Thanks again for your reply.
If I decide to take the car to the dealer, and have them fix the headlights only DRL. Will this reset the other tweaks I have done. Like fogs as DRL, no teardrop rear wiper, among others?
(Because I think it was illegal to have front only DRLs in Norway up until last month, and the dealers had to change the codes for all cars delivered). I have lately seen both VW Transporters, and other VW's that have this setting.
I'm not sure I understood what you said about the RLS coding. You mean this is done in another byte still to be properly documented?
I understand the Freeze Frame problem. I would really like to have accurate readings. But I'm not sure I would have them at the expence of the quick auto-scan.
