Volvo S40 Years To Avoid

Volvo S40 Years To Avoid – There is nothing particularly wrong with the S40, but it is common to find a 2nd generation Volvo S40 with problems such as worn rear brake calipers or engine mounts, as these are some of the problems it is likely to have. Discover the five most common problems you commonly encounter on the 2005 to 2012 Volvo S40 and how to fix them.

The fuel rail pressure sensor reads how much fuel pressure there is within the fuel lines. You may notice the engine stalling occasionally, such as when starting the engine or stalling when the fuel rail pressure sensor is bad. Increased fuel consumption may also occur and you may have to make more trips to the gas station than usual.

The fuel rail pressure sensor is located on the fuel rail at the front of the engine. You can test the sensor during idling, acceleration and loading with a scanner that can display fuel pressure. You can also test the sensor with a fuel gauge by connecting it to the fuel rail and driving the car. If the fuel pressure is good but the check engine light is on, there is a problem with the sensor and it needs to be replaced.

Engine mounts support the engine and prevent it from being bolted directly to the S40’s body. The engine mounts have two metal sections and one rubber section. The rubber section can crack or break and usually fails as the rubber wears over time. Lack of support from a faulty engine mount can cause engine vibrations to be felt in the passenger compartment.

An assistant can help troubleshoot engine mount problems on a 2005 to 2012 Volvo S40. With the car parked and the hood open, the assistant can look at the mounts and engine and check for a lot of movement when the engine is running. Have the driver put his foot on the brake and, with someone watching the engine from a safe position, observe how it behaves in drive and reverse. Excessive movement indicates that there is a problem with the motor mount.

You can also check the engine mounts for dry, rotted, cracked or damaged motor mounts. If the motor mount is damaged, replace it. We recommend replacing them all at once.

The headliner is known to lose adhesion to the headline material over time. This can cause problems if the roof of the 2005 to 2012 Volvo S40 falls and obstructs the driver’s view in the rearview mirror.

You can perform a professional roof repair and replace the roofing material. You can also try spray adhesive and hold the roof in place, or replace it yourself.

The caliper piston can become stuck, preventing the brake pads from pressing against the rotor and stopping the vehicle safely. This constant friction can cause a burning smell in the brakes and in some cases cause them to smoke. If the piston is frozen and cannot hold the pads, the rotor will rust. The car may also appear to pull to one side when braking if one of the brake calipers is defective.

The brake caliper of the S40 gen is a rotating type. This means you need a special tool to restore it. The piston can not only be bent with pliers, but must be rotated and pushed.

We recommend that you change the brake pads and rotors when you change the brake calipers. If you change the brakes on one side, we recommend that you change them on the other.

The axle CV joints have boots to keep them lubricated and prevent debris from entering. The CV joint allows the axle to rotate at the same speed as the wheel when turning. This creates a lot of friction, so grease is needed to prevent the joint from binding and to help dissipate heat. Sometimes the protective sleeve can tear and can introduce debris and cause binding, which makes a clicking noise and can spray axle grease onto parts under the car.

If the shaft protective sleeve is torn or damaged, replace the shaft. You can replace just the boot, but we recommend replacing the entire axle since the second boot will likely wear out sooner. Remember to align all four wheels after completing this repair.

The new Volvo S40 sets the standard in its class with an extremely high level of safety, both protection and prevention, and represents an evolution of the “You think and then you build” motto that began with the award-winning XC90 sports utility vehicle. vehicle.

It’s all part of Volvo’s Intelligent Vehicle Architecture (VIVA), a unique way of creating a car that combines everything from its crashworthiness to its dynamic styling and exciting driving characteristics. This is possible thanks to the numerous devices involved, including a very rigid body, a new front structure and the world’s first intelligent driver information system.

Safety systems are developed and tested at the Volvo Cars Safety Center, the most advanced facility of its kind in the world. Some forty full-scale tests were carried out to ensure that all components on board worked together, not to mention countless simulations of computer failures.

During the development of the new Volvo S40, the goal was to achieve first-class safety using a new way of thinking about how cars deform in a collision.

“Our goal of creating vehicles that are the safest in their class applies to all models, including the new Volvo S40,” says Ingrid Skogsmo, director of the Volvo Cars Safety Center.

In the event of a collision, the conditions for effective deformation are critical. Since the necessary deformation can be absorbed over a limited total distance, the various material properties must be fully exploited to absorb the greatest possible amount of incoming energy.

“It’s a difficult challenge, but we face it in a new way,” confirms Ingrid Skogsmo. “We call it Volvo’s intelligent vehicle architecture.”

The front body structure of the new Volvo S40 is divided into several zones, each of which has its own task in the deformation process. The outer zones are responsible for most of the deformation. The closer the collision forces are to the passenger compartment, the less the materials will deform. The intention is for the passenger compartment to remain intact in most collisions.

To give each zone the relevant properties, different types of steel are used in different areas. Four different types of steel are used. In addition to the usual steel for the body, three different grades of high-strength steel are used: high-strength steel, extra-high-strength steel and ultra-high-strength steel.

What’s also unique is that the new S40 went through a series of computer-simulated frontal crash tests without the engine installed. The machines are then designed to fit into the empty space left after the simulated crash test. In a real accident, the engine would deflect 5.9 inches before hitting the bulkhead.

The front bumper has an extremely rigid cross member made of boron steel. The fastenings of the longitudinal parts of the body are designed in the form of “crash boxes”, which absorb the forces generated in a low-speed collision without damaging the rest of the body structure. Protective boxes can be easily replaced at a reasonable cost.

The straight sections of the side beams are made of high-strength steel, a ductile material, optimized for high energy absorption. This zone causes most of the deformation in a collision.

Additionally, Volvo chose to include cross beams on top because they provide significant protection if the car collides with, for example, a truck bed or a loading dock.

The part of the crossmember that curves towards the A-pillar is designed to act as a barrier that protects the cabin space and as a backrest against deformation. The design also helps reduce the chance of the front tire sliding in; Instead, the tire helps absorb the forces of the crash. This section is extremely rigid and made of very high strength steel.

A Historical Review

A rigid cross member connects the A-pillars and lower side beams. On each side they form an extremely rigid three-way fixation that helps preserve the cabin.

The new front structure is one of Volvo’s many patented safety designs and an important part of Volvo’s intelligent vehicle architecture.

Thanks to efficient design, the engines in the new Volvo S40 are 7.8 inches narrower than the 2.4 and 2.5-liter engines found in the S60 and V70. Since the engines are mounted transversely, the reduced width creates more space between the engine and the cabin. In a collision, the engine can be pushed up to 5.9 inches rearward before the crankshaft contacts the crossmember near the bulkhead.

The steering column can be deformed up to 5.5 inches. When deformed, the steering column moves horizontally to provide the best position for the airbag.
