howdy,

Thanks everyone for the great resources on this forum!

This weekend I coded my 2012 F30 335i with:
- VO code Anti-Dazzle and VLD (removed 5AP, 8S4)
- VO code Sports transmission (replace 205 with 2TB)
- FA edits to make mirrors fold from key fob
- ... and a few other small tweaks.

Nearly everything works perfectly. The 2TB and anti-dazzle make my 60k mileage car feel new!

So. The weird problem.

My passenger side (right) mirror turn-signal LED no longer turns on are really dim. I confirmed it does not seem to function for Lock/unlock, Turn signal, Hazards.


Ideas? *I think* it worked yesterday. Could it be a coincidence that the LEDs stopped working the same day I coded? Is there a coding option I could have mis-clicked?

I searched ... but I did not find.





Update:

It isn't broken! It's just really really really dim and I couldn't see it in full daylight. So. Same question, different symptom.

Which headlamps do you have on your '12 F030? I would be surprised to NGHB working with just VO Coding.

Did you scan car with ISTA+?

Per BMW VIN my car has:
5AC* AUTOM. HIGH-BEAM HEADLIGHTS CONTROL*
5AP* DECODING FOR NO-DAZZLE HIGH-BEAM AS*
524* ADAPTIVE HEADLIGHTS*
8S4* DECODING VARIABLE LIGHT DISTRIBUTIO*

I removed 5AP and 8S4 from the FA list and recoded FED_BODY and KAFAS2.

I don't have access to an ISTA+ scanner to see any insights.

Did you also code the lighting modules? Do you have TMS/LHM? Make sure you have the correct hardware.

You can get ISTA+ here.

I'm still learning so I'm not sure how to answer your questions yet. Little help on how to check what hardware I have? Is there a part number listed on the headlight module that I can find in the car itself?

I'm currently using the F30 Coding Reference Guide cheat sheet available here:
http://f30.bimmerpost.com/forums/sho....php?t=1020138

From my personal experience after removing 5AP and 8S4, the car appears to behave as shown below. Before removing the decode attributes the car's auto-high-beam control only made the brights flip on and off.

Back to the original question - dim turn signal mirror.

I went and took a video while it's dark outside to see what's going on. As it turns out, the light panel looks like it's usually dim but flickers to be full brightness. Strange!

There is a part number, but not sure where to instruct you to look. The previous linked thread with part numbers may have more details.

See this guide.

Thanks!

From this quote:
"2 Unfortunately, adaptive Xenon headlights fitted by BMW on US cars lack the required movable mask (or walze in German) needed for the dynamic shadowing and thus are physically incapable of supporting GFHB. By contrast, BMW adaptive LED headlights achieve the dynamic shadowing by pixel light and thus do not require the presence of the walze."

it sounds like by me removing the de-code without also swapping out the Xenon module's for either LED modules or non-US Xenon modules I won't get the appropriate shadowing effect.

Does anyone know enough about the technology to know if that having no shutters in the Xenon means that I risk blinding people? (in which case it goes back to stock...)

You could keep the VLD. But, unless you have the European Xenons or LED's, you would not have proper equipment to shape highbeams.

So I was totally wrong about it being correlated to coding. It just happened to be a turn signal LED going bad at the same time as when I started coding.

So:
Part https://www.ecstuning.com/b-genuine-...a/63137280772/
Take-apart http://f30.bimmerpost.com/forums/sho...0&postcount=39

Everything is back to normal!



Also I did put the anti-dazzle and variable light distribution de-code back in place. I really liked the dancing headlights ... but I like not blinding people more.

I looked into retrofitting my car with the european anti-dazzle compatible parts (which include a separate mask inside the module) or upgrading to the LED headlights. But, all options are insanely expensive and not worth it to me.

After removing 5AP, 8S4 wich module did you code?
