Question about 2001 Volvo S40
Is my engine in trouble if the oil light stays on?
Posted by Anonymous on
Do Not Operate if the Oil Light is on!!!!!!!!! Get it to a Mechanic and have it checked to make sure that it is not a bad oil pump.

The best thing is to go to your local Volvo maintenance shop or Volvo experts to find out whats the problem..usually the coomon ones I think is the programs inside its ECU unit..you try this..ask the volvo experts to reset the ECU and lets see..if problem arise then it is no doubt you might need the sensor..hope this help..

This is a common issue particularly with vehicles that have had some neglect to the oil change routine. The VVT solenoid on the top of the valve cover gets clogged with thickened or sludged oil.
Replace the VVT solenoid and gasket with a new unit and clear the codes.

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.
