Hello, everyone!
I'm a proud owner of a 2003 volvo s60 D5, 5 speed, 400k km.
I had just serviced the car - oil change, and all the filters, oil, fuel etc. One day, while driving and passing another driver on the highway, I accelerated to around 120 - 130 km/h, when suddenly a notification appeared that engine needs service, and the car went into limp mode for the rest of the way, after turning the car off and on again, the message was gone and the car was running fine, aince then it has happened only once again. Do anyone have any ideas on what could've triggered that, since the car is just serviced?

Thank you!

You'd need to have the car scanned for the stored fault codes.
