Had a small fleet up til last year and had an 09 Volvo with the same engine, it started acting the same way and after chasing the problem before finally determining it was the ECM I decided to go ahead and start with the ECM this time, but that hasn't solved the problem just yet, even with the 2 new engine harnesses. We'll check those spots for sure. To check the ecm ... New or not ... Testing the ecm for this known issue is as easy as banging on the ecm (almost hard enough to dent its casing bit not quite) while engine is idling. If it cuts out then its a bad ecm. Simple as that.
