- Ultrasonic sensors (front, rear, and side bumpers)
3. **NO PPF ON CAMERA LENSES**: The front camera in the radiator grille and the rearview camera in the trunk lid must remain completely unobstructed .
4. **NO METALLIC FILMS**: Metallic films can interfere with radar signals from the corner sensors.
**System Limits**: The function of the radar sensors may be restricted if sensors are covered (by labels, films, or license-plate carriers), dirty, iced-up, or if there is damage after improper paint work in the sensor area .
**If Your Gran Coupe Has Been in an Accident**: Sensors may become misaligned. Take your vehicle to an authorised BMW dealer to verify sensor alignment. A misaligned sensor can result in ADAS systems not operating to specification .
## 🛡️ WHY GRAN COUPE DEMANDS SPECIALIST PPF
### The BMW Paint Reality
BMW's premium paint finishes, especially on dark colours like Black Sapphire and Carbon Black, reveal every imperfection. The glossy finish that makes your Gran Coupe stand out is constantly exposed to threats on Indian roads – stray pebbles, road debris, construction dust, and swirl marks from improper washing .
**Real Owner Practice**: A BMW 2 Series Gran Coupe owner documented their protection strategy, confirming that PPF is standard practice among discerning BMW owners for the 2 Series Gran Coupe .
### The Value of PPF for Your Gran Coupe
A professionally applied paint protection film (PPF) is a must-have premium armour for your Gran Coupe. This transparent, thermoplastic polyurethane film acts as a self-healing barrier against scratches, stone chips, and other minor abrasions. It absorbs the impact, protecting the original paint beneath .
**Benefits of PPF for Gran Coupe**:
- **Preserves resale value**: Protects the integrity and depth of your BMW's paintwork
- **Simplifies maintenance**: Surfaces covered with PPF resist stains from dirt, bird droppings, and industrial fallout
- **Self-healing**: Minor scratches disappear with heat exposure
- **Invisible protection**: High-quality films maintain optical clarity
