Freightliner Dogget diagnostic report

My 2012 cascadia was having heavy blow by so turned it in to a freightliner Dogget service center. They did diagnostic test and basically need a overhual. I do have a warranty and submitted the claim. The issue is the diagnostic paperwork does not have detail report. No codes or breakdown if issues. Only thing it states is basically what I told service . Heavy blowby and used plenty of oil. The warranty center needs the detail report but Dogget is telling me they dont have it or only way to get detail diagnostic is by breaking down engine. I paid $400 for diagnostic run. This is my 1st bringing in my truck for a service. Should they have provided me with the detail diagnostic report when I paid? I just have a gut feeling they didn't do one and charged me... went by the blow by and figured overhaul.

 

The report that was given to me only states engine has excessive blowby and used 2 gallons of oil... I am comparing my report with my brothers when he serviced with Dogget. His has more detail with codes and actually says under sold operations banner Express assessment Diagnostic while mine just has General.

 

Ah thanks. Will give them a call

 

Yes. Basically. I called the service center. Spoke with the service manager who actually is the person who initially looked at my truck and told me possible over hual just by looking at it. Anyways I called and asked about my diagnostic report and he went on defense. That he rather speak with my warranty. Told him that he can but they still want to see report to justify the warranty. I asked him directly if what he did was a visual test instead of computer. His answer was vague. Didnt give direct answer.Said he been in business for 40yrs that he can tell. So basically $400 for a service that was not performed I'm guessing. And this is a freightliner service center.

 

and yes I should've been on point about the report initially. I didnt know how it should be. Lessons learned. But still going to fight this.

 

Ah. No Dyno report. Just found out it visual test.
