Ok, I possibly have a solution for the problem but can't code it myself because I'm using Car Scanner and acces is blocked by Skod. It could work on Obd11 if anyone wish to try. I'm looking for someone with Obd11 to try myself. If your left-side illumination is completely dead or dropping low as soon as you hit the slip road—even before you accelerate past 68 mph—this points to a different system interaction. On the Škoda Superb Mk3 FL, your headlights continuously talk to the front camera (Module A5) and the factory navigation system. The moment the GPS detects you are merging onto a motorway slip road, it preemptively commands the Matrix modules to shift from City/Country Light profiles into Motorway Prep Mode, instantly dropping or masking the left side to avoid blinding truck drivers or high-up road signs. If your dashboard says "Left-Hand Traffic" but the car cuts the left side on the slip road, the car’s GPS tracking module is processing the road geometry backward. It fundamentally believes you are merging onto a Continental European motorway (Right-Hand Traffic) and is trying to protect what it thinks is an opposing lane on your left. The root cause can be fixed with specific byte configurations. The Fix: Invert the LHD/RHD Navigation Logic When using Car Scanner Pro, you must force the Front Sensor Camera (A5) and Multifunction Headlight Gateway (4B) to stop letting the navigation map invert your traffic orientation. Step 1: Fix Module A5 (Front Sensor / Driver Assist Camera) This camera handles the actual lane classification and reads slip road geometry. ◦ Open Coding & Service → Front Sensors (A5) → Long Coding (Raw).Go to Byte 0 (the very first pair of numbers).If your app shows bits, look for the option labeled Country_variant or System_Selection.If it is currently set to hexadecimal 01 (Europe / Left-Hand Drive), change it to 02 (UK / Right-Hand Drive).Note: If it is already on 02, the navigation link is corrupted. Check Bit 4 or 5 inside this byte for a toggle named Navigation_Adaptive_Light_Assist and turn it Off. Step 2: Fix Module 4B (Multifunction Module) The headlight master needs to stop responding to the navigation-based road classification. 1. Open Coding & Service → Multifunction Module (4B) → Long Coding (Raw).Navigate to Byte 5.Look for the individual bit labeled Navigation_Light_Functions or Intersection_Light_via_GPS.Uncheck this bit (change its value from 1 to 0).Why this works: Disabling this stops the navigation system from overriding your headlights based on GPS coordinates. The car will rely purely on what the physical camera sees in front of you on the slip road, preventing it from incorrectly dimming the left curb. ─── Step 3: Hard Reset to Lock in the Left-Hand Beam After applying these raw changes, you must clear the memory buffers: Turn the ignition off, lock the car, and wait 2 full minutes for the CAN-bus modules to enter sleep mode.Turn the car back on, go to the infotainment screen, and navigate to Vehicle → Settings → Lights.Toggle the traffic setting to Right-Hand Traffic, wait 5 seconds, and then flip it firmly back to Left-Hand Traffic.Press and hold your infotainment power button for 10 seconds until the screen reboots.This severs the incorrect GPS calculation, forcing the Matrix headlights to project a wide, full beam down the left slip road and curb exactly as required for UK motorways
