I recently had a turbo charger failure without any previous warning. It is a "new" 2007 Cummins engine in a new 2010 Damon Tuscany purchased as a new 2010. At first the diagnosis was the vgt actuator had failed and our Good Sam insurance was going to cover it. The next day however, Cummins sends a picture to the insurance people and I get a phone call from Cummins that MY bill is $7028.08 to replace the turbo charger. Cummins said there was rust. However, they also said that one of the freeze plugs had a pin hole in it and when they applied pressure to it, coolant leaked in. We are appealing the decision, that the primary failure was the defective freeze plug and the rust was a secondary issue.
What is this gauge that you mention that helps determine when its OK to stop the engine? Also did you get any assistance from CAT? Thanks.
