2005 Volvo S80 2.5 - Answered Questions & Fixed issues

Disconnect the cables then charge the battery

Sounds like a faulty microswitch. In the same way as you can't pull the car out park unless the foot brake is pushed (proved by a switch on the brake pedal) so the gear level will send a signal to say it is in the park position allowing you to remove the key.

Along with many of the others the bolts holding the brake caliper slides in place are stretch bolts. You torque them up as pe the first post and then its a twist of so many degrees. This stretches the bolt past its elastic limit. Once used just like an engine head bolt the bolt is scrap. I'm told its to keep the wieght down on the front. My personal feel is that its a dangeous practice because you know loads of Volvos will have had the bolts used for a second and third time.

It is an OBD2 communication protocol.

Contact Volvo directly to order it.

Check to see if there are any OBD codes. Might point you in the right direction. Most of the problems I've seen with Volvo trannies are because of shift solenoids, which can cause a host of problems. Dealers tend to always quote a new ($$$$$) transmission, but if the transmission does shift properly when it DOES shift, your "wear items" are probably OK, and the problem is in the "control items" like the shift solenoid, or possibly a sensor. At the very least, I'd try draining and refilling the transmission fluid (particularly if you haven't done that in a while), and would recommend adding 8-12 ounces of LubeGard Platinum (I'm normally skeptical of snake oil, but have seen that stuff "fix" a few transmissions that were acting really badly).

I have an S80, never had a problem. It's possible the key battery has "expired". Try your spare key. What about the car's battery if it is not good there may not be enough power to allow the Key to function properly. Are you sure it is the proper key? Antitheft and security features may require help from a Volvo dealer!

Get the service and repair manual with a diagram from the given link and fix the problem easily on your own http://toolsnyou.com/

changed the wrong sensors the code (p0057)refers to the heated oxygen sensor (HO2S) which is in the exhaust manifold before the cat converter code p 0172 refers to system too rich bank bank 1===causes ---intake blocked ---EVAP canister purge valve --- fuel pressure---EGR systems ---injector/s---HO2S If you replace the HO2S sensor/s then that will [robably fix all codes the heated oxygen sensor reads the exhayst gas and reports to the ECM to adjust the air /fuel ratio to get the engine to run within parameters when it is not working , it runs lean or rich

indicates what you suspect the noise could be sump pressure trying to pass the faulty PCV valve and pressure in the sump will blow oil out of weak seal and gaskets

I really think you should go to www.reliable-store.com they have got books on every vehicle and also how to service/repair it, parts info, wiring diagrams, electrical diagrams, fuse diagrams, error codes, etc everything

If you're comfy with manuals then i know few websites that can help you with it. Bcause I've bought it from various websites so I know how each site deals. try www.reliable-store.com Very helpful

if the rain drops are falling on your head , it is unlikely that it will be the sun roof more likely door drain holes blocked or plastic covering that covers all of the holes in the door has not been replaced allowing the water into the car behind the trim another point for water is blocked drain for the ac evaporator box so check that hose as well

Fuel pump?

hi there. see if this link helps you out. Volvo S80 Transmission speed sensor location Google Search

change the repair shop to an accredited service center that will use the scan tool first to save you money repairing by guessing is costly the codes will probably show an EVAP system problem or a fuel pressure problem
