3D0907391B / 89035113 Valeo Xenon Ballast VW Audi Volvo BMW – OEM Used & Tested

Description

This VW lighting control module is an original OEM component. The primary OEM number is 3D0907391B, with alternative reference 89035113 also shown on the unit. It is a genuine used unit, removed from a running vehicle and tested before listing, and is offered as a direct original (OEM) replacement rather than an aftermarket copy.

It manages the xenon or adaptive headlight functions, including beam leveling and cornering light operation. Because it is the original factory part, it fits, connects and communicates exactly like the unit that left the production line, so no changes to the wiring or the surrounding parts are needed. Fitting a matching original unit restores correct operation.

Common signs of a faulty unit include adaptive-lighting warning messages, headlights that no longer swivel in corners, incorrect beam leveling, or a headlight stuck in a fixed position. Problems like these often start intermittently and then become permanent, and a diagnostic scan will usually store related fault codes pointing to this unit. Replacing it with a tested original such as this one clears faults caused by the part itself.

This is a used original part, removed from a running vehicle and tested before sale. Please match 3D0907391B exactly against the number on your existing unit before ordering, as several similar units are used across the range and are not all interchangeable. Professional installation is recommended, and coding, programming or adaptation to the vehicle may be required after fitting depending on the equipment and configuration.
