Hi

Fresh VCDS user here. Been using the tool since Christmas (Christmas present to myself), and slowly starting to get into it. I'm mostly just doing minor cosmetic adjustments with VCDS, anything else is way beyond me.

One thing I'm having trouble with, is controlling how/when the bi-xenon is used. I've already coded the "Coming Home" and "Leaving Home" functions to use the fog lights, and not the xenon lights. Currently when the light switch is in "Auto", the xenon lights are always on. I want to avoid using the xenon lights for every little thing, to preserve the bulbs. What I'm trying to achieve is this: When the light switch is in "Auto", and the light sensor says it's daytime, the LED DRL should be on full brightness front and back, and the xenon off. When it gets dark, the xenon should automatically turn on.

I assume this is done by coding in the "09 Cent. Elect". But there are a lot of undocumented bits in the long coding helper, and I'm very wary of experimenting too much with unknown bits. Is it done by some of the undocumented bits or in "Byte 18" maybe? Been Googleing this for a couple of weeks, but to no avail. Seems like my car model is not all to common, at least not in the US, and I'm having a hard time finding info for this specific model. It's a 2011 Passat Highline, 3C/B7 (Variant 365) Euro, with original bi-xenon and LED in the front and back.

Any feedback is greatly appreciated.

PS: Found and confirmed a couple of undocumented bits. Is this something I should post on the forums?

Nice first post. CODE tags and all. :D

I don't know the answer to your BCM configuration questions. Hopefully someone will have some ideas.

You are correct, NAR (and China) get a completely different "B7" Passat than the ROW.

By all means feel free to post your findings regarding undocumented bits.

Thank you. Well it's not rocket science :)

Can I do any real damage by experimenting with undocumented bits in "09 Cent. Elect"? Except from "Byte 18", seems like most changes can be reversed, and are mostly not critical?

Have registered using the same name and email address. Got a a confirmation email from Linda Ross yesterday.

Thanks for registering. You're a Verified User now.

My understanding (somebody correct me if I'm wrong) is that even Byte 18 changes can be reversed, IF you know what the original value is. Unfortunately, yours is masked with 00. I'm not aware of any other bytes that have such issues, but if there are any, somebody should chime in here.

Fix a issue with Light Switch. This might be a problem why you have lights all the time.

Have solved this "problem". All the coding was correct all along (as I frustratingly thought while testing). The problem was the how light sensor works and the setting for the light sensor. My lack of knowledge and understanding of this, led me to make a few wrong assumption. Which explains why I did not get the results I expected.

  • I believed the light sensor used the same light levels to govern the "Coming Home" / "Leaving Home" function as for the bi-xenon headlights. It does not. The CH and LH activates at lower light levels than the headlights. So using that function as an indicator was really bad.
  • I believed the headlights would recognize the daylight conditions, and simply just not turn when turning the ignition and/or starting the engine. When actually the bi-xenon headlights will turn on, and with daylight conditions detected, turn off again after a "short" while. I guess this makes sense, as the xenon level calibration is done at engine startup.

I re-tested using a strong work light, and things were actually working as I wanted. Now I could go on to adjust the sensitivity of the light sensor to tune when the xenon light go on/off. In the ECM, subsystem 2, Byte 1, Bit 0-7 Light sensor correction: I dialed down the sensitivity from 48% to 10% using hex values as no predefined option was available for anything lower than 43%. I'm guessing there will be some further adjusting as I drive the car i real life situations.


Just wanted to follow up on this, just in case somebody else was wondering. Thank you for the inputs.
