The check engine light is turned on by the computer when the computer detects a problem. what happens is the computer stores a code or codes with the sensor or circuit problem, the first thing you need to do is go to an auto parts store and have the computer scanned for stored codes. they will give you a printout with the codes. if you get me the codes i will be able to help you solve this problem, for example the code would read like this PO301 cylinder 1 misfire detected.get me the codes and list the year,make and ,odel with engine size and i will help. note; the auto parts stores scan computer free of charge. hope this helps good day.

Your dip stick tube is your fill tube for your transmission . Make sure your transmission oil is at opperating temp before servicing some instructions are written on the dip stick , Use a small funnel , Add a little at a time (cup). Use the proper fluid , check regularly

SOURCE: location of volvo s40 2003 oil filter

It is underneath near the oil pan. Not really a filter, but the cover to the filter. Should be a black round looking thing. Remove this, and the paper filter element is inside. Be careful not to crack or damage the cover.

SOURCE: Where is the fuel filter in a Volvo S40 2005

Yes that is correct. The only filter is inside the fuel tank, and as I recall its a non exchangeable filter. It just gets replaced with the fuel pump when it goes bad

Look down where the white circle is and you will see a black round casing with a 32mm (i think) nut on it. It helps to remove the air intake hose in front of the white circle for easier access.

I have a volvo s40 2.0t se the other day after i came back from a trip it was on tic over out side the house wen the temp gauge droped to cold and the revs went up to 1200 and a strong smell of fuel was...


First things first. Check your coolant level. If that is up to snuff, then have the engine data scanned, and see if your coolant temp sensor is out of whack. If it reads very low, the pcm will give the fuel management system directions to add alot of fuel. However , as I mentioned before, low coolant can cause the temp sensor to read a cold engine(it usually must be submerged in coolant) and cause the same problem. There are more things to check, but this is the place to start. If you have no luck with these suggestions, get back to me and we'll go furthur. Good luck!

Volvo 2006-i WAS driving it and for about week or two only for a second check oil light came on with really sharp turns and thats it. When i finally checked it the stick thing didnt register. Car is fine...


Yes, When you run an engine low on oil enough to cause the light to come on then damage is being done. It sounds like you caught it just in time. I would change the oil and filter for shure as soon as possible. Then I would Change them again In a week or two. Then you should be OK.

Random check engine light on 1999 1.6 xs s40 volvo


The light is indicating an emission system failure. Take the vehicle to your local Auto Zone or Advance Auto and ask them to scan your car for trouble codes, they will do it for you at no charge. Write the codes down and reply back to me and we can begin diagnosing the problem.
Good luck, let me know.

1998 VOLVO S70 INTERMITTENT CHECK ENGINE LIGHT, GOES OFF COMES ON NO EMISSION CODES


intermittent engine codes are not serious and it just indicates that one or more of the sensors is reporting a bad signal..at what ever time intervals.....this just means that as you drive , bad connections develops as a result of the movement for a second or long enough for the computer to detect a fault and then it goes back to normal....you can check for bad connections yourself by wiggling the wires with engine running and see if the light comes on ..which will tell you where the bad connection is and then fix it yourself or just wait until the connection gets really bad and the engine light stays on permanently .the computer will then store the code thats causing the fault and you'll know exactly where it's coming from.
