Or more formally, "Voluntary Emissions Service Action 28F3/P1."

No specifics about what models or engines are covered, just "some
Volkswagen vehicles."

Someone asked earlier about reimbursement to people who had already
suffered coil failure and paid for replacement; there's a "Customer
Campaign Reimbursement Claim Form" included, although they don't make
any mention of it in the cover letter.
