Hey, so my friend got a XC70 P2, and he bought it with low oil pressure error, that only appears on idle, when you gently touch the gas pedal, it dissapears. Then another issue is that it randomly enters emergency mode, the car won't accelerate properly and it just feels kinda weird to drive. And yesterday when it entered the emergency mode, the car wouldn't go faster than 30km/h. The car was at the mechanic, he couldn't help, they just changed the oil and kept the car for a few weeks, charged 300€ for it, even though he changed his own oil like two weeks before taking it to the mechanic.
So what could it be? Should he just sell it as it is?
It's a 2.4T 147kw.
