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).

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!

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

If you're finding it difficult to service/repair your car, get one of those online manuals. You'll not have to wait for others to answer,
or rely on mechanics and all. Plus I know a website that has very good manuals online, without expiry i.e. for lifetime.

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

its not reading earth the throttle position or the abs. or can even be the engine revs. low voltage can be a problem that causes this. a bad connection or even a faulty alternator. turn off then back on again is resetting the power and the longer on the weaker it goes to. like a bad regulator.

Sounds like the large power wire (starter wire) is routed too close to the VSS. Sounds silly, but it can keep the engine from running.

They are solenoids that go bad. If you replace one, replace all four solenoids. The kit costs about $100 on ebay. It is a difficult job gaining access to the inside of transmission. Pay someone that knows how it's done.

If the floor was wet, you need to replace the heater core. The s80 is the easiest core replacement I have ever done. It is under dash on the driver's side. Just remove the two bolts, slide the old core out and slide the new core in.

the 2002 s80 did have a problem with the cluster. I have one and I love the car. I went on ebay and found the correct cluster to fix the problem. If the displays are going off and on, replacement is the only fix. The 3 sets of numbers on your "new" cluster must be an EXACT match with the old clusters numbers. In other words, the cluster must be for a 2002 volvo. If the numbers match, it doesn't matter what model the donor cluster came from.
