2 pieces BMW X3 F25 Valeo B003809.2 boards (analog) for restoring rear LED lights

Repair boards for restoring the function of the rear LED taillights on BMW X3 F25 vehicles. The boards are universal and fit all 4 segments of the rear lights (two on the tailgate and two on the body). This is the optimal solution for fixing the common problem of malfunctioning parking lights on BMW X3 F25 models from 2011-2016.

The offered boards are an analog of the original Valeo B003809.2 board, but with significant improvements. We offer a more optimized and durable circuit that addresses key flaws of the factory part and cheap alternatives.

Why do the parking lights fail?

Over time, the parking light strips on the BMW X3 F25 stop working due to the failure of the standard control board from manufacturer Valeo. Official dealer service centers typically offer only the expensive replacement of the entire taillight unit: a new inner light costs around 200 EUR, an outer one – 250 EUR. Buying used lights is only a temporary solution, as the problem may recur. At the same time, the LEDs themselves in the lights have a practically unlimited lifespan.

Advantages of our repair boards

Our boards offer a cost-effective and reliable alternative:

• Improved design: Compared to cheap Chinese analogs, our boards have standard thickness and are equipped with an aluminum cooling radiator attached with thermal paste. This ensures efficient heat dissipation and extends the lifespan of electronic components.
• No interference: The boards do not cause interference when listening to FM radio, unlike many budget alternatives.
• Perfect fit: Due to the correct dimensions, the boards fit snugly into the standard mounting location, without wobbling or requiring modification.
• Energy efficiency: The circuit has been redesigned for better energy efficiency, which improves reliability.

Board replacement process

Board replacement is a procedure that can be performed independently, without visiting a service center. The boards are located on the outside of the light, making them easily accessible.

Replacement instructions:

1. Carefully remove the rear taillight (video tutorials for removal are easily found online).
2. To remove the old board, you need to partially bite/break off part of the factory-molded plastic (shown in the photo) with pliers, but do not cut it off completely so that the new board retains a tight fit.
3. From the opposite side of this plastic, slightly angled, pull and remove the old board.
4. Install the new board in reverse order.
