Hi I just ordered new ballasts for my 04 530d adaptive xenon D2S setup.
I ordered part number 2 x 63126907488 which according to realoem are correct for my D2S setup.
What I have received is 2 x 63126937223 which according to realoem are ballasts for a D1S setup.
Can anyone confirm if there is commanality between these 2 part numbers i.e. will these D1S ballasts work in my car?
if memory serves the D1S has an ignitor integrated into the bulb, don't think its the same.
I had a bora that a retrofitted factory xenons to a few years ago and I had to order a ballast for it too. I found the best source was ebay germany.
The german word for ballast is steuergeraet, so model number + steuergeraet should see you sorted for the ballast. Try to get the bosch, or whoever the OEM is model number.
I found that the one for the bora was being used in a litany of other cars and ironically, the same part for a merc was way cheaper, go figure.
Take them out and try them according to this some pre lci e60's with bi-xenon use d1s and d2s
