Wise man. I tried briefly and they ignored me, more or less. If it doesn’t show up as a campaign when they run the VIN it doesn’t exist.

It appears the only update that was applied is: WMG4. As stated many times before, this update does not address the issues. Just sent a message to the SA and asked him to work with the tech and dig deeper.
