I am 145 miles from a Volvo dealership, I was wondering if anyone has any ideas on this. After I drive to get the engine warm I get a message the " engine system service required " and the triangle in the center of the dash is orange. The engine seems to run fine and when I hook my code reader up I get no codes, but when I erase codes it goes away till next time. About a month ago I got a code saying my oxygen sensor "fronts" was going out, I have new ones but have not installed them yet. Does that have anything to do with it??? Or does it have something to do with changing oil? If so how do you reset the oil change sensor???
Need Help ASAP
THANKS SO MUCH

 

Just a note, the code didn't say your O2 sensors were going out, they said they were out of range, big difference, which is why you need to make sure they really did fail and are not out of range because of another failure.

Some codes cannot be read with over the counter readers, you need to find a Volvo shop, whether it's a dealer or a place the specializes in Volvos to get the codes read, unfortunately there is not really a way around it.
