Hi everyone,
I have 2012 F20 116i Sport Line and same problem.
The rear light system of 1 series is different from X3. When you remove the headlamp in X3, we can access the Valeo chip. However, in our laminates, the system is completely closed and inaccessible. The only way to get to the motherboard is to remove the window from the rear lamp and detach it from the main unit. In this way, the problem is solved if we can directly connect the LED.
But this method may be troublesome. Because the water from the outside and the air will enter the rear lamps.
There seems to be no choice but to change the rear lamp.
By.
