Volvo S80 - Recent Questions, Troubleshooting & Support - Page 2

Could it be that a previous electric defect killed the previous battery, and now the defect reflects as new problem?
Just saying in case resetting has nothing to do with making the problem go away.

Hi there's this website something like reliable-store and it is very amazing for manual for repairing servicing anything someone on fixya recommended it to me and I thank him even today They have full manuals and it's verrrrry cheap and mine I got free in offers 3rd time I bought it, I also had an issue with the file so the girl replaced it in 30 mins there is one website more but i don't remember its name it was 2 years back bitman something link this Try these out brother

just unhook the battery for about 20 minutes. if you have an anti-theft radio make sure you know the code and how to enter 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).

Why do you beleive there is a fault in the wiring?

Emobilizer needs to be programmed by the dealer.

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!

There may be problem with the mass air flow sensor (very common with Volvo). This causes the fuel system to malfunction.

You may have noticed increased fuel consumption, loss of power and general 'lazyness'.

Better to take it to authorized Volvo service for a checkup/fix.

Is there any problems with the car?
I'm assuming you mean the service engine soon light.
take it down to a local shop, and get them to put a scanner on it.
It'll show why the light is coming on, and from there you can decide what you need to do to fix the problem.

Hope this helps :)

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
