As you rightly pointed out in the begining, the modern deisels are way more advanced than their cousins of yesteryears.
Now a days deisels are easy to maintain, are relatively low on noise, are VERY fuel efficient, DO NOT spew out black smoke, have tremendous torque which is addictive, cost a tad over the petrol siblings but cost of running (read fuel bill) is MUCH lower. So basically have a lot going for them !!
The first & most basic fundamental thing is change of engine oil at reccomended intervals or preferable to change it even before the reccomended mileage. Keep air filters clean. Regular service is THE MANTRA !!!
Hope that helps !!
