I hear that, about parts not necessary. Quite a discrepancy among those mechanics. All I could say is to find a mechanic who is familiar with Volvos. My suggestion,. without knowing what codes were given, is that possibly your throttle body needs cleaning. This is where the air enters the engine, and carbon or fuel deposits tends to build up there. It can get black and dirty over time, and cause problems like rough idle or hesitation. But anyway, find a smart and honest mechanic-not always easy, but they should be better than guessing after getting the codes.

You need a locksmith with the correct equipment. There is no "simple code" otherwise thieves would exploit it. Be sure and have the title available as the locksmith doesn't know if you stole the car either. Do call many places for prices as I just found out with getting a second key made for my 99 Ranger, prices ranged from $120 to $220!

You need to leave the key in the ignition in position I (accessory) for two hours, after that it will say code and you can input the code. The radio switches to "OFF" after three failed attempts with the wrong code. If you dont have the code call the dealership with your VIN and they can give it to you.

if the drive belt is still in position and its tension is correct then the obvious answer is that the steering pump has failed internally

If there is no external leak then it has to be burning the oil. This could mean worn rings or worn/misadventures valves.

Change the fan. Very easy.

Try make a OBD readout. Perhaps there are a troublecode stored in the system. The relay to operate the gasolie pump in the tank can be defective so the solder is getting hot and loses contact.

Might be the control switch, but that is unusual. Most likely it is the vacuum hose going to the damper controlling the defoger. If it was the vacuum line to the control, then it would blow defog all of the time.

Since you are a DIYer, I recommend a repair manual from your favorite auto parts store, or try filepeep.com if they have it, or manualslib.com. You will want it next time anyway.

The APP sensor is attached to the gas pedal. This sensor rarely fails. The most common problem with an APP ( accelerator position sensor ) is the actual throttle control motor on Volvo's. The throttle assembly may be contaminated with oil due to a plugged PVC system causing the oil to enter the breather hose and be sucked into the throttle assembly and electronics. It is rather difficult to inspect the throttle assembly as it is under the intake manifold, however, if the air intake hose is removed and there is oil in it, suspect this to be your problem
