I don't know what processes they used to arrive at the failed turbo yet, I will be talking with their "experienced" technician later today to find out their diagnostics for the conclusion. When I drove it to the shop, there were strange noises coming from under the hood close to the location of the turbo, they sounded like a gurgle and low frequency whistle when I let of the throttle, which sounded to me that it may be the turbo.. It went into the limp mode when driven with harder throttle to accelerate, and the Service Electronic Throttle Light came on immediately, about a mile from the dealership. The P0234 code does indicate that the turbo may be malfunctioning, the variable vanes actuator may be a problem. However, I am just guessing.
Is it rude to ask to see the service technicians qualification, or this will piss them off to the point of making the repairs poorly? What would you suggest to do? This "experienced" technician has supposedly replaced several turbos on the ED, and I really don't know his customer skills to start asking qualification questions. A typical mechanic of my generation would get pretty pissed off by questions.
As typically, I have requested a visual inspection of all of the replaced parts for my own information and evaluation. And also I will request their inspection evaluation of condition of the related components that may be suspect. i.e. Air intake manifold, throttle body, MAP, TV, EGR valve, etc.
I really want to thank you for your info input on this. This is my first time with a serious issue on the ED.
