Exterior Design: The original sporty style of the 3 Series has been further retained. The polygonal double-kidney grille and the new Angel Eye headlights feature an additional recess in the middle below the headlights, with the bumper lines extending into the recess to connect with the headlights. From the side view, the new car remains very sleek, with the rear-wheel-drive configuration resulting in a long hood and short rear deck, complemented by a continuous waistline and the new Hofmeister kink. The rear of the car follows the family design, featuring L-shaped elongated taillights, a flat rear end, and dual single exhaust pipes. The new BMW 320/330 models adopt a dual-exhaust layout, with the 330 version also featuring a small carbon fiber spoiler on the trunk lid. 2.

Can a BMW 3 Series start without the key? This is a question I often get asked, as many cars nowadays come with high-tech features. Generally speaking, without the key inside the car, the engine indeed cannot be started. BMW's Comfort Access system relies on the key's radio frequency signal to authorize the starting process. The key must be inside the car or very close to the vehicle's range for the sensors to recognize and initiate the ignition command. If you forget the key or its battery dies, you might find the car completely unresponsive, leaving you with no choice but to use a spare key or seek professional assistance. A friend of mine once tried using the BMW ConnectedDrive App for remote start, but this usually requires prior setup and the key to be within Bluetooth range. To avoid awkward situations, it's advisable to develop a habit of checking your pockets or bag for the key and to familiarize yourself with your car model's specific configuration options.

What Causes the Brake Light on the Dashboard to Illuminate During Emergency Braking?

Emergency braking causing the dashboard brake light to illuminate may indicate issues with the car's brake discs, such as excessive wear, which affects the dashboard light. This indicator is mostly used to show the wear condition of the brake discs and is usually off. It could also be due to insufficient brake fluid triggering the fault light or a short circuit in the brake warning light circuit. Solutions: 1. Severely worn brake pads—when the car's brake pads reach their limit, an alarm will activate. Regularly inspect the tire brake pads; if they are significantly worn, replace them immediately. 2. During braking, brake fluid is compressed into the pipelines and brake calipers. Regularly check the brake fluid reservoir for low levels and top up the brake fluid promptly. 3. A circuit break may cause the dashboard light to alert. Use a multimeter to test the car's brake pad alarm circuit, brake fluid level alarm circuit, and handbrake switch circuit to check for any wiring issues.
