Polo LED headlight DRL issue

Post by grahams »

I have a Polo 6C 2016 which was imported from Japan. It has factory LED headlights.

Polo 6C
Model year G
Highline
5 doors
1.2 TSI engine
66KW
DSG-7
LED headlights
Power folding mirrors
Automatic headlights
Heated seats
Discover Media + DAB
ACC + city brake assist
Climatronic

When I got the car there were no DRL's activated. JDM car's come with a Clarion infotainment system which has been successfully replaced with a discover media system.

Unfortunately I cannot find a full backup of a UK car with LED headlights and DRL. The closest I can find is a European car with very similar spec forums.ross-tech.com/index.php?threads/13921/ this is a post by @iichel
I have done a cross-check against this car and found a number of differences related to:

Light configuration
Leuchte2SL VLB22
Leuchte3SL VRB36
Leuchte4TFL LB43
Leuchte5 TFL RB6

Based on another post I've seen there is some confusion about which of these is the DRL.

Long coding differences relate to the steering wheel side, traffic side and MHz of the key.
