In the UK, the grills are on the UK nearside so they are forever drawing the rubbish out of the gutter and clogging up the vents, hence why Stagecoach stopped buying them (that and MANs at Euro4 were cr*p anyway) hence they are busy replacing MAN engines in Solos, Versa and Euro4 MANs with Cummins engines.
I have never heard the positioning of the grill and it sucking up rubbish from the roads as the reason for poor performance before.
I wonder if the same happens with the Merc Citaro in Europe?
With the radiator grill being on the near side, they should be ok in the UK - but in Europe, will presumably encounter the issues you mentioned with MAN vehicles in the UK?
With the engine now being a few euro ratings higher than the poor performer at Euro 4, hopefully performance/reliability has improved too.
