Once I go in there and explain the issue, do I just tell them there is a TBS on the "static noise" and my PDIM needs updating?
Basically yes. Random static noise and that there is a TSB out. Then you show them the document that Pcolashan provided us with:
That is the official document number. Step 6 clearly states that if the version is CE or DA, then to replace the Module (does not give a part number).
Tell the dealer that there were two part numbers that GM provided and that 20985421 is the latest one. Then the dealership can order that part under warranty claim.
