I took delivery of a ecodiesel in January 2015 and during second oil change (at 10000 miles) I removed the EGR tube located on inlet manifold to see the soot formation inside. Not pretty and I replaced the ECU with a unit from GDE and has until now at 92000 miles not had a single issue to report...
I removed the EGR tube at 15000 miles when I had the EGR eliminated in an attempt to improve the engine longevity and found the fouling inside rather worrying. Truck has currently 62000 miles and I will remove the tube again and compare the findings with others. Pictures attached is from 15000...
I have been recording the fuel consumption from new and did replace the ECU at 15000 miles with a unit from GDE. After the ECU upgrade the fuel consumption was improved slightly (approximately 2mpg) but more important cleaner oil was obtained and better engine power / respond. My best tank...
Yes, the oil will turn black on all engines gas or diesel, however sooner on a Diesel engine. EGR (exhaust gas recirculation) is a huge contributor to the rather early visual pulsation of the oil seen in our Ecodiesel (and other modern Diesel engines) despite the large oil sump of 10.5 liters. I...
