Hi there:Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Another term for excess fuel is "running rich." Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm. Excess fuel will usually effect engine performance, reduce fuel economy, and produce a fuel odor.How did the fuel get into the cylinder in the first place? Some of the causes of excess fuel are a carburetor that is out of adjustment, a faulty fuel pump, a leaky fuel injector, or a faulty engine computer or computer sensor. If black smoke is present, check the engine oil as in the white smoke example to make sure excess fuel has not contaminated it. Do not start the engine if a heavy, raw fuel smell can be detected in the engine oil. Call your mechanic and advise him of what you have found.Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.Thank you for using FixYa.

Remedy as necessary.

This usually means the computer is having issues!

This is really difficult... A friend of mine tried to fix this and it took over an hour. Anyway this is how he did it.. First take off the panel from behind the radio. (3x T25 screws) Then remove the big panel under the steering wheel.

Then you'll need to remove the accelerator/gas pedal. To do this remove the 3 x 10mm bolts underneath and the 2 on top. When there unbolted remove the gas pedal.
Drag the carpet back that's directly under the steering wheel to show the black cover panel with 4x 7mm screws that underneath. Take those screws out and the cabin air filter will be underneath. Replace filter and put everything back together EXACTLY how you dismembered it =)

the United states will do the samething. the volvo dealer here would need registration and proof of ownership first to cut or reprogram and key. they need the vin number. i would suggest maybe next time in florida, you can do this.

hope this fixes it. jeff

The power steering is actually ELECTRIC steering on this car Most common and basically only failure is 2 30 amp fuses in under hood fuse block Only other thing is mechanical and would set a trouble code and sat power steering on your dash. FYI. Jump Starting your car from the +- Terminals found near the FUSE box under the hood, will Blow the Fuses for the Power Steering. Always Jump start your car from the Battery Terminals in the Trunk

Locate the power steering pump and hoses on your vehicle. The power steering pump is located at the front of your engine, near the top of the motor. It will have a black fill cap on it that is labeled "power steering fluid."
1)Clean the outside of the pressurized power steering pump hoses and the power steering pump with clean shop rags to remove any oil deposits. Check the exterior of the lines to identify any signs of steering fluid leakage.
2)Start the motor and turn your steering wheel back and forth several times to cause the pressure in the steering pump to build up. Turn the engine off and recheck the hoses for fluid leaks. Examine the power steering pump for any signs of cracks or damage. If your power steering pump is damaged you need to replace it with a new pump by removing the bolts that hold the pump onto the bracket, taking the pump belt off the pulley and disconnecting the hoses. Replace the power steering pump by reattaching the hoses with a screw clamp and attaching the pump to the bracket. Place the belt around the pump pulley and apply pressure by pulling back on the pump and tightening the belt by using a socket wrench to tighten the bolt on the bracket. You can find a power steering pump for your vehicle at your local automotive.
3)Check the fittings and clamps for any signs of wear or leakage and tighten any loose clamps with a screwdriver. Inspect the hose leading from the power steering pump back into the firewall that leads to the steering wheel. If you find that a leak has developed in the power steering hose that leads to the steering column, consult a mechanic or take your vehicle to a local service center and have an inspection done.
4)Remove damaged power steering hoses by taking the cap off of the power steering pump and then unscrewing the clamp on the hose. Recover draining power steering fluid by placing a clean container below the hose or power steering pump when you loosen the hoses and allow the fluid to drain into the container.
5)Repair power steering hoses where the damaged area is close to the end of the hose by trimming off the affected area with a utility or sharp knife and reattaching the hose with a screw clamp by tightening the clamp with a screwdriver. For damage that is in the middle of the hose or near a section that can't be repaired, replace the hose with a power steering hose that can be purchased from any automotive supply store in your area or online at an automotive supply website, such as the ones listed below in the resources section, and connect the new hose to the power steering pump with a screw clamp.
6)Fill the power steering pump to the proper level with power steering fluid and replace the cap. Start the vehicle motor to test the system. Once you have verified that the power steering system is working properly, shut off the engine.
