BMW X3 F25 rear LED lights restoration board Valeo B003809.2 (analogue)

The Valeo B003809.2 rear LED taillight repair board for the BMW X3 F25 is a professional solution to the common problem of non-working parking lights. This malfunction is typical for BMW X3 (F25 model) vehicles manufactured between 2011 and 2016. Usually, the cause is the failure of the standard LED driver control board manufactured by Valeo. The official dealer service in such cases offers only a complete taillight replacement, which is an extremely costly procedure. The price of a new inner taillight is about 200 euros, and an outer one is 250 euros. The rear lighting consists of four segments: two on the body and two on the trunk lid, which can sum up to replacing all four elements.

Our repair kit offers an economical and reliable alternative — replacing the failed factory (OEM) board with our Valeo B003809.2 analog. Our board is an improved version with an optimized and more durable electrical circuit. It does not cause interference in the FM radio band, unlike many cheap Chinese analogs available, for example, on Aliexpress.

Key advantages of our repair kit:

• Savings: The cost of repairing one board is only a fraction of the price of a new taillight.
• Versatility: The same board fits all four segments of the rear taillights (left/right, inner/outer).
• High quality: The board has a full aluminum radiator glued with thermal paste, ensuring effective heat dissipation and significantly extending component lifespan.
• Easy installation: The boards are located on the outer side of the taillight, making replacement accessible even for DIY repair. Detailed video instructions for taillight removal are available online.

Detailed replacement instructions:

1. To remove the old board, carefully bite off or break off part of the factory-molded plastic (the location is indicated by a white arrow in the image). It is important not to cut it off completely so that the new board retains a tight fit in the mounting location.
2. From the opposite side of this plastic, at an angle, pull and remove the old board.
3. Install the new board in reverse order.

The new board is successfully installed in place:
