xc90 wont start, shows engine and oil light,

[Shala]

hi guys, just bought my xc90 privately 3 days ago. drove all ok. yesterday i spent the whole day cleaning the interior, the annoying interior lights come on everytime open a door and theres so many of them.. for a short period i had the stereo on. at 4pm i tried starting the car and it said low battery so i jump tarted the car with wifes car and drove for 20 mins. at 10.30pm i drove the car about 3 miles, had loud music as i was enjoying the good speakers it has, i parked for an hour. when i went back to the car it wouldnt start, a neighbour tried helping jump start but nothing happened, xc90 didnt even want to tick over.. i realised the engine and oil light came on. i had to leave the car there, 1 neighbour was nice enough to give me parking permit for the day.


what could be causing the problem and whats the best resolution to solve this issue?

kind regards
shala
