Vista DRL do I still need it.
My car is a 2007 E90.
Bought a Vista DRL harness already as my car is a Sept 2006 built date.
There is a emmision recall on my car, dealer will be updating the dme or ECM, .... The computer firmware.
Ok, so far as I have read, if your car is on FW1, and built before March 2007, then you will need a Vista DRL harness to have halos as DRL?
Am I correct?
If dealer updates the computer, do I still need the Vista Harness?
I put this in the coding section, as this is a when to code, and not to code question.
Thx in advance for your input.
