Dealer says my turbo actuator is bad. I'm right at 5 yr/100k, but they are telling me the actuator was only covered to 50k. It took 5 days for them to decide that the actuator is covered by the basic 50k warranty and not part of the "cummins diesel engine" or "powertrain" 100k sections. I have downloaded the warranty and see "turbocharger housing and internal parts" within the "cummins diesel engine", but can not locate further details. As this is a $3745 question, can anyone direct me to where I can find this in writing? Assuming that this is not covered under warranty, I've already been out of service for 5 days, and don't have time to send for rebuild. I have found a Holset actuator from M&D Distributors for $895, anyone have experience with this company?
