Try changing the oil and filter with good quality oil and filter and see if
the air mixture gizzmo under the inlet manifold is working correctly or in
need of a cleanout ,as well I would check the oxygen sensor as it can make
smoke if its carpet .Then give it a good drive and rev out in the lower
gears .After this see if all is ok as often a good rev out is all the car
needs .Its a very young car to need any work yet ,go on give it a good rev
out Volvos need it every so often .My wifes 740 turbo did this puff of smoke
bit it was an oxy sensor now its done 237000klm and clean as clean .My sons
has done 300000klm no oil used .And mine has done 170000klm no leaks either
and no use of oil .We are not talking Japanese motors here work it out and
see the difference ..
