Hello,
I just purchased (picked it up yesterday) 2006 M3 HB. I think, this is GX model. (very basic one). While driving it home, I noticed that the low beams are very ineffective - it appeared to me that they were stuck in DRL mode. I have projector low beam with separate high beam reflector. Now, I tried searching, but I could not find conclusive answers to the following and I was hoping someone could help me:
1. I thought that DRL use high beam reflector, but supply lower voltage - is this true for all models or there are some models that use low beam projector as DRLs.
2. If low beam projectors are used for DRL - does the voltage drops or there is no difference between DRL and low beam?
3. If the voltage drops for DRL - what is the value?
4. Besides checking voltage - is there anything else I can check? (I am somewhat technical inclined)
Thank you so much,
Bez.
