Question 1

What does the error message "traction control failure" mean on a BMW R 1200 GS Adventure?

Accepted Answer

Your BMW R 1200 GS Adventure has two traction control systems:

ASC (Automatic Stability Control) - standard system that detects instability on the rear wheel and automatically reduces engine torque.
DTC (Dynamic Traction Control) - available as an option through Pro riding modes, for more refined regulation.

If you receive a message indicating that traction control has failed, it can mean several things:

Flashing light while driving - The system normally intervenes to correct a loss of grip (a common situation during sudden acceleration on wet surfaces). This is normal operation.
Automatic test at startup - The ABS and ASC perform a self-diagnostic at startup. Wait a few seconds, the message usually disappears.
System manually disabled - Check the left switch. You may have intentionally turned off the system.
Detected fault - If the message persists while driving or the light stays on continuously, an electronic diagnosis is necessary. Consult a BMW Motorrad dealer.

The exact message displayed on your dashboard will help you identify the specific problem. The ASC and DTC systems are fully electronic and controlled by the motorcycle's computer - only a professional diagnosis can confirm a real malfunction.

Question 2

How to open the trunk of the BMW 435i xDrive Gran Coupe 2016?

Accepted Answer

The trunk (tailgate) of the BMW 435i xDrive Gran Coupe 2016 can be opened in several ways:

Using the remote key

Press the trunk open button on your key fob for about 1 second. The tailgate will open automatically.

From inside the vehicle

Use the trunk release button located in the driver's compartment (usually at the pedal level or on the door). Press it to open the tailgate.

Press directly on the button located on the tailgate (outside, usually in the center, near the handle). After unlocking the vehicle, this will open the trunk.

Comfort Access (keyless opening)

If your BMW is equipped with the Comfort Access system, you can open the trunk by placing your foot under the rear bumper, in the center of the vehicle, and then moving it slightly forward. The sensor will detect the movement and automatically open the tailgate.

Manual opening

In case of an electrical problem, after manually unlocking the vehicle, you can gently lift the tailgate by hand to open it.

Important: The tailgate opens upwards. Ensure you have sufficient space above and around the vehicle to avoid any damage to the trunk, roof, or nearby objects.

Question 4

What should I do if the convertible roof does not open or close?

Accepted Answer

If the convertible roof of your BMW 328i does not open or close properly, here are the points to check:

Preliminary Checks

Electrical System Status - Ensure that the battery is sufficiently charged. A weak electrical system can prevent the roof motor from functioning properly.
Safety Lock - Check that the vehicle is completely stopped and that the handbrake is engaged. Most convertible roofs have a safety lock that prevents operation while driving.
Extreme Positions - Try holding the roof control button pressed for a few seconds longer than usual. Sometimes, the system needs to travel the entire range to reset, especially if it has partially jammed.

Actions to Take

Restarting the System - Turn off the engine completely, wait 30 seconds, then restart. This may reset the roof control circuits.
Inspecting the Mechanism - Visually check that nothing is blocking the roof closure (fabric, debris, frost). Clean the tracks and joints if they are visibly obstructed.
Fuses and Relays - Refer to the wiring diagram in your manual to locate the fuses dedicated to the roof system. A blown fuse may be the simple cause of the malfunction.

If the Problem Persists

If after these checks the roof still does not work, it is likely that there is a mechanical defect (blown motor, broken position sensor) or a more serious electrical issue. Consult a BMW dealer or a specialized mechanic for a complete diagnosis and repair.

Question 5

How to reset the service overdue message after an engine oil change?

Accepted Answer

If you have performed the engine oil change yourself and BMW Nantes refuses to clear the "Service overdue" message, please note that this message can generally only be reset by an authorized BMW dealer via the diagnostic system.

However, a few points to clarify:

Warranty and maintenance: according to the manual, proof of maintenance work performed is a prerequisite for warranty coverage. Performing the oil change yourself with BMW oil is generally not recognized without documented proof.
Service message: the system displays two different alerts - "Service due" (in yellow) and then "Service overdue" when the deadline has passed. These messages are related to mileage and date (service every 10,000 km or once a year).
Oil check: you can check the oil level via the "My vehicle" menu on the TFT screen of the dashboard to confirm that the operation has been completed.

To have this message cleared permanently, you will need to contact another BMW dealer or an authorized BMW workshop specialized in diagnostics. Bring your BMW oil purchase receipt as proof.

Question 6

Why is the anti-theft alarm (DWA) no longer producing sound, even though the turn signals are activating?

Accepted Answer

If the DWA anti-theft alarm is activated (the turn signals are working) but is no longer producing a beep sound, several causes are possible:

Checks to perform

Status of the DWA battery - Check the TFT screen on the dashboard. If the message "DWA battery capacity low" or "DWA battery discharged" appears, the alarm system's battery is depleted. It can no longer emit the sound alert, even if the turn signals continue to function. Visit a specialized BMW workshop to replace this battery.
Failure of the DWA system - If the screen displays "DWA malfunction", the alarm system has a hardware anomaly. The sound alert is not functioning properly. A diagnosis at a BMW workshop is necessary.
Sound alert - The sound alert is located at the left stalk. It may have an electrical or mechanical defect without affecting the rest of the DWA system (the turn signals remain operational).

Recommendation: First, check the error messages displayed on the TFT screen. If no message appears but the sound continues to be absent, an electronic diagnosis via a BMW workshop will help pinpoint the fault (DWA battery, sound alert, or electronics).

Question 7

Accepted Answer

To activate the alarm on your BMW R 1250 GS Adventure (2019), follow the steps below:

Make sure the motorcycle is in the "OFF" position: the ignition key must be in the off position.
Turn the ignition to the "ON" position without starting the engine.
Use the remote control: press the button dedicated to the alarm, usually identifiable by a padlock or alarm symbol.
Activation confirmation: you should hear a beep or see the lights flash, indicating that the alarm is activated.
Check the indicator light on the dashboard, which should light up to confirm activation.

To deactivate the alarm, press the same button on the remote control again. If the alarm does not activate, check the remote control battery or contact a BMW professional for assistance.

Question 8

How to install a roof box on a BMW i3?

Accepted Answer

Installing a roof box on your BMW i3 requires a professional approach. BMW strongly recommends that any modifications and work on the vehicle be carried out by an authorized BMW i service center or by a qualified service with personnel trained to BMW i specifications. This recommendation is particularly important as the BMW i3 has a unique ultra-lightweight carbon fiber body structure and a high-voltage system that require specialized expertise.

Before considering installation, check that the roof box you wish to install is explicitly compatible with your BMW i3. Roof boxes approved for the BMW i3 are generally designed to work with roof bars that have a maximum width of 60 mm (adapters available for bars up to 94 mm) and a maximum distance between the bars of 85 cm. Refer to the roof box documentation to confirm its compatibility with your specific model.

If you already have compatible roof bars, the box attaches without specialized tools and installation takes about 15 minutes. However, if you need to install the roof bars yourself, we recommend entrusting this first step to an authorized BMW professional, who will ensure that the fittings are properly adapted to the vehicle's carbon structure.

The load capacity depends on the chosen box model but generally remains between 75 and 90 kg. It is crucial not to exceed the maximum prescribed load, as this could affect the performance of the Dynamic Stability Control (DSC) system and the range of your battery. Driving with a roof load alters the vehicle's behavior and energy consumption.

To obtain the accessories and installations suitable for your BMW i3, contact your authorized BMW i service center. Qualified personnel will advise you on the available options for your model, carry out installations in accordance with BMW specifications, and ensure that there is no safety risk related to the high-voltage system.

Question 9

How to turn on the fog lights on a BMW R 1200 GS Adventure (2017)?

Accepted Answer

On your BMW R 1200 GS Adventure (2017), the fog lights are referred to as additional LED headlights. To turn them on, you must first start the engine and activate the low beam headlights (a prerequisite - the additional headlights only work if the low beam is active). Then, press the button 1 located on the left handlebar control (above the headlight control block). A warning light for the additional headlights will illuminate on the dashboard to confirm their activation.

Be aware that these additional headlights are approved as fog lights and should only be used when weather conditions are poor. Follow the traffic regulations in your country, which precisely define when it is legal to use fog lights. In particular, do not leave them on at all times or in low light without fog.

To turn off the additional headlights, press the same button 1 again. The warning light will turn off, confirming the shutdown of these headlights. They will also automatically turn off when the ignition is switched off, after a short moment.
