Hello gmenounos, do you have any pointers for me?

I just used the values here: https://www.vwvortex.com/threads/diy-windows-roll-up-and-down-with-remote.4822256/ for my CCM (1J0 959 799 AJ)

Hello Mozambiquer, can you please let me know how you managed to do it? Thank you so much in advance!

For the hatch unlock on my Golf I changed bit one on addresses 04280,04286 and 04292 to zero, going, in my case from decimal 204 to 76 and that enabled the hatch unlock with the doors. I am not sure if the Passat and Jetta wagon are the same.

...and this was on a 2001 car?
If so - that's GREAT information! Friend's 2001 car with manual windows and we were trying to get the hatch unlock to work, but I didn't know to look at those addresses. Will give it a try for sure.

Yes, that was a 2001 Golf. I'm not sure if jetta or passat are different, and also not sure if the one with manual windows will be any different.
Obviously the number returned may be different

Does anyone have a backup of the CCM EEPROM values for a 1C0959799 CCM in a 2002 4-door golf? Specifically addresses 4352-4372. I was trying to get the hatch to unlock with doors and now have several oddball problems with my alarm, locks, and lights.

04354 08
04355 88
04356 88
04357 88

Thank you! Are those values all in hex or are some in decimal?

Adresses are Decimal and all values are Hex. Sorry, I should have made that clear!

Alright so these values are for the 1CO959799B and I have the 1CO959799C, do you think that it will be any different?

Hi. I have a problem. Passat B5.5 Wagon, 1C0 959 799B
I try to activate trunk open via remote. Changed 04361-3 from 75 to 68, and 04367-9 from 255 to 253. Now i can't open trunk from outside, VCDS shows fault code: 01141 - Luggage Compartment Unlocking Switch (E165) 27-00 Implausible Signal . I'm go back to previous values, but nothing. I can't open trunk. Is this possible? Any ideas?

Off the top of my head - some CCM require a reset for coding to take effect. You may have to lock it for a hour and try again. Or disconnect battery for 1/2 hour and retry. Sometimes these CCMs don't like change.

Hi,
I have retrofitted my golf mk4 with power windows.
I used a 1C0959799F CCM from a seat leon, this allowed me to still use my old 1j0 style speed, door open, and ignition signals.
I changed these bytes (decimal) to enable remote windows and the alarm.

Code:

Remote window activation
04361: 10 -> 2
04362: 10 -> 2
04363: 10 -> 2

Alarm activation
04355: 17 -> 16
04356: 17 -> 16
04357: 17 -> 16

This both functions fine now, but I still have two remaining problems:

My car doesnt have a sunroof but the ccm thinks it's open (Does this have any concequences?).
When locking the car immediately blinks/honks, instead of blinking/honking after all doors are properly locked like it used to. So its not a confirmation that the car is locked now, its just a confirmation that the signal from the key was received.

Does anyone which bytes/bits might have to do with this?

Edit, some more info:
Eeprom values:

Code:

Coding: 00259

Adaptation:

Code:

1: 1 (Number of keys -> 1)
3: 0 (Auto lock -> OFF)
4: 0 (Auto unlock -> OFF)
5: Not availabe (Interior monitoring)
6: 1 (Unlock horn -> ON)
7: 1 (Lock horn -> ON)
8: 1 (Unlock blink -> ON)
9: 1 (Lock blink -> ON)
10: 1 (Country setting -> Rest Europe)

Can you also provide the values from 4367-4369?

Why did you change 4355-4357 from 16 to 17 and what did it change for you?

I have a running list of codes from various cars around the world so all of my suggested changes listed below are coming from other cars:
4352-4354 -- 255 -> 8 (This might fix your sunroof issue)
4364-4366 -- 240 -> 60 (for no audio feedback) OR 252 (for audio feedback)
4367-4369 -- Unknown but usually 255. Please provide before values before changing.

Let me know what you find. I have a list of what I know or believe each config bit is but some items I still don't know the exact setting it configures but these values are based off of other RoW Golfs.

Thanks for your reply!
Forgot to post 4367-4369, but they are already 255 for me.

Changing 4355-4357 from 17 to 16 enabled the alarm for me, although I do not have the hood contact switch wired. But unlocking the rear lid through the lock cylinder does set off the alarm, so it is working.

I'm on vacation right now and dont have my obd cable with me, I will try the other values next week.

About value 4352-4354, is it known what this value does? I'm affraid of changing whatever value affects ignition through CAN vs wire and that locking me out of my ccm, because I dont have the CAN ignition signal.

Not sure if this helps you, but I found this in a thread a while ago and found it useful to understanding some bits.

anyone have this 'table' for 1j0 959 799 ah ccm for golf mk4 3doors??i'm looking for stock values of this ccm.

lijetta18t · Aug 15, 2023

Here is a re-post of my spreadsheet with known and unknown (but thoughts) of all of the values in the MK4 CCMs from the 1J0 to 1C0 modules. This includes some default values from stock and modified cars.

Link to DropBox Excel File

Remember, anything with an asterisk (*) is unknown but it includes my educated guess of what it controls/performs. I am looking to see if anyone can confirm what these bits do to let me know so I can update the sheet. You can also send me the default values for any stock cars. Just make sure you include the CCM part, Model, Year, Options (sunroof, door count, alarm system, etc).

Nuje · Aug 15, 2023

Fantastic! Thanks for posting that. I don't recall seeing the breakdown like that for the 1J0 CCMs before.

i did the roll up/down windows with key fob in my 1j0 959 799 ah ccm

Memory Address old value new value
04295*** 138/ 64
04283 138 / 64
04289 138 / 2
08628 242 / 246
12724 250 / 254
but i lost the function roll up/down windows with key.when i lock the car with key and keep for 3-4 seconds the key in lock position or unlock.

Try:

04283 = 128
04289 = 128
04295 = 128

If this does not work or causes other issues, change the 128s to 2s. Let know if this works.

thank you lijetta18t.i didn't change anything..i make a mistake.i change the 08628 to244 and 12724 to 252.i read somewhere that is more safety with this option.if i need to enable the key up/down i must change the 08628 to 246 and the 12724 to 254.instead of changing the existing by 4,if you change it by 2 it disables the key roll up/down..

Shouldn't 04283, 04289 and 04295 be the same value? Why would 04289 be set to 2 with the others at 64?

Correct! All 3 memory addresses should match whenever one is changed. Also, not sure why 2 or 64 would be good options as changing from 138 to 64 disables bit 7, 3, and 1 and enables bit 6 which makes more changes than I would expect. 2 is the same thing as it disables bits 7 and 3. I would think if you have 138 by default, 128 or 130 would be a better option. The former allows the hatch keyhole to allow comfort windows and the latter blocks them.

Are you absolutely sure the list you provided earlier shows your valid stock coding?

you are right. I messed up at some point.maybe the 04289 addres have wrong old value..I asked for stock values but no one have them.
but also with these old values the windows working good.so i put the new values and the windows rolling up/down works great..
