i had this same problem with mine , put it into the steelers and they changed it only problem was that they replaced it with a RED gti light . I didn't notice till i got home and when i called to find out what was going on they said that was the light listed for my car!?! ... 2 days of arguing with them and they are gona put the right one in , the only thing that realy anoyes me is that im gona have to pay for another trip to the dealers on the ferry !!!
This also happened to me, they replaced the light and when i looked at it i could see straight away that it was a gti light, i told them and they were bewildered, the lady came back to me 3 times and told me that the previous owner had changed the lights from standard
i had to take them outside and show them another edition 30. It was sorted eventually and they ordered the ed30 light for the next day.
I am going to take the lights out and try and seal them a little better, think i may need to use less water when rinsing it after washing as i tend to drown it
