Hi I am new to the forum so hi to you all.

I was wondering if anyone is able to help me with issues i am having with my alarm on my wife's 2004 2ltr petrol Beetle? I think i may have a bad CCM but hoping someone can provide some assistance.

The alarm will sound randomly and can be in any weather or anytime of day. I have put the car into a garage and they diagnosed the Driver side door lock module as being faulty (common issue i have gathered). They replaced with a genuine VW part and i took the car back feeling happy i can now get some sleep and not panic about it sounding in the middle of the night.

Sad to say that this has not cured the problem. I managed to get a local lad to scan the car with VCDS as i at the time did not have the full version and got 3 error codes. 1st was saying Key 2 had surpassed adaptation (this has been resolved by syncing the remote again with VCDS), 1 saying no communications with the door module (cleared and not come back so thinking this was the old code) and one saying control module incorrectly coded. This last one (detailed in VCDS scan below) will not go away.

I have recoded the module several times with VCDS and it still comes back. Everytime i do this though i have to re sync the remote with the car. I have also check the following as advised by others and internet suggestions as to what maybe causing the alarm to fire off.

Battery Voltage = ok
Fuses = ok & none blown
Boot latch module = ok, no leaking from brake light on the boot. no wet patches in boot
Windows = Work fine
Interior lights = will not turn on when doors open. This goes for driver and passenger side but they will turn on if you do it manually.
Wiring in door = Check and cannot see and breakage or damage
Passengerside door module = Good and connection is fine
Last 4 alarm triggers = VCDS cannot read the last 4 alarm triggers. When i try to read the measuring block the label file suggests it comes up with "Error group 0XX not available"
Radio = Have check the radio connection (aftermarket radio) and cabling. all good.

The interior lights issues makes me think that the CCM maybe bad and causing these issues with the alarm as well. Coupled with the fact it will not let me read some of the measuring blocks. to be honest i am at a loose end with it and running out of ideas.

Full VCDS scan is as follows. Any assitance would be great. Thanks

So, far... it looks like you have thoroughly checked the most common faults; those being broken wiring in the door harness (from body to door; that flexes) and the door lock module (bad microswitches/cracked solder joints).

As for your current trouble code related to your alarm issue; there is a note about a bug in the ccm on the new beetle:

01044 - Ross-Tech Wiki

According to Ross Tech; you may need to "refresh" the coding with the same code that is shown and this overwrites the code and this seems to bypass the bug in the computer.

Aside from checking over the wiring and door lock modules we have discussed before; I would be looking at refreshing the ccm and see if this allows you to access the measuring blocks. The fact that you cannot access it and ross tech says there is a bug; then, that looks like something you should work through. As for a bad module; we have had some members here who did have a bad one but most of the problems with the alarm seem to the door lock module or when things don't work, the wiring harness is compromised. The wiring to the comfort control computer; where you say you have no communication, should also be checked as well. Historically, when communication is down; it can be a wiring issue or a component, has a hard failure and this brings down the communication network. At that point, finding the offending part or wiring issue; is the next thing to play "detective" and find.

Other problems that people have had; as mentioned in the ross tech site, is when people have knowingly or unknowingly had used or new incorrect parts installed in the car. There were running changes that VW did to the new beetle and there are actually different parts, for the duration of 1998-2010 model years. After close inspection, some members have found; their cars were "hacked" by previous owners or they tried to install "junk yard/breakers" parts but not making sure they were the same or compatible parts needed for their particular new beetle. So, keep this in mind and if you know the history of the car or inspect the door and ccm computer, for incompatible or used parts. Another thing, is we have had people install aftermarket parts; like the door lock modules, from China and they have had issues with them, causing problems (functional, electrical and premature failures). So, that is another area to look out for; genuine VW parts are preferred and aftermarket less expensive parts, can potentially cause problems as well.

Thank you for the great reply. some of the resources i have come across but good to know i am checking the right things.

You mention refreshing the ccm. do you mean re entering the soft coding on vcds or via another method (disconnecting the battery/fuse?).

are you able to advise me on how to do this. just so i know the correct way?

onve again thanks for the help so far.

Based upon the ross tech site; the central convenience would need to be recoded:

Possible Solutions
Check Gateway Installation List
Check/Fix Control Module Coding
See Vehicle Specific Diagnostic Procedures for Details


Check/Fix Control Module Coding:

example shown: Ross-Tech: VAG-COM Tour: Recode

So, you would need to choose the "46: Central Conv."

VW New Beetle/Cabriolet (1C/1Y/9C/AG/AL) 1998 - 2010

http://wiki.ross-tech.com/wiki/index.php/Diagnostic_Procedures

Note the procedure listed on the New Beetle page:

then choosing the appropriate version for your car:

Comfort System (Generation III) (MY 2002 >)

[46] - Comfort System
This module applies to vehicles with Power windows. See [35] - Central Locking for Manual Window configurations.

Comfort System (Generation II) (< MY 2001)
Coding
Adaptation
Label File
Comfort System (Generation III) (MY 2002 >)
Coding
Adaptation
Label File

Then click on "coding"; look at the video on the end, for a example of doing this.

For specific step by step info and coding info; if things are unclear, I recommend posting in the ross tech forums here: Ross-Tech Forums Post in the "new user forum"

I have not done this procedure myself but it seems relatively straightforward process but sometimes, what ross tech posts how to do things on their site, can be somewhat unclear. All registered users of the ross tech vcds scan tool that are registered can access and post to the support site.

I had to code a new speedo cluster and they were able to help me do so and I successfully completed the coding process. So, they are responsive to questions and are willing to help, if you need it. I hope this helps!

Hi,

Just a quick update to say i rechecked cabling and also ordered a new CCM module from the web. I did manage to find a couple of cables with slight nicks in them so i sorted these. I would say not enough to short out but still repaired them.

I also fitted the new CCM and re coded it. Suddenly now all the interior lights work, radio retains memory, i can read all blocks/codes and so far to date (touch wood) no alarm triggers. I am guessing it was the CCM all this time.

Will update again if anything changes.

Cheers for your help.
