From my experience, the USB serial adaptors add latency which adds to the problem in most cases. I'm working on getting it to work but it will take a ton of time. All in my copious spare time. :D

Hm, I was wondering if timing was an issue... I noticed that there are a ton of timing numbers to tweak. My laptop is an old P133. I might try my newer laptop with a serial adapter to see if that works...

Actually, I have a PCMCIA serial adaptor, which I understand is a better choice than USB adapters where timing is involved... I'll try it out tonight and see what happens.

Guys, this program has to run in DOS mode. You can't run it in user mode in windows.

It works great on my 33 MHz AST laptop (the one in the pics)

compu_85 knows what he is talking about. i was going to boot to a flash drive into dos, but I found an old ME boot disk, chose option 3 (minimal boot) and she worked like a charm.

Are there other coding tables available, I was looking to adjust when the cold-start valve is activated.

i freaking love this forum. did this in about 15 minutes on a 98NB (IJ0959799AJ). thanks compu_85 for the link.
I didnt even read let alone write 16280 or 20916 as I dont have rears in the Beetle.
Works perfectly, thanks everyone.
MEM ADD - OLD - NEW
04283 - 154 - 2
04289 - 154 - 2
08628 - 242 - 246
12724 - 250 - 254

booted to dos via an old ME startup disk.
logged into 46 CCM with 19283.
My coding on a 2002 NB is:

04283 / 1
04289 / 255
08628 / 255
12724 / 255

Soooo........... Adding 4 is not going to work and I am not even sure if those are the correct addresses. :confused:

I thought for sure my old 25MHz 486 laptop would work but it just wouldn't. My 1.7GHz Thinkpad came through though!

I just coded a 2002 Jetta Wagon with a 1C0 959 799C CCM using the values listed in ELE28's post. Works Great!
I just tried my brother in laws VR6 with a 1C0 959 799 C and the original values aren't even close to what has been posted here and the posted new codes take but don't do anything. :(

Original Codes
04283 = 64
04289 = 255
08628 = 255
12724 = 255
16820 = 255
20916 = 255

What year is his VR6? We know that the later-model "C" CCM's, like the one in my 2004 Jetta wagon, don't have the right bytes in the places we're expecting them. The KVW100 apparently works correctly, but we don't know what it changes and where. For the time being, we can't program the late-model "C" CCMs with VDS-PRO.

I am guessing it is one of the newer ones. :(

I am striking out here. 2 for 2. :(

Tell me if you see these values at these addresses:

Address / value
04361 / 138
04362 / 138
04363 / 138

where do these memory addresses and values come from, are there tables? For example, which set would stop the fault code for a failed/nonfunctioning egr for say a rally race?

We're taking about the Convenience Control Module here, not the ECU. The Convenience Module has nothing to do with the EGR.

None of the information posted will help you with your EGR.

you mean I cant turn off the egr with the remote?
I was just wondering if there were data sets for other modules, particularly the ecu relating to sensor dataflow. Thanks for the clarification though.

in the spirit of the vag-com locator threads, is there anyone within reasonable distance of central MA with a working laptop setup for this mod? i just dont have dos 6.22 or win95 lying around any more, and my czech is pretty darn bad

I've got a Toshiba TECRA 8200, have a genuine Ross-Tech ISO-COM, and can boot into good old DOS using the CD image posted on Passat World (where I actually found out about this mod).

Once I open VDS-Pro, though, no matter what port settings I use (I know I'm on COM 1), it can't talk to the car. I've tried setting the baud to 9600, tried letting it determine the correct baud, and no joy.

Does my problem lie in my laptop or in the ISO-COM? Has anyone used an ISO-COM sucessfully?

I'm in the process of making my own boot CD to see if that may work (and so I don't have to remember german keyboard layout), but in the meantime, any help would be appreciated.

Thanks!

iso-com = opticable, correct? my understanding is you need a "modern serial adaptor" (or jump through some hoops discussed in this or one of the other threads... had something to do with "portalk" ... to use a usb cable) compatible with vagcom v409. i tried an opticable and could not communicate.

ISO-COM is the oldest Ross-Tech cable out there: OBD-II to RS-232 via opto-isolators.

If the porttalk route would make this work, it would be easier than getting a "new" cable...

Recoded mine today and it worked. My CCM is 1C0 959 799 C in a 2002 Jetta GLS.

Address / old / new
04361 / 138 / 130
04362 / 138 / 130
04363 / 138 / 130

Excellent, we have the first 2002, 1CO...C ccm double din.

No 2003's or higher yet....

Lito
MOdified GMark's 2004 Jetta sedan as above. Only necessary to change the first two values. His is equipped with the 1C0...C.

Didn't have the time to find the combination to disable key but leave fob enabled. Found a combination that disabled both, or disabled the fob completely, but not the one we wanted. Perhaps some other day or night. Storms moving in tonight.

This just leaves Jetta Wagons as the mystery vehicle if I read this thread correctly.

Great! Glad to hear those values worked for you! I haven't played around much with it. I'll try to put the third value back to original and see if it makes a difference with mine too.

porttalk was to let this work though windows and no one was able to do that successfully.
Darn - thanks for the info, but I guess I'll have to find someone to borrow a cable from locally, or go build one myself.

I did a little more reading on the Ross-Tech site about opto-isolators - and learned that their problem is that they tend to garble up the waveforms going to and more importantly from the car. So, when timing is muy importante... no joy.

Anyone in/around DFW have a "modern" ISO-9141 to RS-232 cable? We should meet up :D... if not, I may just buy some ICs and polish up my mad soldering skillz.

On another note - has anyone tried this on a Beetle? (1C0 ...-F or -G) I will, as soon as I find/get a cable...

Nate, you can get a KKL cable from ebay pritty cheaply. Or for $60 you can get a Uni-Com brand new from SenSolutions, the people that made it for Ross-Tech.

Thanks for the sources... although I still enjoy a good DIY build, that may be easier.

Just looked on eBay - Has anyone bought & used one of these? That's cheap... and only a couple of hours from me.

FWIW... I've tried this cable (eBay Link) using a Dell C600 labtop with the Boot CD with NO luck. BTW, the cable works fine with VAG COM 409.

Still looking for a solution... :mad:
