Is anyone familiar with VAG parts, cooling connections are Normaquick NW12 which is not so easy to find.
Reverse image search of a Normaquick NW12 image
with something like "vag coolant connector" finds a bunch.
Straight,

110°? With little bleeder hose,
ACROPIX Engine Coolant Hose Connector Fit for Volkswagen Golf MK7 - Pack of 1 Black
https://a.co/d/eDVF2FE
There are a lot of options.
I'd suggest getting it from a reputable brand / reseller though. Use these to find the VW, Mercedes, etc. part number.
*Edit*
There's also this,

Just be aware there are smaller ones for heater hoses and might be a couple sizes for radiators / hoses.

Finally had a go at getting the charger running on Damien's code after getting myself a Due board. Code uploaded but I have faults with the locking mechanism along with communications fault on PT can. Could this block the 'Damien crude code' from running?

Ordered some 3B0122291B and sadly those was larger NW16. One from amazon with bleeder seemed to be physically much larger on pictures. So hunt continues

That's unfortunate.
I started a couple pages for cooling components.
https://openinverter.org/wiki/Coolant_Fittings
https://openinverter.org/wiki/Water_Pumps
https://openinverter.org/wiki/Coolant_Valves
As you dig for fittings, if you add info in the chart in the coolant fittings page it may help you and others work through this.

Back at poking the charger into life. In terms of coding, did you remove all options, even the type/brand of charger? The more I code options out, the more faults I get, but charger just sits there not charging.....

The issue I had was even with the lock coded out it still tried to lock and expected the correct feedback. If you just want a simple charger that works, I'd get an Outlander. If you want to carry on with the GTE charger, I'd maybe get a GTE charge port (lock) just to get past the locking feedback issue.

I'd really like to get this charger working. I have the vw charger port with lock etc. How did you get around the lock feedback issue without the charger port? The lock I have on the charger port has an electrical and mechanical fault in VCDS... I've taken it apart and ckeaned it. It locks then unlocks, but goes into fault mode. Since its outside of the donor vehicle, I have a doubt about faults. I have engine and hybrid CAN busses connected together as well.
Arduino code seems to change data (confirmed via Savvycan).

I didn't I just put it on my shelf and let it there. I since found out type1 to to type2 adaptor locking hole is too large so the pin is allowed to over protrude, this gives the wrong feedback value.

I managed to clear the lock faults. It locks when I plug in a type 2 granny cable. It then locks and unlocks when I connect the arduino board to run Damiens code..... sound familiar?

that's pretty much what mine did then didn't charge and had locking error.

FWIW Damien also tried to run the charger again on Discord briefly and it didn't work.

Thanks for the info. Maybe @Lrben or @Mitchy have a cocktail they think might work

I uncoded everything possible. I hooked up 12v to the HV side , but there's no change to actual values in VCDS. I'll keep to banging my head against the wall

Sorry I've been out of the convo for a while.
I haven't encountered the strange locking issue with the larger chargers, but you can try to add the gateway message, as there appears to be a 'vehicle locked signal' that is monitored by the charger:
0x644
you can just send all 00's for this message.
Likely the easiest way is if you have Savvycan setup, to just add the message to send via the canbus adapter; however if you like, you can try to modify Damien's script by adding the following just after the line containing the digital write (line 157):
Code: Select all
outframe.id = 0x644; // Addition of 0x644 Gateway Status
outframe.length = 8; //
outframe.extended = 0; //
outframe.rtr=1; //
outframe.data.bytes[0]=0x00;
outframe.data.bytes[1]=0x00;
outframe.data.bytes[2]=0x00;
outframe.data.bytes[3]=0x00;
outframe.data.bytes[4]=0x00;
outframe.data.bytes[5]=0x00;
outframe.data.bytes[6]=0x00;
outframe.data.bytes[7]=0x00;
Can0.sendFrame(outframe); //send on pt can
Not sure if this will actually work, but its worth a shot.
For the larger chargers, I sent the central locking statuses to mimic the car being unlocked, that seemed to clear whatever was causing the lock to latch in the locked state, afterwards the system would unlock the cable whenever a charge was ended.

Slightly off topic, but what is the message ID(s?) for the central locking status on the larger chargers? I took the lock off mine to get around that issue, but it would be nice to get it back on again.

Does anyone have a log that could run a charge sequence. Since Damiens sketch might not work ( and since I have it running on a Due board), I am looking for another log I could use. This would at the least validate that my pin set-up is correct. Another day of a charger looking at me....

yes, I tried the charge log. With my VCDS hooked up, I see that the charger sees the type 2 plug, ramps up HV to 315VDC and starts a duty cycle and then switches off. Plug temp is around 20 degrees, LEDs don't switch on. In the fault memory there are plenty "missing messages" codes etc, along with charger lock mecanism. it's not happy with some parameter , so a confirmed working log is my first goal so I can validate my bench setup. I'm going to try and get another charger plug assembly as the lock did have signs of humidity. The LED on the charger buttons don't work either,so I coded it out, but the faults keep returning (like Bigpie).

Another day of the "Damien Head-Wall Special). I've tried Dom's logs in differnt versions, but SavvyCan just shuts down each time I upload them. For now I'm playing Damiens 6A charge log back in Loop Mode and scrolling through VCDS Values. A couple of sreen shots showing diferent values, but the charger just sits there 'waiting'. I'll get a bigger heat element tomorrow as I took the iron element off when I looked at the specs tag (230VAC - 24VD!!).
But I still don't have another verifiable working log to run.

Couple more hours spent digging through CAN logs. Managed to activate a few values using VCDS to monitor.
ID-187 Byte_1_Bit_15_SET=IDE08649-IDE06971_Ready_to_charge_Operational_readiness_in_H-V_system-ACTIVE
ID-3A6_BYTE_5_BIT_40_SET-IDE08649_MAS07214_Ready_to_charge_Status_charge_readiness:engine-OPERATIONAL
ID-5EA_BYTE_3_BITS_25,26_SET,BIT_27-FUZZING-ENG126544_high_voltage_actiation_request-REQUESTED
The last one however is adifficult one for me. I have to toggle bit 24,25,or26 to get the Actual value to change, However I cannot maintain the REQUESTED value permenantly....some kind of rolling ID? Could it be linked to the famous Magic Bytes?
Hope this sheds somelight on going forward. If this info is somewhere else, please let me know so I don't go re-inventing the wheel.

I tried searching this thread but didn't find this. Are you spoofing signals from the BMS telling the charger it can accept a charge, how much, etc? It's where my head goes reading your ID-5EA struggles.

There's no thread for these findings, I've only started to document my findings now.
I've taken Damien's 6A charge log and sorted the log by IDs in descending order.
With my vcds hooked up, I selected what I think should be active for the charge process to work.
I ran the log through SavvyCan and saw a few values didn't change in vcds.
I then started taking rather big sections of ID's and "fuzzed" them.
When I saw one of the values changing, I broke down the logs untill I found the one that was related to the signal I saw on vcds.
I then compared this back to the 6A log and found that the ID was in it, so it must be related to running the charger.
So far I found 3 ID's. I forgot that some of the ID's are already cracked in the Arduino code that Damien wrote, so I need to go check that out and not reinvent the wheel, as there are quite a few ID's in that log.
Regarding ID 5EA, I can get the value to toggle, but never keep it happy in REQUEST state. I assume it does some kind of check and that there's other parameters that are required for it to remain in Request State.....
I hope that theres an ID or 2 that is needed to complete Damiens code (as it apparently doesn't work anymore). Then we can move on to polishing up a working solution...
