    You have 3.7, I've got 3.62, where'd you grab that from then, lol.

    So you need to check your wiring against the 09 wiring for a car that has the 30 byte module, so ask someone with a facelift car with xenons with the N module what there engine code & car info is so you can go through elsawin & compare, this should lead you to see wiring differences mate.

    I just got it from torrents.ru :)

    That's kind of a long shot for me... Where do I get car info from a matching face-lift model (mine doesn't have xenons yet)
    Can I just fool elsawin and enter a higher year in vehicle enquiry?

    You can ask anyone on the forum mate, they would be glad to help, you can enter what year you like but it needs the engien code really to pull up right info.

    You have yours so just need a comparison for a later model, then can check the illumination circuit wire by wire, whats your engine code & gearbox.

    I've been looking in elsa for 2009 model and wiring seems (a first look) different.
    Probably it need more than 3-4 wires to be moved :(
    Problem is that I have to take ALL of wiring and compare them (big thing for me :))

    So, I did some compairing some connectors G and E from 2007 and 2008 (http://www.audi-sport.net/vb/showpost.php?p=770439&postcount=28) and the wiring are identical...
    Elsa doesn't separate clearly the models... It's says from May 2006 or for model 2007 onwards...
    For new models it says from May 2008. So an engine and gear box code from a 2009 model is useless.
    Will compare others connectors too, but I have a feeling that they will be the same... :(

    Did some thinking... Can this be because I installed full interior led's with resistors?! Maybe they are throwing off the car electronics and "think" it doesn't have any ambient lights...
    Will replace with stock bulbs to see what happens.
    Unfortunately it got cold over here and can't check until spring...

    urgh, sounds unpleasant!!!! -5C isn't too rare here but I'm on the coast too so little snow. I rememember watching Rangers playing a Ibrox and none of the toilets or stalls worked as they were frozen, even the Clyde was frozen over.

    I am having this same issue with revision P after installing European tail lights on my American 09 Face lifted A3 and coding with ver 10.6.0. I'm not 100% sure that the coding alone caused the "flashing" symptom, but if it helps - the last coding changes I made were in byte 24 and byte 25. Has any progress been made on fixing this little "issue"? Also, if any more info is needed from me, let me know....

    You know, I didn't even realize before posting there, but that thread is about a different control module (8P0 907 063 A). They're posting useful info, but not for my situation. You say that your "audi friends" helped you? Does that mean a buddy at a dealership? I'm getting close to going to a dealership nearby to see if they'll work me a favor for cheap...

    If I wasn't so busy at work for the next week, I'd be more active on this and call Ross-Tech and Oemplus about it. Maybe I'll wait...patience is a virtue right? Besides, it looks like a dance club in my car at night.

    A little thread resurrection :) I bought a brand new central electric (8P0-907-279-P). I've got rid of christmas lights but now I have no ambient lights. Also headlight switch, ESP, TPMS, cup holder don't lit as well...
    Coding again was made with print screens of old one... Don't know if I should tick "speed dependent trunk lock active". Did they fix this?
    Any ideas? NHN?

    The labels would have only been corrected on an update of VCDS.

    Useful thread, shame couldn't pin-point the exact problem. I'm assuming you replaced the LED's wit the stock bulbs without any luck?

    you still having problems! I went for a k revision, had no problems. What headlight switch you got? If the light dimmer switch isn't wired/correct you won't get dash lights working.

    I'm not sure what it's now, but will be buying this 8J1 941 531 G as I recently retrofitted bi-xenon adaptive headlights.

    If anyone has wondered, this is the coding that 8P0907279 P module has from factory 008C5F040014108040000000000000000000FE075C020000000000000000

    Breakthrough!!! I managed to get rid of blinking led!!
    I started from factory coding and changed one bit at a time, and found out why I had this problem. It was a tweak of mine, as I wanted my turn lights turned on at 15% all the time. (Cool little feature - sad to let it go)

    I've set it back to 128x1 and now it's perfect. I can put this to rest!!

    I'm having the same issue, interior leds on my nav/climate control/door switches flickering like crazy. What does setting the turn signals to 128 do? Wouldn't it be set to 0 from the factory? Mine was set on 0 on my factory unit. Any other suggestions for me?

    I'm having same issue...
    I did an update from 8P0907279F to 8P0907279N and my navy, steering buttons, climate, looks like an Christmas tree...
    Any ideas to solve the problem?

    Just to inform that my problem was solved with the drsilviuro solution; bytes 7 must have 128 in those cases.

    Hi all,
    My climate control, radio and door switches look like a Christmas tree when lights are turned on...I took drsilviuro advice, this has stopped the flashing but I've notice if you set bytes 7 to 128 the dimmer switch does not have any affect on the led brightness, they stay bright.
    Anyone else found this to be the case?
