What do you need to know? What symptoms do you have?

Check for fault codes. If you have a RR wheel speed sensor code 99% of the time it is a bad control module. If it is anything else have test and replace the component. Control modules are a VERY common issue.

You can reset it with the buttons on the instrument cluster. You need a small pin to depress them. They are real small.

There are numerous freeze plugs located on the engine block. You need to be more specific.

Replace the vehicle speed sensor first.

Turbocharger waste gate solenoid circuit issue.

Check fuses first. Fuses ok access the fan switch and check for power to and thru the switch.

If the odometer stopped but it shows speed it is not the cable. There is a small plastic gear in the speedometer which will strip if you reset the trip odometer while the car is moving. Any speedo shop can repair it

Not a code. Does not exist on any of the charts I have looked at.

Need to remove the instrument cluster, disassemble and replace the stripped gear in the speedometer drive motor.

Then you have the incorrect transmission for the car.

Not a lot of websites offer free manuals. I tried searching for the volvo model 850 turbo on a torrent search and found it. Torrents are a p2p file sharing. They can be risky to download just because of jerks who puts viruses in there. I also can find virtually any repair manual on any model car at my local library and its free. Hopes this helps.

If you have good compression then I would bet that your PCV System is clogged. http://www.ipdusa.com/ has the parts at a reasonable price as a full kit. You will have to pull the Intake Plenum/Manifold and you need to be careful as the plastic lines are fragile but with caution and patience it can be done at home.

Check the main Brake light switch that is activated by the brake pedal arm.

You are burning oil, it could be coming from a blocked PCV System. If it is plugged it is best to replace the entire system and you have to remove the intake manifold to get to it.

Replace the belt and retractor.

Go to IPD's Web Site, good prices, great service and lots of High Performance Goodies. http://www.ipdusa.com/
