Just received a letter asking me to book in to have a free of charge Product Assurance Program Q159 carried out. It's specific to 2010MY 3.6 diesels and apparently takes 2 1/2 hours Anyone have any ideas what it's all about?

They'll have it for a couple of hours. The apprentice will be sent to the shops in it for the teas and burgers. They'll smear oily fingerprints everywhere and claim it's OK now.
