I recently put a racing air filter on my s40 t5, i had to pull out the old air box and unmount the computer because it was attached. So after i remounted the computer i was getting this warning. Turns out i had not secured the computer properly and it was rattling around. Once i secured it this message went away and has not returned since.

 

Hey so I have a Volvo xc70 '05 with 310795 klm on it always maintained and I went recently on highway and got this message popping up day after. I normally only do city driving not highways.
so I m worried what it is. I m not sure how to get codes to appear or what this can mean. Please help.
