The service light comes on every 5000 miles to remind you to change the oil & check fluids. It is reset with a special tool that connects to the OBDII connector.

turn the key switch to the run position and then turn the blinker on on the side thats freezeing and do a walk around the car checking the corosponding lights to the side that is on and froze. first check the bulb in the light thatis not on on the side that should be blinking. If thats not the problem then you have a bad ground on the system and you will probably have to add a ground wire to the side thats frozen but first check the bulbs!

I think I would check the thermostat.You can buy one that opens sooner..Like yours might open at 180...but you can buy them to open at 160....Flush your radiator..Might not be circulating good..cat converter could be slowing clogging causing pressure back tour you motor...Car will start back firing sometimes..loose acceleration... That's my list

You need to enter the security code!

Go to a local auto parts store for help. Obviously, the dealer does not wish to be bothered. And that car is less than 10 years old - parts should be available as per regulations in this country.

I would replace the flasher unit as well as Clean your Battery cables. Baking Soda and water work great for cleaning them, then coat all the connections with Di-Electric Grease.

We don't usually recommend a brand on fixya, so if it does not have synthetic oil now, any good quality 5w30 or 10w30 should do.

Not long and doing it yourself could save you a few hundred dollars from reports I have seen online.Please ensure your vehicle is securely supported if you intend doing the work your seld good luck

Here's a link showing you how to replace your PVC valve,takes about 20 minutes maybe. http://www.autozone.com/repairinfo/repairguide/repairGuideContent.jsp?fromSearchPage=true&pageId=0900c1528008c264&partName=PCV+Valve&partId=0900c1528008c264

That generally means the transmission, and most likely the PNP switch are malfunctioning. You can typically limp it along by pushing the button on the shifter and moving it from "1" to "P" back and forth a few times in rapid succession, but ultimately you need to replace the PNP switch. The OEM switch is about $170 and the aftermarket part is about $70. For this sort of thing, I'd use the more expensive factory part. They're available at FCPGroton, IPDUSA and eEuroparts and other places. Volvo PNP Switch 960 S90 V90 Genuine Volvo 9466013

If yours is the one with the cd player the code that came with the radio works for both. If you don't have the right code the radio and cd player wont work

That would mean your water pump is not working properly

I have found that if you disconnect the battery cables for about 5 mins then reattach them and that should reset the check engine light

I would check the ball joints and/or control arms

It's the bulb failure warning light. It comes on when the brake pedal is pressed if there is a defective brake light bulb. Check your brake lights - either a burnt out bulb or a bad connection caused by corrosion in the socket.

Yes it is a possibility to bend the valves, but I really think it is of timing. I would take the belt off but leave the pullys and gears, then align each camshaft to it's mark and do the same for the crank. Put the belt back on and tighten it then try turning it over with a socket on the crank and see how it feels before trying with the battery. You should have better results.John
