Can the hidden one-touch window lift function of the old Citroen C-Quatre be modified?

The hidden one-touch window lift function of the old Citroen C-Quatre can be modified. Here is some relevant information about the Citroen C-Quatre: Exterior: The Dongfeng Citroen C-Quatre features a streamlined body with smooth and full curves, achieving an excellent drag coefficient of 0.31. This not only gives it a perfect styling but also effectively reduces wind noise during driving, as well as lowers fuel consumption and harmful emissions. The ingeniously designed rear taillights blend seamlessly with the rear of the car, outlining smooth rear lines. They also cleverly combine with the side rear windows to form the distinctive Citroen double chevron logo, creating a dynamic look. Interior Suggestions: Equipping your car with seat covers, cushions, seat sets, floor mats, and floor liners is a priority for many car owners. Typically, car seats are placed on a carpet-like material that is difficult to clean once dirt or stains get on it. Installing floor liners makes cleaning much easier. Floor liners generally come in two types: hand-sewn and pre-formed. Well-crafted hand-sewn liners can effectively prevent dust and dirt from seeping into the carpet, though their waterproofing capability is somewhat limited. Various cotton lumbar supports, wool seat cushions, and faux fur floor mats suitable for autumn and winter use are already available on the market.
I previously drove an older Citroen C-Quatre, and this hidden one-touch window lift feature can indeed be modified. You need to connect a diagnostic tool to the OBD port and access the BCM module, then enable the lock-and-close window option in the configuration menu. The easiest way is to visit a professional modification shop—they can complete it in just 5 minutes using the factory DiagBox software, costing around a hundred yuan. After flashing, remember to test the anti-pinch function, as some cars require resetting the window memory. Once modified, it’s super practical—no more running back to the car to close windows on rainy days; just hold the remote lock button to auto-close the windows. Older car wiring is prone to poor contact, so it’s best to check for aging issues in the driver’s side switch wiring first.
