Indeed sounds like intercooler failure popped your turbo. But I think the more pertinent question is why did the intercooler fail so early?
turbo popped is jargon for failure, codes are codes the trucks flash fault codes that the scan tool pics up and indicates XYZ issue. I don't see whats wrong with heat sensor, intercooler lines or DPF full of oil. These are the terms, we could witgenstein it and start calling them thing-a-majigers connected to the watsitcalleds?A conclusion that I am rapidly coming to is that a lot of these reports are not technically correct. A lot of the problems that we hear about on the forum have been misinterpreted and/or confused. The information is second or third hand by the time we hear it. As an example, non-technical terms such as:
turbo popped
intercooler lines
DPF full of oil
heat sensor
codes (what codes)
And that isn't the fault of the poster, as he us just trying to convey information that one or more techs passed on to the service manager and then to the owner and finally to us.
