If you've plugged the section B wire into the the 2nd bulb of section A for the on-LEDs, THAT'S why it's always on. Both those non-LEDs DO get the exact same signal from the BCM2, because they need to - just to light up evenly section A in those lights.

This is the real problem - there is NO separate wire for the brake light in the non-LEDs. The wiring diagram for the non-LED confirms this. I'll send them to you too. Section B therefore will ALWAYS act just like another section A bulb in the non-LED wiring, and unless/until you recode or replace the BCM2, you will NOT be able to segregte them.

I am curious though about the brightness in your case. Are sections A & B lighting up half bright as tails, and then full bright as brake? And then similarly as turn signals too? If that's all true, then that's as far as you can go. Of course putting in the resistors will block the bulb-out faults, and you should have the outboard reverse lights too, and even the side markers too.

When you say everything works as normal, then I think that's all you can have. Unplugging the section B wire is your choice then for the same tail signature as a reguar A5/S5 with LEDs. To have it work as brake and signal too, you'll need to code or change the BCM2. Sorry ...
Yes, sections A and B are lighting up half bright as tails and then full bright as brakes.

I have just left B unplugged for now.
 
just FYI, kufatec is sending me out a dongle to put everything back to fact settings

can't wait to have my car back to normal.
Please tell us the instructions - and how well this goes for you -
 
Roger, did you receive the dongle today? Sigh... i'm starting to miss driving my car
I did receive the new dongle late this afternoon, same version as what I got originally. I'll post as soon as I get a chance to check it out.

I noticed that I didn't get any bulb out errors while driving today. It's weird because sometimes I get the errors and sometimes I don't. I am not running any resistors right now either, just plug n play minus the B wire.
 
A recap of wiring - just for reference

Hope these help - may not be perfect ...

THAT is a bit weird w/o resistors. But until you use the circuit that's looking for bulbs is on, it won't detect - that is, if your lights are off and you don't step on the brake, the bulb-out won't appear. Have you reset the faults with VCDS? That will clear the log of them too.

and, if you're driving without lights during the day so what?, but if can do that without brakes, man, I WANT a ride with you!!

Haven't reset the faults yet. This happened with the lights on, so it's a little strange. I got excited because it did it twice in a row and then the third time they came back on lol
 
Well, WOW ! at least I got amber signal lights now with the new dongle!! Brakes and tails still work correctly too, but alas, i still have bulb-out faults and NO reverse lights.
ALL coding was done exactly as directed by Kufatec and the dongle LED did go out after about 30 sec. I will report to Kufatec and see what their next move is ...

Stay tuned -

Ahhhh. So close! Hopefully they can sort this out.
 
Sorry that it's not yet perfect. While I'm encouraged at making progress, I'm not quite cool, as it's still taking way too long while they've had our money. I'm also a bit curious that Kufatec was talking about a new version of the coding, but didn't send me that one. Perhaps it's not relevant to our issues, but still, if it's this close, why not send me a bootleg anyway. Obviously those guys have a pretty good understanding of the BCM2, more than folks who just replace it, so I give them props for that, but so too, they still need a bit of fine tuning to get it right and ready, which is what we all paid for.
 
Had at another round with Kufatec this morning. Unfortunately I cannot spend my day job running enough data mining for them (or us, as they can't/won't respond to us until I can provide more). They're now saying they do not change anything for reverse, but that is NOT true, as my BCM2 now no longer has any outputs on the pins for those wires at all (and didn't after the first dongle failed). So not sure where we really stand.

They're (Kufatec) are also getting a bit testy, not wanting to have any dialog - just email facts, so Nima can "clear his desk" - frankly, this frustrates all of us. I'm spending more money and time now than I can possibly recover ...

Robert - I hope you're paying attention. Don't trust your suppliers until you have PROOF. Apparently Kufatec trusted 'someone' in the US for a first test, and now just sends the rest of us, that coding, in the hopes that all is well. Well, it's NOT.
 
not sure if you were talking to me, but i put my stock lights back on and my reverse doesn't work and the lights on the trunk don't work either. not to mention it shoots out faults.

so this new dongle is suppose to bring everything back to normal.
 
Sorry Robbie, yes my question was directed to you. So you have blinkers then?

Also I'm sure your license plate lights (festoons) shouldn't have been affected by this. Try checking the cabling that leads to it. perhaps the ribbon cable must have disconnected.
 
Just to recap for me. I have working tails, brakes and signals in all the right (EU) places. I also have bulb-out faults and NO reverse lights. I am functional and Kufatec is still working with me - but I must say the relationship is getting a bit strained, as they must think I am a car mechanic and only to happy to skip work to poke around looking for pin voltages here and there - This last part is particularly frustrating to me, as I had ALREADY done some of that and found no reverse signals on the BCM2 outputs (at the box). So if they're not coming out of the box, they will NEVER get to any wire going to the lights. Yet Kufatec is asking me to check voltages and crossed wires at the harnesses.

Further, they claim they cannot see the US wiring but the US and EU are on the SAME diagram, so I have no idea why they're copping out on figuring what the US BCM2 should be looking like. I'll give them the exact pin with no signal for/from reverse to see what they plan next. Probably a new dongle just to code the BCM2 for that. Then another to take care of the faults - yikes:

So I believe my lights that I returned have been delivered but I have yet to receive my refund or hear from Robert, I tried to contact him as well.

I hope I'm not dealing with another problem now...


**edit** Just received a reply that he needs to pick it up from customs.
