went to pick up today after 4 weeks at the dealer. they could not replicate the grinding noise that occurs every so often on acceleration and the rattle was still there after a cold start. they stated they fixed the rattle by replacing the the vct solenoids but it appears that wasn't the issue. they did address the pivot arms for the sun roof, the tailgate closing by itself and the mirrors popping. They stated that they can't replace the turbo until it throws a "code". I asked what code will be thrown when its a mechanical noise of the flapper rattling in the turbo housing. I received no answer.
I'm a little concerned here. I'm worried I have a similar issue, I have a 2019 with almost 9K miles on it. Every so often, cold or not (that is, for example today, drove it for about an hour and still had this issue) I can hear a rattle from some place under the front of the truck, sounds almost like an exhaust rattle but only happens at low RPM. Had the windows down, and really only heard it when for example I was next to something like a high center divider. goes away once the RPMs increase and only happens during acceleration, never seems to happen under deceleration.
But here's my big issue, I'm considering buying the SPD downpipes (already have the turbo adapters but haven't installed them, doing them at the same time). I'm concerned dealers will give me the immediate middle finger if I try to claim a rattle down there after doing that type of work. Thoughts?
I hate rattles, had a rattle in my WK2 in a sunroof that took 3 years to figure out, turned out to be a missing nut during production, and took 3 engineers flying from detroit to my dealer after I emailed the CEO of Daimler... But damn it was nice when it was finally gone.
