Having problems with your 2005 Volvo S40 ?
How do you reset the check engine light on a volvo S40? I did my own oil change and it pops up every time I start my car.
The Check Engine light has nothing to do with changing the oil. The light is on because there is a problem with the emissions system. Even if you reset the light it will just come back on unless the problem causing it to come on is repaired. You will need to have the ECU scanned with an OBD2 scan tool. That tool will retrieve the code that has been set by the ECU. The code will tell you what part is being effected, but not necessarily what part or parts are defective. To determine that takes training, experience, and diagnostic skills. I suggest you seek professional help. If the engine is running fine there is no hurry but if it is not running as it should, then do not put this off.
The radio panel for 2005 volvo s40 2.4i is dark even with the radio on. You can see what is happening on the panel. Just 2 vertical lines show up.
