Bmw 740Ld Xdrive Daytime Running Light Modules

Bmw 740Ld Xdrive Daytime running light modules

Starting at $140.95, AutoBuffy carries 1 daytime running light modules from URO to fit your Bmw 740Ld Xdrive. The DRL module controls when and how your daytime running lights activate, regulating voltage and on/off logic. When it fails, your DRLs may stop working entirely, trigger warning lights, or behave erratically — a safety and legal concern in many states and provinces.

Signs your Bmw 740Ld Xdrive needs a new daytime running light module

  • DRL indicator light on the dashboard stays illuminated even after the fault is cleared
  • Daytime running lights do not turn on at all when the engine is running
  • DRLs flicker or cycle on and off randomly while driving at normal speeds
  • One DRL works normally while the other stays dark, despite the bulb testing good
  • DRLs remain on permanently and cannot be switched off, even when the ignition is off
  • Scan tool reports a DRL module fault code or a related body-control communication error

Which daytime running light module should you buy for your Bmw 740Ld Xdrive?

The most important decision is whether to buy an OEM-equivalent or an aftermarket module, and whether it needs to be programmed to your vehicle's network. Some Bmw 740Ld Xdrive applications use a standalone DRL module, while others integrate DRL logic into the body control module — confirm which applies before ordering.

OEM-Equivalent (Direct-Fit)
Best for
Owners who want guaranteed plug-and-play fitment with no calibration
What you get
Exact connector, mounting tabs, and voltage output matching original specs; typically requires no reprogramming
Aftermarket Performance Module
Best for
Owners upgrading to LED DRLs or wanting adjustable brightness/delay
What you get
Broader compatibility, selectable output modes, and sometimes built-in PWM dimming control
Remanufactured Module
Best for
Budget-conscious owners with a repairable core unit
What you get
Rebuilt OEM housing with replaced failed components; lower cost, comes with a core-charge refund
Integrated BCM/Module Assembly
Best for
Vehicles where DRL logic is embedded in the body control module
What you get
Full BCM assembly pre-loaded with DRL control logic; may require dealer or shop programming to VIN

Replacing the daytime running light module on a Bmw 740Ld Xdrive

Moderate⏱ 30 minutes – 1.5 hoursBasic socket and ratchet setFlathead and Phillips screwdriversMultimeter (for circuit testing)Trim removal tools (if module is behind a panel)OBD-II scan tool (to clear fault codes after install)

Locate the DRL module using your Bmw 740Ld Xdrive service diagram — it is typically mounted near the fuse box, headlight assembly, or behind a trim panel. Disconnect the battery, unplug the module connector, remove any retaining fasteners, and install the new unit in reverse order. Clear any stored fault codes with a scan tool after reconnecting the battery to confirm normal DRL operation.

Frequently asked questions

How much does it cost to replace daytime running light modules on a Bmw 740Ld Xdrive?
Parts start at $140.95 for a Bmw 740Ld Xdrive DRL module at AutoBuffy. Add an hour or two of shop labor if you're not doing it yourself. Total out-of-pocket cost varies depending on whether the module needs dealer programming, which can add to the overall job price.
Can I drive my Bmw 740Ld Xdrive with a failed daytime running light module?
Technically yes, but it is not advisable. DRLs are required by law in Canada and several U.S. states, and a failed module can disable them entirely. Beyond the legal risk, DRLs meaningfully improve your visibility to other drivers, particularly in dawn, dusk, and overcast conditions.
Will a new DRL module on my Bmw 740Ld Xdrive need to be programmed?
It depends on the design. Standalone DRL modules on many Bmw 740Ld Xdrive applications are plug-and-play and need no programming. However, if the DRL function is embedded in a body control module or uses a VIN-coded control unit, programming by a dealer or qualified shop with the right scan tool is required before it will function.
What causes a daytime running light module to fail on a Bmw 740Ld Xdrive?
The most common causes are voltage spikes from a failing alternator, water intrusion into the module housing, corrosion at the connector pins, and general heat fatigue over time. On high-mileage Bmw 740Ld Xdrive examples, relay contacts inside the module can also burn out from repeated cycling over years of use.
How do I know if the problem is the DRL module or just a burned-out bulb on my Bmw 740Ld Xdrive?
Test the bulb first — it is the cheaper and faster fix. If replacing the bulb does not restore DRL function, check for power and ground at the module connector with a multimeter. No output signal from the module with good power and ground present is a strong indicator the module itself has failed.
How long does a daytime running light module typically last on a Bmw 740Ld Xdrive?
Most DRL modules are designed to last the life of the vehicle under normal conditions. Premature failures are usually tied to environmental factors like road-salt corrosion, moisture intrusion, or electrical issues elsewhere in the system. Modules on vehicles in harsh climates or with charging-system problems tend to fail earlier than average.
