Its really not as bad as it sounds, as already said, most problems are caused by bad fuel, in all the years I have been working with Volvo engines I have not dealt with that many failures that have been serious, most problems I have diagnosed using the fault codes from the EVC display and not even plugged in the Vodia, that is only required when updating software, I could have done most of my work as a dealer without even having a Vodia, its realy so simple that once you understand how things work you will not regret owning one.
Onto to Yanmar again that's another story, when trying to sort issue with a 6 SY the only way forward was by using a Scania dealer with his laptop who could access what was necessary to identify the fault, that would probrably explain why the 6 SY never was a popular option here and never sold as it should.

I'd agree there AQP, when faults come up usually a chat with the owner then a sea trial you get a hunch where to go.
Yes I'd also agree that fuel is a major player but what I've also found most is faults down to poor installation especially electrical , poor positioning of engine components which are not bolted to the engine. However this now seems not too common since the passing of our Kidderminster based manufacturers.
