Check Engine Oil Level Light Coming on when driving on interstate

My check engine oil level light comes on but only when after i've been driving on the interstate for about 20 minutes or more. I have a 2002 Mercedes Benz C320. What could be causing this to happen and why does the light not stay on? I just had an oil change.

Hi, this will happen when the oil sending unit(module) is malfunctioning. This a sensor that reads the information and sends the alerts which initiates the lights actions. Replacing this sending unit(module) will fix this issue. There is a more sever issue that may not be the case but, there is a chance. The oil pump itself may be malfunctioning. this could also trigger this alert as well. I suspect the sending unit may be malfunctioning.


please rate and have a great day...

How can I fix my car with the oil light coming on. The engine does intermittent jerking during driving


Oil light usually indicates LOW oil pressure.. Which will kill your engi ne and cause very expense repairs. FIRST Check oil level, If the level is good. You need to find out if the engine really has low oil pressure. A new oil pressure switch is about $8.00 you might start there. If the light still comes on its a good posibilty your car has bad oil pres.. To find out for sure you will need to install a Pressure guage and check the actual pressure.. If the Oil Level is good and you still have low oil pressure The engine has internal wear or damage.. You should not drive it till you fix the low pressure problem. rebuild or replace engine. The intermittant "jerking" can be unrelated to the oil pres problem or you engine is going away because of the pressure problem.

Check engine light is on. Engine sounds like it's knocking. And oil light is coming on. This 2008 Dodge Dakota has only 63,000 miles.


Sometimes that light means overfill oil
Sometimes after changing oil if they put too much that happens
Check the oil level on cold in level place (give it like an hour or so) for the light to reset
If after that the light still on take it to a tech.

Good luck

Engine rattling


Careful - had same problem with 2003 rav4 turned out it was nearly running with no oil even though the oil level warning light didn't light up - check your oil level before you drive the car again

2004 lincoln avaitor oil light comes on the engine shuts down


Does the oil light come on BEFORE the engine shuts down? I have to ask because it is NORMAL for the oil light to be on when the engine is not running. I had a customer that said the same thing just last week. After we wasted a bunch of time (which the customer ended-up paying for) checking the oil level, the oil pressure, and verifying correct oil pressure gauge, light, and sending unit operation, it turned out that the crankshaft position sensor was bad and causing the engine to shut down and it had absolutely NOTHING to do with the oil light - it was functioning as designed.

If the oil light is coming on before the engine shuts down, the first thing you need to do is check your oil level. If the oil level is OK, you need to check the oil pressure with a gauge to determine if there is an actual engine oil pressure problem or if the oil pressure sending unit, gauge or light is malfunctioning. Also, it is highly advisable to not drive the vehicle AT ALL if the oil pressure light is coming on while driving until the cause of the light coming on has been determined and repairs have been made. Otherwise, SEVERE ENGINE DAMAGE may result.

Just had my oil changed and the check engine oil level low light is coming on . But checked it and it's not low , just on the full mark . It comes on everytime I restart the car . how do I fix that ?After...


You have to reset the check engine oil level light. The light is just a 3 month reminder that lets you know when to change your oil. You have to hold the reset button on your dash for more then 5 to 10 sec. The procedure is in the owners manual that came with the car.

At red light engine seems like it wants to cut off.


try changing your pcv valve. if its dirty it may be causing the shuttering. as for the check engine light going on and off, you may have a bad gas cap. if the cap is faulty it will cause the engine light to come on at times because of a poor air to fuel ratio.

Engine Transmission Light coming on intermittently


low pressure in the tranny, did you check the oil level in park? if so you might have to check it in gear with someone holding it on the brakes, then re-check... hopefully it isn;t the pressure solenoid.... $$$$$$.... they can be expensive, cheers!
