Re: Error: Electrical System. Stop!

You're right, I saw 100K listed online as well and called the dealer and they confirmed, thanks! The service consultant gave me the incorrect 80K mile warranty figure. I don't have any diagnostic hardware but the service consultant said 1 of the 27 battery pack modules that make up the battery was r...

Re: Error: Electrical System. Stop!

Really too bad about all of this, love the car but it seems like VW isn't quite ready to handle maintaining their electric vehicles, at least not this model. And I'm seeing now that maintenance cost savings are much less of a guarantee. Here's the story: My 2015 eGolf with 79K miles had an "Electric...

Re: unable to start remove charging plug. Works after a minute.

The same thing happened with my 2015 and ultimately VW replaced the charging port on the car. The solenoid that retracts the locking pin would occasionally not retract but luckily I could push the pin back using a screwdriver. This work-around was fine for a couple of months but eventually the solen...

Re: Dealer needs our help determining usable capacity

Found it, http://www.myvwegolf.com/forum/viewtopic.php?f=12&t=564 The key parts: On page 26 of 60, under "Battery Monitoring measured values", these two numbers pop up: Param_SOHP 89% "SOHP" means "State of Health Power" If it helps track things down, the section actually looks like this: Function c...

Dealer needs our help determining usable capacity

Hi all, I'm sitting at my local VW shop waiting for my 30K mile service to complete, and asked the dealer to provide the current usable capacity for the battery: the service rep hasn't heard of such a thing. The service rep at my 20K mile service also could not provide this figure. About a year ago ...

Re: Which EVSE to buy??

Very well said, I read your hackaday write-up on the hydra and the blown resistor situation, what a pain. That is a great point about reviews too, it would be great to see a charging system reviewed just like we get when they review a navigation system. Next time I see an EV review that interests me...

Re: Which EVSE to buy??

Yes it sure is strange but when the eGolf's charging system is in its sleep or off state, it isn't following the J1772 specification anyway, so we don't really know what it thinks about the -12V to +12V transitions. Once that amber light next to the plug illuminates it will at least begin the chargi...

Re: eGolf and EVSE pilot sequencing - problem

I'm currently using an OpenEVSE and had to perform a code change in order for it to "wake up" the charging system on a 2015 eGolf. I describe the necessary code change in this thread http://www.myvwegolf.com/forum/viewtopic.php?f=12&t=148 I'm trying to reply to all the threads I see about this issue...

Re: JuiceBox Green

I have an OpenEVSE so am able to modify the source code of the unit, and found that you can toggle the pilot pin from -12V to +12 two times, with a 1 second delay between each transition, in order to "wake up" the charging system on the 2015 eGolf. I tried different delays and different toggling seq...
