The bulbs showed up this morning from Germany, but I knew the minute I opened the envelope that they weren't going to work
. Inside was exactly the same box that the last set I bought came in ..and they didn't work either!!!
It said on the Ebay.de listing that they are suitable for A3/S3 from MY2010, but on the box it says A3/S3 up to MY2009. THESE WILL DEFINITELY NOT WORK!!! It looks like Pretarion's solution is the only way we can have LED number plate lights without any DIS error at the moment. Sorry guys, I thought this may have been what we were looking for, but it seems that thanks to a misleading German Ebay listing, we are no further forward. My dad is very handy with electronics though, so I may get him to have a look at Pretarion's method and do this to mine.
