Hello, guys

Got the following error when scanning with VCDS:

Code:
02234 - Right Headlight Power Output Stage (J668)
            002 - Lower Limit Exceeded - MIL ON
             Freeze Frame:
                    Fault Status: 11100010
                    Fault Priority: 4
                    Fault Frequency: 1
                    Reset counter: 194
                    Time Indication: 0
After reading here, I've understood that the AFS module is kaput and decided to change it.

Did some research and I've found that the Passat bi-xenon AFS module is matching with this one and found one from a guy who was dismantling his car.

I've put the new module on and VCDS was saying this:


Code:
                Address 55: Headlight Range       Labels: 7L6-907-357.lbl
Control Module Part Number: 7L6 907 357     HW: 7L6 907 357
  Component and/or Version: AFS-Steuergeraet    0003
           Software Coding: 0000003
            Work Shop Code: WSC 31414 000 00000
           Additional Info: 7L6941329   AFS-Lst.-Modul l    X018   7L6941330   AFS-Lst.-Modul r    X017

I think the modules are not so compatible after all. The one from the Touareg had 7L6 941 330 (R) and H6 SX 18 while the Passat's module had 7L6 941 330 (R) and H6 SX 17.

Is there a way to make them work? I've tried to get the long coding from the broken module and overwrite it with the new one but I couldn't find this option on the 55 Headlight Range from the VCDS.

Thanks

As well, when I try to do basic settings on new module I can’t access any group even if I put the adaptation code on security login.

I can write, but I tought that it's not an interesting post for anybody, since I had almost 200 views on it and nobody said anything. It was an euphemism as well from me, Tommi.

The fix was that I've taken out the module, put the old one, got some measurments with VCDS from the faulty one and when I've put the "new" one back, the high beam wasn't working. I've pressed the headlight a little harder in it's position and then I saw there was no more blinkin' light on the dashboard. Scanned with VCDS and everything went smooth.

So, if everyone is wondering, the AFS module from Passat is working on Touareg, but I think it has to be RHD for RHD and LHD to LHD, not the other way around. I am not 100% sure about that.

Thanks for updating us. People are always interested - your post being read 200 times is proof of that - but sometimes no one has a bloody clue!

Hope you can see where you're going now.
