Description
OEM DRL LED Control Module — Mercedes A-Class (W176) & CLA (C117) Replacement
This is the direct OEM replacement for the A2189009303 / A1668203589 DRL (Daytime Running Light) LED control module. It is specifically designed for the Mercedes-Benz A-Class (W176) and CLA-Class (C117 / X117) from 2013 to 2016 equipped with factory Xenon headlights (Pre-Facelift).
It restores reliable operation to your factory DRL and turn signal indicator system. If your Daytime Running Lights fail to turn on, flicker, or your front indicator has stopped working, this control module is the most common cause.
CRITICAL FITMENT WARNING: This module is for the A-Class W176 and CLA C117 only.
While this module shares the exact same part number (A2189009303) and physical appearance as the module used in the GLA (W156), they are internally different and not interchangeable. Installing a GLA module into an A-Class will result in partial or failed DRL function. Please ensure you are ordering for the A-Class W176 or CLA C117.
SCN Coding Required: Please note that this module is not plug-and-play. After installation, the module must be programmed. This can be done by a Mercedes dealer or an independent mechanic or auto electrician with a scan tool.
1 x Module unit. Fits either Left or Right side.

Frequently Asked Questions
Frequently Asked Questions
What vehicles does this module fit?
This specific module fits the Mercedes-Benz A-Class (W176) and CLA-Class (C117 / X117) from 2013 to 2016 equipped with factory Xenon headlights (Pre-Facelift models).
I have a GLA W156. Can I use this module?
No. Even though the GLA W156 uses a module with the exact same part number (A2189009303) and physical appearance, the internal electronics are different. Installing this A-Class module into a GLA will result in partial or failed DRL function. You must order the specific GLA W156 variant.
How do I know if my DRL module has failed?
The DRL failing to turn on, flickering, or the front turn signal indicator stopping working are the most common symptoms. Water ingress into the headlight housing is the leading cause of failure.
Do I need to program or code this module after installation?
Yes. SCN coding is required. The module must be programmed using the unique 11-digit code printed on a sticker inside your headlamp housing. Without this coding, the DRL will not function correctly. This coding can be performed by a Mercedes dealership or an independent specialist with Xentry diagnostic equipment.
