    Hi all,


    Recieved some led bulbs and fitted them, both number plate bulbs are working but my number plate light warning on the dash has come on!


    Any ideas why?

    These are the ones from T8ups, I'm sure there is a reasonable explanation as to why its happening..

    Year of car helps to get you some advice/help, research the site also as this has been discussed a fair bit.

    I read on my travels that they may need coding at 2009 if its a facelift? I could be wrong.

    On a separate note... I have fitted the trups supplied bulbs and they are superb!! DRL's are brilliant as well!!

    Certain years, newer ones have the possibility to code the led number plate lights yes, but needs a specific version of CE board & firmware installed in order for that coding to be accepted.

    There's a topic about the cold weather making the bulb out light come on, happened to me so I put the OEMs back in, the others haven't really worked properly from day one for me. (2011 plate)

    I got a bulb out warning on mine last weekend when I went out for dinner
    with the wife. They were fine driving out there but after our meal the temperature
    had gone down from about 4 degrees C to -2.5 degrees C and as soon as I started
    the car I got the bulb warning, hopped out and checked and both were out.
    Switched off ignition, back on again and they were fine again. Just a glitch I reckon.

    Why not put Audi led's in which should work up to 2010 year if I'm correct, it's been a while since I looked.
    Mine have worked perfectly (2008) - just remember to bend the springs out (or there abouts) to match originals.

    Grab a cuppa and read this:
