is it just a ploy to get owners to use only dealers for servicing ?

If you saw the lines of communication between the dozens of control modules you would be astounded , it's an incredibly complex network system . But that is the designers problem , we can't possibly understand it all together in the car .
99% of it runs as designed of course , but fine tuning is found to be needed to cure some minor undiscovered issues . Interaction unaccounted for in the design may be found later . The safety system is added to as time goes by as fresh accident data comes in , they may alter timings etc .
the emission EGR system has been tweaked a lot to get the cooler and valve working as designed .
Yes only dealers can sort the majority of problems out as they are the only ones with factory training , test equipment and back up , no one else can do anything as they are not trained on the specific systems . The only specialist here is the dealer .
The new xc 90 has been remarkably reliable mechanically , but the software has cured most of the small niggles and problems , that is one of the advantages of an electronic computer controlled car .
the same goes for anything these days .
