Good evening, actually I was yesterday because of two other little things in the Volvo Forum. But as it is, one reads and reads. I stumbled over the puzzling cracks in the cylinder block. Our vehicles: S80 II D5 205 hp from 01/2011, 145,000km, freshly bought and XC90 D5 230 hp (Heiko), from 09/2012, now 65,000km, we have been driving for a year. It is quite clear to me that in the forum only those who have a problem report. the affected engines (percentual) as well as affected years of construction? It does not seem to depend on the mileage. Can one prevent anything to avoid the damage? The cars are fast but without ever racing with us, but have to pull 2-3 times a year a 2 tons caravan. Actually, with problem cases I have always had good experiences so far (Alfa 147 JTD 160.000km without problems, C220CDI with the vulnerable Sequentronic almost 300,000km without problems). But if I thank you, good evening.
