OJ Avery Posted June 18, 2018 Share Posted June 18, 2018 Did I see on here that Mack says no longer replace ecm with an oil soaked harness? It has reached the ecm. Working on a 2009 mp7 w/ 07 emissions. Quote Link to comment https://www.bigmacktrucks.com/topic/53589-oil-in-harness/ Share on other sites More sharing options...
fjh Posted June 18, 2018 Share Posted June 18, 2018 (edited) JUST MY OPINION! If the truck is not under warranty it seems pointless to change the ECU unless your still having grief with it throwing codes just hose out the connector a couple of times and resemble it and see what happens! Its and extra 1000- 2000 bucks that you won't have to give TO THE VOLVO TRASH PEOPLE! We have done this dozens of times with good success rate!

OJ Avery Posted June 18, 2018 Author Share Posted June 18, 2018 So you still do the harness and the updated oil pressure switches I assume. Quote Link to comment https://www.bigmacktrucks.com/topic/53589-oil-in-harness/#findComment-400764 Share on other sites More sharing options...
