Ah. Found it. Golf/Jetta have slightly different wiring to the trunk popper. That's an easy fix. I'm sure the new coding will work fine after I get that sorted.

If you currently have an IMMO2 cluster, you should be able to install an IMMO3 cluster as they are backwards compatible.
Funny you should say that, because I've had this 8L Audi S3 cluster —with adapter cable I built — sitting in a box for (checks notes) seventeen years waiting for Greg's incredible work here! But I have a feeling it'll be near-impossible to find any documentation of the addresses I'll need to modify in that particular cluster.

Have you looked to see if this will support your needs?

While playing around with the hatch solenoid one time, I found that switching wire positions reversed the behaviour of the solenoid.
maybe that does something for you. 🤷‍♂️

Can anyone confirm for me, does the remote window operation also open/close the sunroof, like key-in-door does?

So here's my cluster part (without actually taking it out):



And then when I run kw1281test.exe, I get this. Also, this is a 2000 Beetle TDI. Wanted the SKC to swap clusters, because I'm trying to trace down a problem.

"Unexpected sync byte" usually means you're using the wrong baud rate. I think Beetle clusters are always 9600.

Looks like I broke something in version 0.72 (I did a lot of internal reorganization). Try version 0.71 for now.

Will do. I'll report back shortly, before I give up on this car; Here, I've been so spoiled with easy to work with VDO clusters...

YAY! Thanks Greg!

Awesome, will do. Is there a reference chart somewhere for noteworthy 1J0 addresses? I reread this entire post history today in search of a relevant reference, and had no luck. See attached for the items I'm interested in modifying.
So I've been meaning to make a post about this, just haven't gotten around to it. Joined the forum just to post about this.

Cool mod I found from playing around with the CCM binary is the center red circle byte #3, bit(?) #4 - currently labeled "turn on rear wiper when hatch unlocked*" actually is 'Remote control with "Terminal 15 on" active(1) inactive(0)'

This allows you to use a second key fob to lock/unlock pop trunk while the key is forward in the ignition engine on or not! If you're running a TDI in the winter you can leave it running, hop out, lock doors with second key fob, and keep your engine heat up a bit...
*Window mod does not work while key on
*locks out remote above 12 mph(in my 1J0)
*12 second delay after key on before remote works(1J0) -(caused a bit of confusion when testing)
*4.5 second delay after key on before remote works(1C0)

Searched all over the internet and haven't seen anyone figure this out on a MK4! Newer VW's can do this in VCDS soft Coding, but I've seen nothing on doing it in a MK4. Tested and working on a 1J0 Golf(x2) and Jetta, 1C0 Jetta and Jetta Wagon. I'm going to remote into last brothers' computer in CO to do his 03 wagon soon.

Hope you guys find this little mod as awesome as my family did!

gmenounos, Thanks so much for this program! I want your paypal to send in a donation! Everyone on here should too. You ended my 3 year frustration with trying to get the 1J0 window mod. I can't tell you how many desktops and laptops I've set up in the front seat and never got VDS-PRO to connect for whatever reason. Your program had it working in 30 minutes!

I had that on my 2004 BEW Golf for a while - window on when hatch open. So annoying. This was also like 3 years ago or so. So your rear wipers didn't activate when the hatch was open, but it allowed you to lock the car when running, as you mentioned above?

My rear wiper hasn't moved since changing that. Only allows key fob with engine running as far as I've seen. I have 2 Golfs and my brothers each have jetta wagons and no rear wiper action from that bit being on. 1J0 and 1C0 Golfs....

If you're trying to get the SKC from a NB cluster and you get the "Unsupported cluster software version" message, that's because there are two possible EEPROM address/size combinations and kw1281test doesn't know which one to use. You can try dumping the EEPROM both ways and report back to me which one worked:

.\kw1281test com13 9600 17 DumpMarelliMem 3072 1024
.\kw1281test com13 9600 17 DumpMarelliMem 14336 2048

I'm guessing that the 1024-byte EEPROM is for Immo2 clusters and the 2048-byte EEPROM is for Immo3 clusters.

Glad it's working for you. You can find my PayPal on the kw1281test page on GitHub ( https://github.com/gmenounos/kw1281test ). There's a "Sponsor this project" section on the right side with a link to my PayPal. I'd also accept donations of devices that kw1281test doesn't currently support.

Oh man. It hadn’t even occurred to me that, since I’ve got this operating on the command line, I could SSH into other people’s machines to get them set up. Sweet!

Glad you mentioned this. If my 8L S3 cluster doesn’t work out for whatever reason, I’d be happy to send it to you. Not even sure if that would be useful to you, since the pinouts have some distinct differences from (presumably) your bench setup. I’ve got the pinout differences documented though, so I’d send that along too.

Nice info! I will update my spreadsheet then! I have not heard of any updates since I made that sheet and I always thought the description was suspect (2nd hand) so I will add this in. Let me know if you run into anything else. Everything on that list was info I pulled from this site as I do not have a car to test anything on.

Thanks! Your spreadsheet was unbelievably helpful! Maybe put a note at the top about the 1J0 tab.... took me a while to find and looks like a few other people couldn't find it as well

Added the Remote with Terminal 15 to both 1J0 and 1C0 CCM listings and added notes to change tab at the top of each tab. If anyone has any other confirmations on any of the questioned items (either with a question mark or asterisk), let me know and I will update the list. Also, if anyone would like to add a car to the known list, please let me know and ill add the info. We need more 1J0 cars for comparison.

What is the Eeprom dump command again? it's been a month or so since I was trying all these... have a 1J0 golf and jetta, 1C0 jetta, Golf, and 2 Jetta Wagons. Currently modifed but I know what's changed to get the original binary

Funny you should say that, because I've had this 8L Audi S3 cluster —with adapter cable I built — sitting in a box for (checks notes) seventeen years waiting for Greg's incredible work here! But I have a feeling it'll be near-impossible to find any documentation of the addresses I'll need to modify in that particular cluster.
Very interesting! I had the same idea, do you still have the wiring diagram for the adapter?
