Disabling daytime running lights (Eurolight) on Nissan Qashqai J10: 3 proven methods

Daytime running lights (DRL), or as they are often called by car owners - Eurolight, have become a mandatory safety element in modern cars. However, on Nissan Qashqai J10 (2007–2013) their work does not always suit drivers: someone complains about generator overload, others - on incorrect work with dimensions, while others simply want to return to the classic lighting scheme. In this article we will analyze all legal ways to disable DRL on Qashqai J10 without harm to electronics, including nuances for restyled versions (2010–2013) and models with xenon.

Before proceeding with modifications, please note: disabling the DRLs may affect passing a technical inspection in some countries (for example, in the EU this is a traffic violation). In Russia, starting from 2020, the requirements for DRLs have been relaxed, but the final decision remains with the inspector. If you are determined to get rid of Eurolight, choose the method that matches your version Qashqai J10 and level of training.

Why do Qashqai J10 owners want to turn off the Eurolight?

On forums and in service centers they highlight 5 main reasons, by which drivers are looking for ways to deactivate DRL:

• 🔋 Increased load on the generator: DRLs consume up to 20–30 W, which leads to battery undercharge, especially in winter.
• 💡 Conflict with dimensions: On some versions of the Qashqai J10, the DRLs do not turn off when the lights are turned on, creating visual dissonance.
• 🔧 Lamp burnout: Stock DRL lamps (eg W5W or T10) often burn out due to overheating, and their replacement costs 500–1500 rubles per pair.
• 🚨 False positive errors: Control unit (BCM) may give an error B2605 (DRL circuit malfunction) even with working lamps.
• 🎨 Aesthetic preferences: Many owners prefer the classic look with lights or PTF on instead of bright white DRLs.

It's interesting that on restyled Qashqai J10 (2010–2013) problems with DRLs are less common due to improved firmware BCM. But on pre-restyle versions (2007–2009), Eurolight often works incorrect, for example, does not turn off when the low beam is turned on. This is due to the logic features of the lighting control unit.

Method 1: Disabling DRL via diagnostic connector (OBD-II)

The most safe and reversible method - deactivation of Eurolight through diagnostic equipment. For this you will need:

• 🔌 Adapter ELM327 (version 1.5) or VCDS for Nissan.
• 💻 Laptop/smartphone with the program Nissan Consult III+, NDS II or Forscan (for advanced users).
• 🔧 Basic skills in working with diagnostic software.

Step by step instructions:

1. Connect the adapter to the connector OBD-II (located under the steering wheel, to the left of the brake pedal).
2. Launch the program and select a model Qashqai J10 (indicate the exact year of manufacture!).
3. Go to section BCM (Body Control Module) → Configuration.
4. Find the parameter Daytime Running Lights (DRL) and set the value Disabled.
5. Save changes and reboot BCM (turn off/on the ignition).

⚠️ Attention: On some versions Qashqai J10 after disabling the DRL through diagnostics they can Dimensions turn on independently when starting the engine. It has to do with logic BCM, which interprets the absence of DRLs as a malfunction. This can be solved by installing a resistor (see Method 3) or adjusting the firmware.

What to do if the program does not see BCM?

If the diagnostic software does not detect the body control module, check:

1. The quality of the connection between the adapter and the connector (try a different USB cable).

2. Firmware version ELM327 (must be at least 1.5).

3. Availability of power on the 16th OBD-II pin (check with a multimeter).

4. No errors in the BCM itself (for example, code U1000 — loss of communication via the CAN bus).

Method 2: Flashing the control unit (BCM)

If software disabling did not help or you want completely remove the DRL function from the car logic, flashing will be required BCM. This method irreversible without original firmware, therefore suitable only for experienced users.

Algorithm of actions:

1. Read current firmware BCM with the help Nissan Consult III+ or KTAG.
2. Download modified firmware (for example, from TunerPro or WinOLS) with DRLs disabled. For Qashqai J10 current versions:
   • BCM_28160-4M000 (pre-restyle, 2007–2009)
   • BCM_28160-4M010 (restyle, 2010–2013)

Write the new firmware to BCM (necessarily with backup power!).

Reset errors and test lighting operation.

BCM version	Supported years	Risks of flashing	Cost of service (service)
28160-4M000	2007–2009	Possible loss of central locking settings	3 000–5 000 ₽
28160-4M010	2010–2013	The window lift adaptation may be reset	4 000–6 000 ₽
28160-4M020	2013 (late batches)	Immobilizer activation required after firmware update	5 000–8 000 ₽

⚠️ Attention: Incorrect firmware BCM may lead to loss of communication with the immobilizer or central locking failure. If you are not confident in your skills, contact a service with equipment for Nissan (For example, Launch X431 or Autel MaxiSYS).

Method 3: Mechanical shutdown of DRL (for experienced)

If software methods are not suitable, you can physically turn off power daytime running lights. This method requires intervention in the electrical wiring, so it is only suitable for those who understand auto electrics.

Disable options:

• 🔌 Disconnecting the DRL connector: Locate the fuse box under the hood (next to the battery) and remove the fuse F38 (10A) — he is responsible for powering the DRL. Minus: on some versions this also disables license plate illumination.
• 🔧 Resistor installation: If after turning off the DRL, an error light comes on on the dashboard, connect a resistor in parallel with the lamps 6.8 Ohm (power 50 W). This simulates the load for BCM.
• 🔄 Switching to dimensions: On some Qashqai J10 you can redirect the DRL power to the side lights by changing the pinout in the relay block (relay K30).

⚠️ Attention: When DRL is mechanically switched off Be sure to check the low beam operation. On some Qashqai J10 after removing the fuse F38 stops working correctly automatic headlights (function Auto Light).

Common mistakes and how to avoid them

When the Eurolight is turned off Nissan Qashqai J10 owners often face typical problems:

• ⚡ Error B2605 (DRL circuit): Occurs after a mechanical shutdown. The solution is to install a resistor or reset errors via Nissan Consult.
• 🔦 Spontaneous activation of dimensions: Related to logic BCM, which interprets the absence of DRLs as a malfunction. The solution is to reflash the block.
• 🚗 Automatic headlights don't work: After turning off the DRL, the light sensor setting may be lost. The solution is to calibrate the sensor through diagnostics.
• 🔋 Low battery: If the battery drains quickly after turning off the DRLs, check leakage current multimeter (norm - up to 50 mA).

On restyled Qashqai J10 (2010–2013) the problem with conflict between DRL and PTF. For example, when the fog lights are turned on, the Euro light does not go out, which is contrary to traffic regulations. In this case, only flashing will help BCM or installing an additional relay.

Legal nuances: is it possible to drive without DRLs?

In Russia, starting from 2020, requirements for daytime running lights not so strict, like in Europe. According to clause 19.5 of the Russian Traffic Regulations, during daylight hours it is enough to use:

• 💡 Low beam headlights;
• 🌥️ Fog lights (only together with dimensions);
• 🔆 Daytime running lights (if they are provided for by the design).

Thus, lack of DRL is not a violation, if you use low beam or PTF. However, the traffic police inspector may issue a warning if he considers that your car does not correspond to the factory configuration (for example, if the DRLs were turned off mechanically and the wires were simply cut).

In EU countries (e.g. Germany or France) driving without DRLs strictly prohibited and is punishable by a fine of up to 100 €. If you are planning trips abroad, it is better to return Eurolight or use led lamps with DRL/dimensions function.

FAQ: Answers to frequently asked questions

Is it possible to disable DRLs on a Qashqai J10 with xenon?

Yes, but there are nuances. On versions with xenon headlights (HID) DRLs are often implemented through Reduce voltage on low beam lamps ("half-light" mode). In this case, turning off the Eurolight may lead to constant operation of xenon at full power, which shortens the life of the lamps. We recommend using the software method (via Nissan Consult) or install resistors.

After turning off the DRL, the Check Engine light came on. What to do?

Error Check Engine is not related to the DRL - it indicates problems with the engine or transmission. However, if the dashboard shows light bulb icon (not "check"), this is a lighting error (e.g. B2605). Reset it through the diagnostic scanner or disconnect the battery for 10 minutes. If the error returns, check the DRL circuit for a short circuit.

How to return DRLs back after disconnecting?

The recovery method depends on the shutdown method:

• If the DRL was turned off through diagnostics, repeat the procedure and set the parameter Daytime Running Lights in Enabled.
• If you reflash BCM - you will need to return the original firmware (be sure to make a backup before making changes!).
• If it was disconnected mechanically, install the fuse back. F38 or connect the DRL connector.

Will there be more load on the generator after the DRL is turned off?

No, on the contrary - the load will decrease. DRLs consume about 20–30 W, and low beams consume 100–130 W (for halogen lamps). However, if you drive with the lights on instead of the DRLs, the difference in consumption will be minimal (the lights consume ~10 W). The main thing is to follow on-board voltage (normal 13.8–14.4 V when the engine is running).

Is it possible to turn off the DRL on only one headlight?

Technically possible, but not recommended. Asymmetrical lighting operation can confuse other drivers and lead to accidents. If you need to turn off the DRL on one side only (for example, due to a burnt out lamp), it is better to temporarily install LED lamp or a resistor to simulate a load.
