Repair boards for restoring the operation of rear LED lights of BMW X3 F25 (2011–2016 model years). The kit consists of 4 identical boards intended for replacing all segments of the rear lighting — two on the tailgate and two on the body. This is a universal solution that fits all four parts of the light, simplifying the repair process and parts procurement.

Analog of the original Valeo B003809.2 board, but with a significantly improved and optimized circuit. Our board features increased durability, energy efficiency, and stable operation. Unlike cheap Chinese analogs, it does not cause radio interference in the FM band and does not require modifications during installation.

The board is located on the outside of the light, making replacement extremely simple. You can perform the repair yourself without visiting a service center. For clarity, we have prepared a video tutorial on removal and installation:

Why do the rear LED lights of BMW X3 F25 fail? Over time (usually after 5–8 years of operation), the sections of the side marker lights stop working. The cause is the factory Valeo control board, which cannot withstand temperature fluctuations and loads. Dealers offer only full light replacement: a new inner light costs about 200 EUR, an outer one — 250 EUR. Buying used lights is a temporary solution, as the problem may recur. The LEDs themselves are practically eternal; the issue lies solely in the control electronics.

How to replace? To remove the old board, carefully use pliers to remove part of the factory-molded plastic (location shown in the photo), but do not cut it completely so that the new board remains securely fixed. Then, from the opposite side, pull and remove the old board at an angle. Installation of the new board is performed in reverse order. The entire process takes 20–30 minutes per light.

Cooling radiator	Aluminum, with thermal paste	Absent
Energy efficiency	Optimized circuit	Basic circuit, overheating
FM band interference	None	Often present
Service life	Long-lasting, designed for years	Short, often fails

Which BMW model and production years are these repair boards intended for?

This set of 4 boards is designed to restore the rear LED lights of BMW X3 F25 vehicles produced between 2011 and 2016. It is also compatible with the BMW X4 F26 model.

How many boards are in the set and why exactly 4?

The set includes 4 identical boards. This is a universal solution because the rear lights of the BMW X3 F25 consist of four segments: two on the tailgate and two on the body. The set is sufficient to replace all faulty control boards in the lighting system.

How are these boards better than cheap Chinese alternatives?

Our boards have several advantages: standard (original) thickness for a tight fit, an aluminum radiator on thermal paste for effective cooling, an optimized energy-efficient circuit, no radio interference in the FM band, and an increased service life thanks to high-quality components.

Can I install the boards myself without going to a service center?

Yes, the installation is designed for DIY repair. The board is located on the outside of the light, and the replacement process is shown in detail in the provided video instruction. The whole process takes about 20-30 minutes per light.

What is the lifespan of the LEDs and why do the lights stop working?

The LEDs themselves last a very long time. The cause of light failure is the original Valeo control board, which over time (usually after 5-8 years) cannot withstand temperature fluctuations and loads. Our boards solve this exact problem, restoring the operation of the LEDs.

What delivery methods are available in Latvia, Lithuania, and Estonia?

We deliver to Latvia, Lithuania, and Estonia via the Omniva parcel machine network (from 3 to 7 EUR) or by Omniva courier service (from 8 to 12 EUR). Self-pickup in Riga is also available for free.

How can I pay for the order?

Various payment methods are available: directly via SEB, LHV, Swedbank, Citadele, Luminor internet banking; credit/debit cards; via Apple Pay and PayPal; as well as by bank transfer based on an invoice.

Is there a warranty on the repair boards?

Yes, all boards come with a 12-month warranty, confirming their durability and quality of manufacture.

What should I do if only one segment of the light has stopped working?

The problem is usually with one specific board. However, considering the age of the car and the same operating conditions, we recommend purchasing a full set of 4 boards. This will allow you to replace all vulnerable control units at once, preventing repeated repairs in the near future.

Are the boards an exact copy of the original Valeo B003809.2?

Our boards are an analog (replacement) for the original Valeo B003809.2 board. They completely replicate the original connectors and mounting points, but have an improved and optimized electronic circuit, making them more reliable and durable compared to the original.
