Almost three years ago my dealer refused to enable my DRLs citing a lack of resources.
Today I turned them on myself.
Laptop Windows 7 computer
A high quality OBD II scanner (OBDLink MX - bluetooth version)
Forscan program version 2.3.0
Free 2 month license key for Forscan special features
I had previously used a relay to activate the front parking lamps anytime the car was on. They are not very bright and didn't really do the job. The circuit is still there but I removed the fuse.
