I thought it would be good to collect our charging issues and their solutions in a focused thread. I think it would be most useful to discuss vexing problems that are difficult to isolate here, and ones that cause specific errors (like Charging fault: “Only Emergency charging”) in other dedicated threads).

Thank you @Chuck and @heavyt for reporting your issues to VW. I have sent you a private message with my case number, and please include it when you correspond with VW to bolster the fact that many or all cars have this problem.
I think that we should all inform VW of all the open cases for this issue in order to inform them that this is a widespread problem. I'd be happy to include your numbers as well in my correspondence when you get them.

The owner's manual explicitly says "Avoid regular rapid charging with direct current (DC) due to the high charging current" so we have been warned.
That said, I have not heard of leasees ever being dinged for this.
I tried a different experiment last night. I configured only to have preferential charging between 11:55PM and 3AM, but not scheduled charging. When I first plugged in, it wasn't drawing any power from the EVSE, which seemed normal enough. Starting SOC was about 50% or thereabouts, and charge limit was 80%.
This morning, I found the car at 75% SOC, and the JuiceBox showed this data:
![3178]( "3178")
What was interesting was that it didn't start charging right at 11:55. It was almost an hour later when charging began, and it was going more or less right at full speed. But there was about a half hour where the power dropped to around 6kW. Can't explain that. But it did stop charging at around 3AM.
There were still momentary power glitches - drops to 0 every so often for reasons that are unclear.
It sort of seemed like the car was trying to anticipate how much charging would be needed to bring it to 80%, and delaying the onset of charging. But when it did charge, it was mostly going at full speed.

Thanks for doing and reporting another useful test. Looks like your results are similar to the ones that @Sita8 got in post #31 in this thread for a similar situation - charging started by did not achieve the set SOC. Your Juicebox data are great and I encourage you to send them to VW at VWCustomerCARE@vw.com with reports of your problems.
I established a case with VW on this general problem and they had me take it in to the dealer's service department about 10 days ago. Further testing showed that the dealer's "software reconfiguration" (per the invoice) did not fix or change the problem. VW has asked me to take it in again and I'll report back after that.
I am having same problem. Case No. is 04732715

Perhaps - it helps a lot when you want a "second set of eyes" on the charging process, that's for sure.. But I gather that many models of EVSE are back-ordered at the moment.
I expect that this is a temporary situation until VW pushes out an update to correct this.
That's definitely the case. I couldn't find a single one that I would trust, though my list is basically juicebox, CC, and grizzl-e so that doesn't help. i ended up getting a grizzl-e because i don't have variable rates anyway, but i would have loved to get their upcoming smart version. I'm not touching anything that's not coming with a UL cert.
I'm looking into switching to a different TOU electric rate plan. My current one is designed for EVs and has lowest rates midnight - 3 am (Nor California PG&E EV2). I can change to one that has low rates from 9pm - 4am instead (TOU-C), but its low off-peak rates are considerably more than my current EV2 plan. However, this will be offset some by getting paid more for any excess solar power I generate.
Is VW’s response to this indicative of total ignorance to the ID4’s numerous bugs? They really never noticed this in their own fleet of testing?
This makes me worried that many of the bugs we experience on our cars won’t be fixed for a long, long time. Instructing us to go to the dealer to have the same software reloaded is just a waste of time.

I assume and hope that the VW engineering team is indeed aware of the problem given that it is so obvious and widespread. My case manager claims to not know of any other similar issues, and I think / hope that is because the VW ticket system is too cumbersome with the customer care managers disconnected from the tech team. Having the dealers in the loop for diagnosing software problems like these only makes the chain less efficient in my opinion, but that is their current process.
Thanks again to all for reporting your cases. I'll relay the numbers to my regional case manager when we speak on Wednesday. Hopefully having a significant number of cases logged will raise the priority of fixing this particular problem. Lots of hope here.

Fortunately then that we'll be getting firmware updates originating from big VW and not VWoA. 
I don't have off-hour rates so the scheduling flaw hasn't been an issue. I just plug in before going to bed (I still think it's best to go off-hour, so as not to add to local utility daytime surge). But I do appreciate that those with such a plan are missing out on savings and hope it is rectified especially for them soon.

I have a TOU plan, but we live 11 minutes from an EA station and don't drive a whole lot most of the time, so we're just planning to do EA charging once every few weeks whenever it gets down to <10% SOC. Can't pass up on that free charging!Fortunately then that we'll be getting firmware updates originating from big VW and not VWoA.

An EA station is being built near our home as well, so if I can't get my cheap nighttime charging working, I think I'll do the same!
I'm happy to hear that the EA DCFCs are good alternatives for some people while the delayed charging issue gets sorted out.
I bought my car instead of leasing, and I'd like to restrict DC fast charging to infrequent usage like road trips. I saw the battery in my last car degrade ~5% after about 10 DC fast charges at about 1C rate. That car did have a good thermal management system but older battery technology, and hopefully our ID.4s will do better. I also like the convenience of charging at home too - when it aligns with low power costs.
